# Lock the car in the center of the frame: why an iOS video-editing tool, three and a half years old, didn't take off when moved to Android

**What it is** A phone video-editing app. Tap a car or bike in the frame and it locks the subject in the center while the background moves behind it, plus stabilization, speed ramps and effects, built for people who shoot cars and bikes for TikTok.

**Why it got traction** It never really took off on Android: the iOS version has been around for 2023 years and built a small base of word of mouth through before-and-after tutorials with a few hundred thousand to over two million views each. The Android version came 2026-09 later, and its growth has been flat.

**C** **How you could follow it** Don't go head-to-head on car-scene tracking. Pick a community nobody is speaking to directly yet (plane spotters, equestrian, kids' ball games, etc.) and build the same one-tap effect for them. Use the Tracket playbook: post one before-and-after a day using other people's original footage, and @ the original creator.

Grade C: The car scene already has Motion Track and Tracket, both spanning two platforms, with CapCut free as a fallback. The main developer didn't break out on Android either. What's worth learning is turning a pro effect into a one-tap tool for a specific community and a zero-cost TikTok demo approach. Copying the product itself isn't worth it. Few people know about it yet

On the same day in Nov 2, two mobile motion-tracking apps each posted a video on TikTok. Tracket Motion, from a Ukrainian indie developer, used an old-school title, "Testing my motion tracking video editor app using video from @aleksandrbaranovskis", and got 187k views. Motion Track, from a small studio in California called Morning Avocado, posted an Aston Martin Vanquish and got 742 views. Motion Track went live on Google Play in Sep 22, and got roughly 2,500 installs in six weeks. This piece covers what it actually does, how it held on iOS, why it didn't take off on Android, and what's left in this lane for the next builder.

### What it does: the subject stays still while the world moves

There's a group of car people called spotters who film supercars on the roadside, at car shows and at meets. Handheld footage shakes, while the car is still moving. What they want is an edit effect: the car pinned dead center, the background flowing past it. Doing this used to mean tracking and stabilizing in After Effects. CapCut has tracking, but people often complain it isn't stable.

Motion Track turns this into three steps: tap the car, let it track, and fill the edges with blur. The first line of the Play Store description speaks directly to this crowd: "Lock a car, scooter or mountain bike steady in frame, parked at a meet or flat out on the road." All processing happens on the phone. Videos aren't uploaded, and no sign-up is required.

后来它一路加功能:普通防抖(三档强度、三脚架模式)、变速和慢放、字幕、调色、遮罩、人脸打码、41 种特效、4K 导出。iOS 上三个月发了 25 个版本(6.19 在 7 月 30 日,6.44 在 11 月 5 日,App Store 版本记录),正在从一个「追踪工具」长成一个「围绕运动的剪辑器」。

### How it held on iOS

The iOS version launched in Apr 2023 9 under the name "Motion Track: Follow a Subject". It was later renamed "Video Stabilizer" to target the big search term "video stabilization." The UK and Australian stores use "Stabilise", and the German store uses "Stabilisieren" (likely ASO work). As of Nov 6, the US store had 411 ratings at 4.7 stars (App Store), Australia had 220, Sweden 83, and the Netherlands 74. Three and a half years brings in these numbers, which is not a lot, but the users are concentrated.

What really pushed it into the mainstream was two TikTok tutorials. In Apr 2026 6, the official account @motiontrackapp posted a before-and-after clip, sourced from the car edit account @mbncars, titled "Shaky clips = stress 😭 Smooth clips = satisfaction 😮‍🔥", with 2.68M views. In Aug 5, "Stop shaky videos with camera tracking in under 30 seconds" got 690K views. The other dozens of posts mostly got a few hundred to a few thousand views, and the official account still has fewer than 6,000 followers.

App Store reviews show who uses it. In Jun 19, a user who calls themselves a TikTok editor, "yvtxr10" (63k followers), wrote: "THE MOST useful app I've ever edited on". Other reviews said "Very good for editing my bikes", "Genuinely made my TikTok's so much better" and "really good for recording videos abt setups, bikes, food". These are young people who shoot cars and bikes for TikTok.

### Where the money comes from: free to build users, tightened this summer

On iOS: $8.99 monthly, $49.99 yearly, or $149.99 one-time. On Android, in-app purchases are priced from $6.99 to $129.99, and ads are shown. The free version can export with ads and no watermark.

The turn came this summer. In Jul 23, a one-star review was titled "All the worthwhile features are gone": "The dual-point tracking and video stabilization that used to be free, even 60fps export, are all Pro now." In August someone complained, "To export one video I have to watch about 10 ads." That shows it has been monetizing seriously these past few months. How much it makes isn't visible from outside. Judging by 411 US ratings over three years, cumulative iOS downloads are likely in the tens of thousands (estimate), so revenue can't be large.

### Why it didn't take off on Android

The Android version went live in Sep 22. Cumulative installs went from 1,579 (10-29) to 2,326 (11-03). A third-party estimate puts it at about 11-06 2,535, with a few dozen to a couple hundred installs a day (Google Play install counts). It has 33 ratings at 4.8 stars. It only reached ranks 174 to 196 on the Poland free video category chart. In Oct 2, the official account's Android launch post got 8,259 views.

The reason is simple: someone else already owned the Android ground. Tracket Motion is built by a single Ukrainian developer, Oleksandr Ksondzyk. It launched on Android first, has 1M+ downloads on Play, and in April 2026 it came to iOS (173 US ratings). It's deeper in features: four-point tracking, perspective tracking, keying, and a color scope.

What matters more is its TikTok playbook. The official account @tracketmotion has 50k followers and nearly a thousand videos, almost all with the same title: "Testing my motion tracking video editor app using video from @某某". They take other people's footage of cars, motorcycles, off-roading and scenery, and demo "look what my app can do with this", tagging the original creator, @original creator. In one week in Oct 28 to Nov 3 they posted a dozen-plus of these, one hitting 11-02 with 187k views and another 71k (TikTok). Zero cost, one person can run it, and the original creators often reshare it.

Motion Track now also reposts spotter footage ("Pagani Utopia 🩵 Edited with Motion Track. Thanks @gian_carspotting"), but each post gets only one or two thousand views. On Android it didn't rely on one hit. It just carried over the old iOS brand. I haven't seen any record of paid campaigns on Meta, TikTok or Google, and the steady install curve doesn't look like heavy paid acquisition (inference).

### Who it's competing with

| Competitors | Scale | How it differs |
|---|---|---|
| Tracket Motion (Ukrainian indie developer) | Play 1M+; iOS US 173 ratings; TikTok 50k followers | Deeper, more general features; launched on Android first, built traffic with a demo video a day |
| CapCut | Play 2B+ installs | Free, has everything, but tracking isn't stable enough |
| Node Video | iOS US store 6,658 ratings | Node-based compositing like AE, high barrier to entry |
| Shaky Video Stabilizer | Play 3.38M installs | Stabilization only, doesn't lock the subject |
| PowerDirector and other all-in-one editors | Hundreds of millions of installs | Stabilization is a side feature |
| Stablify, Stabivio and other stabilization apps launched in the past 2026 years | 0 to 73 ratings | All competing for the "video stabilizer" keyword, all small |

Two apps focused on "locking the subject": one started on iOS, the other on Android, and both have now entered each other's platform. What's left is either CapCut-style all-in-one tools or older stabilization-only utilities.

### If it were you

**C: worth learning from, but not worth copying the product.** The "lock the car center-frame" audience is already held by two apps across both platforms, and CapCut is free as a fallback. Motion Track itself got just over two thousand installs on Android in six weeks, and on iOS it hasn't grown much in three and a half years. The two things really worth taking are turning one pro effect into a one-tap tool for a specific community, and Tracket's zero-cost TikTok demo approach.

- **Good for:** indie developers who can build mobile video tracking themselves (iOS Vision / OpenCV-style tools) and are willing to cut a short video every day. Ideally you're already inside a small community that shoots moving things.

- **Not for:** anyone who wants to build another "car-scene tracking app" and compete head-on with Motion Track and Tracket; anyone who can only wrap existing tools and can't make tracking more stable than CapCut; anyone unwilling to post content every day who is hoping store search for "video stabilizer" will bring traffic on its own (that keyword has already gotten crowded with new apps this year).

- **How to do it:** pick a community nobody is speaking to directly yet, with the same effect and the same three-step operation. Candidates are plane spotters, equestrian, skateboarding and BMX, kids' ball games, and dogs running around (inference; none of these have been validated for demand). Open the first line of copy with that community's language. Keep export free with no watermark to build up users first, and tighten the paywall only after comments show "can't live without it". Keep the one-time purchase option.

- **How to get users:** copy Tracket. In that community's TikTok and Reels, find shaky original footage, make a before-and-after, use a fixed title template, tag the original creator, and post one a day. Motion Track's 2.68M post also used footage borrowed from a car edit account.

- **When to move:** there's no need to rush for a holiday. But Tracket and Motion Track are both expanding into full motion editors. Whichever one first posts a few hits in the community you pick will claim the space, so the sooner the better.

- **Here's what could mean we misread it:** ① Your last 30 demo videos didn't break 50k views. Either the niche is too small, or nobody needs this effect. ② CapCut has made one-tap subject lock solid, and no one in the comments compares you to it anymore. ③ Motion Track on Android hit 50k installs before the end of 2026. That means the car-edit crowd isn't saturated yet, so going head-on might be worth another look.

### Bottom line

This isn't a new product "breaking out" so much as **a 3.5-year-old niche iOS tool finally getting its Android version** . Morning Avocado LLC (a small California studio with a dozen-odd video utilities) shipped Motion Track 2023-04 on iOS, and it picked up 413 ratings (4.7) in the US store off the car-community edit use case: locking a car, motorcycle or bike dead center in frame. 2026-09-22 it hit Google Play right after Ukrainian indie dev **Tracket Motion** (1M+ Android downloads, 2026-04 reverse-entered iOS) had already validated the Android market. The Android version has only about 2,500 installs so far, a few dozen to a couple hundred a day, with flat growth driven mainly by TikTok accounts from its iOS brand and store search. **On Android's numbers, it hasn't broken out yet** . The thing worth watching is this niche and Tracket's playbook, not this app's own breakout.

### 1. Who it is and what the data shows

- Developer Morning Avocado LLC: the privacy policy says “Delaware LLC, located in California” [morningavocado.com/privacy]. The same developer has a dozen-plus other apps on the App Store, including Reacts, Remove Silence, DualCam, ReplayNow, GameEye, Speed Range, RemoveAll, PrivateGPT, DeLive, and VCleaner. Apart from Motion Track, their ratings range from single digits to the twenties [iTunes Search, 2026-11-06]. Motion Track is its only flagship product.

- iOS version (id6447152460): launched 2023-04-09, with 413 US ratings and a 4.75 average [iTunes Lookup 2026-11-06]; Australia 220, Sweden 83, Netherlands 74, Germany 52, Norway 39 [appstore library app_profile]. It was previously called “Motion Track: Follow a Subject” (the link in a Reddit r/fcpx thread) and is now Video Stabilizer, with the subtitle “Slow Mo, Speed Ramp, FX Editor.” iOS pricing: $8.99/month, $49.99/year, $149.99 one-time purchase [apps.apple.com]. Updates are frequent: 6.19 (7-30) to 6.44 (11-05), 25 versions in three months, nearly one every 3 days [App Store version history].

- Ratings have grown slowly: in Australia, 10-28 to 11-06 rose from 215 to 220; in Sweden, 80 to 83 [appstore library app_day]. Its best rank on the iOS Photo & Video free chart by country was #20 in Finland, #34 in Sweden, and #57 in Norway; it never made the top 150 in a major market [appstore library].

- Android version: listed 2026-09-22, in the VIDEO_PLAYERS category; cumulative installs 1,579 (10-29) → 2,326 (11-03) [googleplay library app_snap]; AppstoreSpy estimates 10-19 at 702, 10-26 at 1,463, and 11-06 at 2,535, roughly 40–220 per day [googleplay library app_day_ext]. 11-03 rating 33, 4.8 average. It has only charted in Poland's Video Players & Editors free chart, at ranks 174–196 [googleplay library chart_rank]. In-app purchases on Play run $6.99–$129.99, with ads.

- I couldn't find a source for the data card's “iOS 50k+ downloads”; **unverified** . Based on 413 US ratings plus ratings from other countries, cumulative global downloads in the tens of thousands are plausible.

### 2. Competitors

| Competitors | Platform | Launched | Scale | How it differs from Motion Track |
|---|---|---|---|---|
| Tracket Motion: Video Editor (Oleksandr Ksondzyk, Ukrainian indie developer) | Android / iOS | Android about 2024; iOS 2026-04-15 | Play 1M+ downloads; iOS US store 173 ratings; TikTok @tracketmotion 50k followers, 1.79M likes, 967 videos | More “professional” features: 4-point tracking, perspective tracking, keying, color scopes; positioned as a general tracking editor, not just for cars. It launched on Android first and is the Android template for this niche. Motion Track is the reverse: iOS first, Android added later. |
| CapCut (ByteDance) | All platforms | 2020 | Play 2.06B installs | Has stabilization and tracking, but tracking quality is often criticized (Reddit r/VideoEditing); Motion Track's App Store reviews include an editor saying its tracking beats CapCut's |
| Node Video | iOS | 2020 | US store rating 6,658 | Leans toward AE-style node compositing, high barrier to entry |
| Shaky Video Stabilizer(KallosSoft) | Android (2026-03 on iOS) | 2020 | Play 3.38M installs | Stabilization only, no “subject locking” |
| stabcam, Emulsio, Gyroflow, etc. | iOS | 2011–2023 | Tens to four hundred ratings in the US store | Stabilization only |
| PowerDirector / ActionDirector(CyberLink) | Android | 2014 / 2016 | 144M / 18.6M installs | Stabilization included as a feature in an all-in-one editor |
| Newly emerged small stabilization apps (Stablify, Stabivio, Shaky Video Stabilize) | iOS | 2026-01 to 10 | 0–73 ratings | Chasing the “video stabilizer” search term |
| Desktop: After Effects and DaVinci Resolve tracking / stabilization | Desktop | — | — | Professional, but not usable on a phone |

### 3. Where users came from (growth tactics)

1. **Official TikTok account @motiontrackapp (verified)** : 5,935 followers, 70k likes, 80 videos. The hits are all before-and-after tutorials from the iOS era: the “Shaky clips = stress…” video got 2.69M views (4-06), another 8-05 got 690k, and another 8-16 got 290k [TikHub]. The recent routine approach is **reposting car-spotter footage** (“BMW M5 💙 Edited with Motion Track. Thanks @csl_spotting”), each getting only a few hundred to a few thousand views. The Android launch announcement posted by 10-02 got only 8,259 views. This shows the Android version didn't take off on a single hit; it just carried over the small brand built on iOS.

2. **Organic car-scene UGC (verified, small scale)** : @pbrss2026 “Finally, a good tracking app!” 52k views; @_edward_cls55_ and @blv.zr, car-edit accounts under 1k followers, tag @Motion Track in their videos [TikHub]. An App Store review from a TikTok editor with 63k followers (yvtxr10) calls it “THE MOST useful app I’ve ever edited on.”

3. **Store search / ASO (inferred)** : on iOS it was renamed from “Follow a Subject” to “Video Stabilizer,” with local spellings per country (Stabilise / Stabiliser / Stabilisieren), targeting the broad term “video stabilizer”; the Android listing uses the identical title. The website motiontrackapp.com has SEO tutorial pages (“How to lock an object in place in a video,” “orbit shot”).

4. **Paid acquisition: none found** . Neither it nor Morning Avocado appears in the metaads, tiktokads, or googleads libraries (these only track a watchlist of products, so absence doesn't mean no spending). Judging from the steady tens-to-hundreds of daily installs, it doesn't look like large-scale paid buying.

5. Media, X, Reddit: x-radar shows no relevant discussion in the past 90 days; Reddit has only one r/fcpx reply recommending it [Jina search]. No media coverage.

### 4. Why it exists and why people pay

- **The niche is narrow but the need is real** : car spotters (people filming supercars at the roadside), motorcycle, mountain bike, and plane spotters shoot on phones, where footage shakes and the subject moves. They want the edit look of a car locked in the center of the frame while the background moves. That effect used to require After Effects, and CapCut's tracking wasn't stable enough. Motion Track packages it into three steps: tap a point, track, and use blur to fill the edges.

- **Positioning language is the differentiator** : the first line of the description is “Lock a car, scooter or mountain bike steady in frame, parked at a meet or flat out on the road,” speaking directly to car enthusiasts; Tracket describes itself as a “general tracking editor.”

- **On-device processing, no uploads, no sign-up** : the website and description both highlight this prominently.

- **Payment structure** : the free version exports with ads; advanced stabilization, dual-point tracking, and 60fps export require Pro. An App Store review complains that “features that used to be free are now locked” (7-23), suggesting the paywall was tightened in the summer of 2026 and monetization became serious.

- **Iteration speed** : 25 versions in three months, continually adding subtitles, color grading, masks, 41 effects, and optical-flow motion blur. It's shifting from a “tracking tool” into a complete motion-focused editor, which increasingly resembles Tracket's path.

### 5. Differentiation, and whether that's why it broke out

- Versus Tracket: Tracket has greater feature depth (4-point and perspective tracking); Motion Track wins on its “built for cars” positioning and a simpler “three taps to lock” pitch.

- Versus CapCut: tracking is more stable, and it's built specifically for one effect.

- But on Android, this differentiation **hasn't turned into growth yet** : Tracket used 967 videos titled "Testing my motion tracking video editor app using video from @xxx" to rack up multiple views in the millions to five million, and picked up 1M+ installs. Motion Track only got about 2,500 installs in 6 weeks on Android. What actually made it stick on iOS was locking in the "lock subject" effect 2023 years early, plus a few viral TikTok tutorials. The Android version is just filling the gap.

### 6. How many people know about it / follow the trend

- Visibility: **almost nobody knows about it** . No public revenue, no coverage from media or big X accounts, and the official TikTok account has under 6,000 followers. Only a small circle of car edit creators uses it.

- Copycats: the main players are Tracket (it came earlier and is bigger, so it's not a copycat of Motion Track; the two are moving into each other's platforms). 2026 saw a batch of "Video Stabilizer" micro-apps (Stablify 10-04, Stabivio 9-28, Shaky Video Stabilize 1-12) all fighting over the same search term, all small.

### 7. What others can borrow

- **Cut a professional effect (AE tracking + stabilization) into a one-tap tool for a vertical audience** , with copy that speaks that audience's language (cars, meets, spotters).

- **Tracket's TikTok playbook is worth copying** : demo "my app can do this" using other people's footage, one post a day, a fixed title template, tag the original creator. Some posts hit niche communities (off-road, ATV, football) and took off. It's nearly free and one person can run it.

- Validate on one platform, then move to another: Tracket went Android → iOS, Motion Track went iOS → Android, and both are going after each other's turf.

### 8. Uncertain

- iOS global lifetime downloads and revenue (the "50k+" on the data card has no source).

- Whether Android has any paid acquisition (the ad library doesn't cover it).

- 33 ratings / 2,300 installs (about 1.4%) is high. There may be an in-app prompt for rating, unverified.

- Tracket's exact install count and curve on Play (not in our database; only the store-page band "1M+").
