Draw Music: Line to Song · WestPoint Store

# Five weeks late and still 「drawing lines into songs」: a cheap Android copycat gets only 20k installs

**What it is** An Android music doodle tool where you draw lines with your finger and they turn into melodies. It has ads and in-app purchases, and was made by WestPoint Store, a Vietnamese tool-app factory.

**Why it took off** It didn't take off on its own. The original, play_music_theory, went viral on TikTok. Its Android version came late and costs money, so users searching Google Play for 「draw music」 found it through the matching title and (presumably) paid acquisition, picking up a small slice of the traffic.

**C** **How to follow it** Don't copy this one, the theme is already taken; copy the playbook: watch for the next creative toy that blows up on TikTok while Android has nobody on it, ship a free version within two or three weeks, use the original keywords in the title, and run TikTok UGC ads.

Grade C: This is a third-wave follower. The theme already has 6+ clones on Android and 1.65M at the top. The window has closed. What's worth learning is how fast hot-trend clones arrive, not following this app itself. Few people outside the niche know about it

In Sep 17, Tala Schlossberg, a Brooklyn animation artist, posted a TikTok with the caption 「see what your dream vacation sounds like」. She drew waves, a sun, and palm trees on a grid, pressed play, and the shapes turned into a looping little melody. The video has 12.5M views and 1.01M likes to date. Her web app is called visual instrument, and it's play_music_theory. Six weeks later, on Oct 27, WestPoint Store, a Vietnamese tool-app factory, listed Draw Music: Line to Song on Google Play. In ten days it got about 20k installs, and its chart rank was already sliding. This piece is about how money was split across the Android clone wave: whoever got in first got the traffic.

### What it is

A tool that turns line drawings into melodies. Your finger draws a stroke on the screen; the higher the line, the higher the pitch, and the further right, the later it plays. The store listing's first line reads 「One line. That's all it takes to start a song.」 Behind the canvas is a 32×20 grid (32 beats, 20 pitches). Strokes snap to the grid, so a shaky hand still lands on the beat. Scales can be locked to pentatonic, major, or minor, and the copy says 「no wrong notes」. Tempo runs 40 to 240 BPM, with sounds like electric piano, marimba, synth, and bells, plus a template library of birds, animals, and landscapes you can tap to hear.

These features are largely copied from the play_music_theory web version: the grid, scales, WAV / MIDI export. The original has them all, and so do the other Android clones in the same wave.

It has ads and in-app purchases, with individual items from $4.99 to $9.99 (per the Google Play store listing, 11-06).

### How it rose and how it fell

Cumulative installs as shown publicly on Google Play:

| Date | Total installs | Notes |
|---|---|---|
| 10-28 | 1,001 | Day two after launch |
| 10-31 | 7,390 | About 2 thousand per day |
| 11-02 | 15,067 | Peak, about 3.8k a day (estimated by third-party AppstoreSpy) |
| 11-05 | 17,697 | Down to about 900 a day |
| 11-06 | 19,711 | +2k that day |

It only charted in the Music category's Top Free list, never in the overall chart or Top Grossing. Its best rank was Korea #37 in Nov 1. It reached #62 in the UK, and sat in the hundreds in Vietnam, Brazil, France, and Mexico. By Nov 6 it was down to Korea #125 and Vietnam #180.

Rating 3.3, about seventy reviews, almost all 1 and 5 stars, with none at 2 or 4 stars. In Nov 3, 1-star reviews still outnumbered 5-star ones, but two days later 5-star reviews passed them by 17. Ad-heavy tool apps often show this kind of distribution. Whether they guided users toward good reviews can't be seen from outside (unverified). The reviews are blunt:

> 「Everything costs money and you can't even save. Not recommended.」 (Mark McFarlin, 11-02, store listing)

> 「A dump full of ads.」 (a Russian-speaking user, 10-29, store listing)

### Who sparked the demand

Not it.

Drawing to make sound is an old idea. Google's Chrome Music Lab had a free Song Maker and Kandinsky back in 2016 and 2017. Between 2023 and 2025, Vietnamese developers also shipped a few similar iOS apps, each with only a hundred or two ratings. September was revived by Tala's aesthetic and TikTok: in Sep 16, one video got 3.65M views, and the 17 video reached 12.5M. She says on Instagram that she had 1.5M unique visitors in her first month and hit #1 on the paid charts (unverified).

The original's Android version didn't launch until Oct 11, and it's paid, with only 1,602 installs. People on TikTok who search Google Play for 「draw music」 find a row of free clones.

### Who's competing for it: it's in the third wave

Google Play data, 11-06:

| App | Developer | Launched | Total installs | past 7 days |
|---|---|---|---|---|
| Draw Music: Sketch to Sound | Banix Studio | 10-02 | 1.65M | +680k |
| Draw Music Maker: Doodle Pad | BigSoft inc. | 10-15 | 227k | +160k |
| **Draw Music: Line to Song** | **WestPoint Store** | **10-27** | **20k** | **+19k** |
| Melodee: Sketch And Draw Music | WEGO Global | 10-27 | 11k | — |
| Draw Music: Sketch Your Melody | Tokii Apps | 10-21 | 2,481 | — |
| Draw Music: Doodle to Melody | Bright Box Apps | 10-24 | 1,091 | — |
| play_music_theory (original Android version, paid) | Tala Schlossberg | 10-11 | 1,602 | +708 |

Android demand exploded between October 19 and 21. Banix had 19k cumulative by Oct 127, added about 21k in one day on 370 (AppstoreSpy estimate), and had reached 25k by 910. It ranked #1 on Poland's free Music chart, reached #128 on the US overall chart, and placed in the Music Top Grossing charts of a dozen countries.

Putting launch dates and install numbers side by side, the pattern is clear:

- 2 weeks behind the original (Banix): 1.65M

- 4 weeks behind (BigSoft): 230k

- 5.5 weeks behind (WestPoint): 20k

Banix and BigSoft both bought TikTok creators and UGC videos (some tagged #ad, some from dedicated UGC accounts). WestPoint, searching TikTok under its own name, finds not a single video.

One more detail: Banix, BigSoft, and WestPoint all use the same developer-site template, and the ad-config domain WEGO uses shares a package-name prefix with WestPoint's. These may be different fronts for one Vietnamese distribution network, all pushing the same theme (inference, unverified).

### Where users come from

- **Store search, riding the same keyword.** The title is 「Draw Music: …」, identical to Banix and BigSoft. TikTok videos just say 「draw music」, and users search for it and happen to find this app. The countries where it charted (Korea, UK, Vietnam, Brazil) are exactly Banix's strongest markets (inference, fairly confident).

- **Paid acquisition.** Listed two days ago with only 1K installs, yet it's already on the Music Top Free chart in 4 countries. Vietnamese tool-app factories usually use Google App Promotion plus ads to break even (inference, no ad records found).

- **Cross-promotion.** The same developer's Learn Guitar has 1.78M installs, and has added 90K in the past week. It's also in Music, so cross-promoting is easy (inference).

- **TikTok creators: none.**

WestPoint has a dozen-plus apps: phone clap finder, PDF reader, charging animation, AR tracing, World Cup scores… whatever theme is hot, they build. For them this one is just another lottery ticket.

### Where the money comes from

Interstitial ads plus in-app purchases. Never charted in any top chart, so revenue is likely tiny (inference). Reviews say users hate having to pay to save and the ads being too heavy. Reviews of BigSoft, a similar app, are almost all complaints about several ads popping up on launch and ads covering the play button.

### If it were you

**The short take** : skip this one. The theme is already split up on Android. The useful part is the table of how many installs you get by launching a few weeks late. When a viral creative toy hits on web or iOS and the original never shipped on Android or charges for it, a free, ad-supported Android version can catch the search traffic TikTok sends, but the window is only two or three weeks.

**Who it's for** : small teams with an ad-monetized tool-app framework, who can ship a new package within a week and know how to run Google App Promotion. You're not building another Draw Music. You're watching for the next viral creative toy that TikTok pushes while Android has nobody on it.

**Who it's not for** : indie devs hoping to slowly build word of mouth around a single app. The features can be copied in a week, the original owns the aesthetic and community, and the top clones own the volume. You can't get traction from either side.

**How to do it** : each day, scan TikTok for "web / iOS mini tool" videos with millions of views. Check whether Google Play has a free version, or only a paid original. Then ship a version with the core mechanic within a week. Use the exact term people say in the video as the title. To beat the clones, reverse the two things reviews complain about: make saving and exporting free, and keep ads off the play button.

**How to get users** : grab the exact keyword in store search. Also find UGC accounts on TikTok and buy placements for videos like "I drew an X, listen to what it sounds like." Banix and BigSoft both did this. WestPoint didn't, and that's the gap.

**When to be early by** : for the draw-a-line-to-song theme, the window has already closed. For the next similar hot trend, you need to ship within two to three weeks after the original video goes viral.

**Signs you're reading it wrong** : (1) if December's daily installs stay in the thousands and its rank recovers, the theme still has a Android long tail, and late entrants can still catch some of it; (2) if Banix's daily installs have also dropped to the thousands, the demand was simply short-lived, even the number one app can't hold volume for long, and this kind of "chase the trend clone" play earns less than it looks.

**Research notes: competitor table, acquisition evidence, full research report**

Competitors

| Name | Where | Launched | Scale | How it differs from this one |
|---|---|---|---|---|
| play_music_theory(Tala Schlossberg) | Web | Mid-2026-09 | TikTok single video 12.5M views, account 49.6K followers; creator claims 1.5M unique visitors in the first month and #1 on the App Store Top Grossing chart (unverified); official Android version 10-11 listed, paid, 1,602 installs | The original is a paid visual instrument by an artist, with taste and community. WestPoint is a free, ad-supported feature clone with no originality. |
| Draw Music: Sketch to Sound(Banix Studio) | Android | 2026-10-02 | 1.65M installs, +7K in the past 680 days; #1 on Music Top Free in Poland, overall #53 in Poland and #128 in the US; charted on Music Top Grossing | Same mechanic and naming. Banix entered 25 days earlier and bought TikTok UGC, and its volume is 80× WestPoint's. |
| Draw Music Maker: Doodle Pad(BigSoft inc.) | Android | 2026-10-15 | 227K installs, +7K in the past 160 days; #4 on Music Top Free in the UK, #8 in the US | 12 days early, with TikTok UGC placements. Reviews are almost all complaints about too many ads. Features are nearly identical to WestPoint's. |
| Melodee: Sketch And Draw Music(WEGO Global) | Android | 2026-10-27 | About 11K installs | Launched the same day, similar scale. Its app-ads.txt is hosted on bzkapppub, sharing the bzk package prefix with WestPoint. Possibly the same network. |
| Draw Music: Sketch Your Melody(Tokii Apps)/ Doodle to Melody(Bright Box) | Android | 2026-10-21 / 10-24 | 2,481 / 1,091 installs | Smaller followers. WestPoint is a bit better than these. |
| Chrome Music Lab Song Maker / Kandinsky | Big-company features | About 2016~2017 | A free web tool from Google, often used in education | Same grid-based melody drawing. Free, no ads, but it's not an app, and it didn't ride this wave of TikTok attention. |
| Sound AI: Draw Song AI Maker / Melodic: Music Draw & Painter | iOS | 2023-11 / 2025-04 | US store 223 / 177 ratings | An earlier, similar iOS mini app that never took off. The mechanic isn't new; September's spike was reignited by Tala's content. |

Where users come from

- Inference **Store search + name riding** : the title is "Draw Music: …", same as Banix and BigSoft. The countries it charted in (South Korea, UK, Vietnam, Brazil) overlap with Banix's strongest markets. The TikTok UGC only says "draw music," so users searching Play for that term will see an app with the same name.

- Inference **Paid acquisition (AdMob / Google App Campaign type)** : on day 2 after launch, with only about 1,000 installs, it was already on Music Top Free in 4 countries. This is the usual Vietnamese tool-app factory playbook. No ad library records found.

- Inference **TikTok creators / UGC** : TikHub searches for "draw music line to song" and "westpoint draw music" returned none of its videos. Banix (#ad) and BigSoft (UGC accounts like tooinfluenced_) were buying placements in the same period. WestPoint didn't follow.

- Inference **Cross-promotion from the same developer's apps** : the same developer's Learn Guitar has 1.78M installs, +7K in the past 91 days, and is also music-focused, so it can drive traffic. No direct evidence.

- **Verified** **Off-platform hit (play_music_theory went viral)** : @play_music_theory's 09-17 video has 12.5M views, and its 09-16 video has 3.65M views. Android demand took off between 10-19 and 21 (Banix alone added 370K in one day).

## Draw Music: Line to Song (WestPoint Store): why it got traction

> Channel: Google Play | Package com.westpoint.drawmusic.drawsound | Store launch 2026-10-27 | Research date 2026-11-06

### Bottom line

It has no story of its own. It's the **third Android clone** to enter the draw-a-line-to-melody wave. The source of the wave is American artist Tala Schlossberg's play_music_theory, which went viral on web and TikTok in September. The real Android winner was Banix Studio's Draw Music: Sketch to Sound (launched 10-02, 1.65M installs). WestPoint is a Vietnamese tool-app factory that followed in late October, riding the "Draw Music" search term and the leftover demand, and picked up about 20K installs. Its category rank is already slipping. Saying it "took off" overstates things. It rode the trend and got a small slice of volume, not traction it built itself.

### 1. Data (our googleplay library, 2026-11-06)

| Date | Total installs | Notes |
|---|---|---|
| 10-27 | 615 | AppstoreSpy estimate; 10-25~27 already at about 205/day, suggesting the store launch date may have been reset, or AppstoreSpy averaged the backfill. |
| 10-28 | 1,001 |  |
| 10-31 | 7,390 | 10-29~31 about 2,130/day |
| 11-02 | 15,067 | 11-01~02 about 3,838/day (peak) |
| 11-05 | 17,697 | 11-03~05 dropped to about 877/day |
| 11-06 | 19,711 | +2,014 that day |

- Charts (chart_rank; only ever on the Music category Free chart, never overall or Top Grossing): best in South Korea #37 (11-01), UK #62 (10-30), Vietnam #95, Brazil #149, France #175, Mexico #175. 11-06 only South Korea #125 and Vietnam #180 remain; the UK, Brazil and Mexico have dropped off.

- Rating: 3.3 stars, 72~74 reviews. The histogram is 30 1-star and 41 5-star, with 2~4 stars at zero (app_snap 11-05). This kind of two-ended split is common in utility apps with heavy ads plus an in-app prompt asking for ratings. At 11-03 it was still 36 1-star vs 24 5-star; over the next two days the 1-star count dropped by 6 and the 5-star count rose by 17. Could be a rating cleanup or a review-prompt push, unverified.

- Monetization: contains ads; IAP items $4.99~$9.99 (store page). No Top Grossing ranking.

- Developer: WestPoint Store (email phuongculinh2015@gmail.com; package prefixes include com.westpoint, com.appbzk, com.gearvn, com.bzkapp; from the email and package names, a Vietnamese team). The store has a dozen-plus apps: phone clap finder, PDF reader, charging animation, expression merge, AR tracing, World Cup scores… Its top app is Learn Guitar: Chords & Tabs, 1.78M installs, +7K in the past 91 days. A classic tool-app factory that builds whatever theme is hot.

### 2. Competitors: this is a clone wave, and it ranks third

**Source (non-Android):**

- **play_music_theory** (Tala Rae Schlossberg, an experimental animation artist from Brooklyn): a web "visual instrument" where you draw shapes on a grid that loop into music. You can export WAV/MIDI, and the upgrade costs $4.99. The TikTok account @play_music_theory has 49.6K followers and 2.22M likes; its 2026-09-17 video has 12.5M views and 1.01M likes, and its 09-16 video has 3.65M views. On Instagram she claims "#1 in all paid apps, 1.5M unique visitors in the first month" (instagram.com/talaschlossberg, from a Jina search summary, not opened to verify). It later reached the App Store. The official Android version, net.playmusictheory.app, launched 10-11, is paid, and has only 1,602 installs (googleplay library).

**Android clones (googleplay library, 2026-11-06):**

| App | Developer | Launched | Installs | past 7 days | Best rank |
|---|---|---|---|---|---|
| Draw Music: Sketch to Sound | Banix Studio | 10-02 | 1,650,638 | +679,621 | Music Top Free: #1 in Poland, #2 in the UK / Japan / Vietnam; overall #53 in Poland, #128 in the US; Music Top Grossing #177~184 across a dozen-plus countries |
| Draw Music Maker: Doodle Pad | BigSoft inc. | 10-15 | 227,316 | +163,316 | Music Top Free: #4 UK, #5 Canada, #8 US |
| **Draw Music: Line to Song** | **WestPoint Store** | **10-27** | **19,711** | **+18,710** | **Music Top Free South Korea #37** |
| Melodee: Sketch And Draw Music | WEGO Global | 10-27 | 10,867 | — | — |
| Draw Music: Sketch Your Melody | Tokii Apps | 10-21 | 2,481 | — | Music Top Free US |
| Draw Music: Doodle to Melody | Bright Box Apps | 10-24 | 1,091 | — | — |
| play_music_theory (official Android version) | Tala Schlossberg | 10-11 | 1,602 | +708 | Music Top Paid US |

Banix's curve: 10-19 cumulative 127K, 10-21 one day +370K (AppstoreSpy estimate), reaching 10-25 910K. The Android demand spike peaked between 10-19 and 21. WestPoint launched 10-27, catching the tail end of the wave.

**Earlier similar products:** Chrome Music Lab's Song Maker / Kandinsky (free Google web tools for drawing sound, around for years), FL Studio's draw-a-melody tutorials, and Vietnamese developers' iOS apps from 2023~2025 years ago: Sound AI: Draw Song AI Maker (223 rating) and Melodic: Music Draw & Painter (177 rating). The mechanic isn't new. September's spike was reignited by Tala's aesthetic and TikTok.

**Possibly the same network:** Banix, BigSoft and WestPoint all use the same developer website template, `app-ads-<name>.web.app`. WEGO Global's app-ads.txt is hosted at `bzkapppub.web.app`, and shares its package prefix (com.appbzk / com.bzkapp) with WestPoint. These may be different fronts for one Vietnamese distribution network (or shared outsourcing / templates) all piling into the same theme. Unverified.

### 3. Growth tactics

1. **Store search + name riding (main, fairly confident)** : the title is literally "Draw Music: …", the exact naming scheme of Banix and BigSoft. Much of the TikTok UGC only says "draw music," and users searching Play for that term will run into it. The countries where it charted are also Banix's strongest (South Korea, UK, Vietnam, Brazil).

2. **Paid acquisition (inferred, no direct evidence found)** : Day 2 after launch, with only 1,000 installs, it charted on the Music Top Free charts in 4 countries at once. The usual playbook for Vietnamese team utility apps is AdMob / Google App Campaigns plus ad monetization to recoup. Didn't check the ad libraries, and saw no TikTok ads from it.

3. **TikTok creators / UGC (none found for this app)** : Searched TikHub for "draw music line to song" and "westpoint draw music". Not one result was theirs. Over the same period Banix (#ad, decker1k) and BigSoft (tooinfluenced_ 26k views, plus UGC accounts like degreatugc and joshstacks) were running creator UGC. WestPoint didn't follow.

4. **Cross-promotion from the same developer (inferred)** : The same developer's Learn Guitar has 1.78M installs and is also music-focused. It could push traffic to the new app via interstitials or mutual promotion. Not verified.

### 4. Its differentiation

- The store listing sells a 32×20 grid snap, scale locking (pentatonic / major / minor, so no wrong notes), 40–240 BPM, color-coded multi-instrument layering, a template library (animals, landscapes), offline use, and WAV / MIDI export. Most of this is copied from the play_music_theory web version (grid, scales, WAV / MIDI export were all in the original), and Banix and BigSoft have it too.

- The only real difference is copy that stresses "one stroke, a song" and "no wrong notes," with Line to Song in the title. **That is not differentiation, and it's not why it got installs.** It got installs from topic heat plus same-name search.

- On experience: BigSoft's reviews are almost all complaints about too many ads (up to 5–8 ads on launch, ads covering the play button). About 1-star reviews make up 4% of WestPoint's ratings, probably the same problem. The database has no review text for it, so unverified.

### 5. How many people know about it

- This app: no media, X, or TikTok coverage, revenue not public, **few people know about it yet** .

- This topic: **already widely discussed and crowded** . The original has tens of millions of TikTok views, and accounts like LevelEighty on Facebook have covered it. Android already has at least 6 clones, and the leader Banix is at 1.65M.

### 6. What to borrow

- The play is "trend tracking + fast cloning": a viral creative toy appears on web or iOS, the original hasn't shipped an Android version or is slow to (the original's Android version is paid and launched late), so a free, ad-supported Android version catches the search demand from TikTok. The window is short. Banix entered 2 weeks late and got 1.65M, BigSoft entered 4 weeks late and got 230k, WestPoint entered 5 weeks late and got only 20k. **Whoever enters first gets the installs.**

- The title uses the exact words users search (Draw Music), which does capture search traffic.

### 7. Uncertain

- Whether it used paid acquisition, in which countries, and how much it spent: no evidence.

- 10-25–27 already has installs, and the store's launch date 10-27 may have been reset.

- Whether the split between 1-star and 5-star ratings reflects incentivized reviews or rating manipulation.

- Whether Banix, BigSoft, WestPoint, and WEGO belong to the same distribution network.

- Revenue: it has IAP but hasn't charted on Top Grossing, so revenue is likely small.
