There's no Pydroid on iPhone, so someone grabbed the name: in 8 days it reached the 53 Developer Tools chart with only a few thousand downloads

In 2026 Oct 29, a free app called "Pydroid 3 - IDE for Python" showed up on the App Store. Pydroid 3 on Android is the first Python tool many students install, with about 17.9M installs, but it never had an iOS version. This iOS app wasn't made by the original developer. An indie dev named THOMAS PEREZ registered the name first, put a plain Python editor behind it, and monetized with ads. 8 days later it ranked #1 on the Developer Tools free chart in Algeria, and it had charted in 53 countries. Here's how it got there, how small the numbers actually are, which part is worth copying, and which part isn't.

A search term nobody had claimed in five years

The Android original, Pydroid 3, is developed by a company called Lider Soft KZ (IIEC). On Google Play it has about 17.9M installs and 92K ratings, and in the last 7 days it added about 100K installs (Google Play, 11-06). In Nigeria, Algeria and Pakistan, where Android dominates, many students learn Python on their phones with it.

The problem is what happens when those people switch to iPhone. From 2020 to 2025, posts like "when is Pydroid coming to iOS" and "is there a free Python IDE for iPhone" kept appearing on Reddit (r/Python and r/learnpython both have several). The most common complaint in the replies is that Python apps on iOS are mostly paid or subscription-based. The original developer never released an iOS version. So for five years, searching "pydroid" on the App Store turned up nothing with that name.

What it did: stuffing the name everywhere

Its store page has almost nothing: version 1.0, no updates since launch, 66.1 MB, English only, free, no in-app purchases. The description is four sentences, "Pydroid 3" appears 5 times, the title is "Pydroid 3 - IDE for Python", and the subtitle is "Pydroid 3: offline Python IDE" (US App Store page, 11-06). The features are syntax highlighting, autocomplete, error hints, a console that supports input(), plotting and sample code. There are dozens of free Python editors on iOS with this same feature set.

The privacy labels list "third-party advertising" and "used to track you: device identifiers", so the money comes from ads. The privacy policy sits on a Google Sites page, and the developer site is a blogspot page that holds only the app-ads.txt file for ads.

As a result, 11-06 ranks #1 for "pydroid" on the US App Store, #3 for "python ide", and #5 for "python", ahead of established apps like Pythonista, Pyto, Mimo and Sololearn (US App Store search, 11-06). Apple's search weights title and subtitle keywords heavily, and this app put the whole brand name in both with no one else competing for it.

How fast it grew versus how small it is

(App Store Developer Tools free chart ranks and ratings across storefronts, recorded daily)

11-06 Best-performing countries: #1 in Algeria, #3 in Nigeria, #6 in Indonesia, #7 in Tunisia, #8 in Ukraine and Bolivia, #10 in Pakistan. These are all markets with lots of Android users and students. People there have seen Pydroid on Android and then search for the name on iPhone (inferred).

Don't be fooled by "53 countries." It has never charted on any country's overall chart. The Developer Tools category has a low bar in small countries: a few dozen downloads a day can get you into the top 10. Globally it has 10 ratings total, 1 in the US store (5 stars), and 1 in Algeria (1 stars). Going by rating counts, that's probably a few hundred to a few thousand downloads (estimate). It only shows ads and has no in-app purchases, so ad revenue from this volume should be tiny.

Where users come from

• App Store search capturing the brand term: confirmed. The search rankings above are the evidence, and this is the main reason it climbed.
• Organic exposure from small-country category charts: confirmed it charted. Charting brings a bit more visibility and a few more downloads.
• TikTok, X, Reddit: nothing found. Searching "pydroid ios" on TikTok returns Android Pydroid tutorials. On X, posts mentioning pydroid in the last 30 days number 0.
• Paid acquisition: none found. An app that only shows ads and earns a few cents per download can't pay back paid user acquisition (inferred: no spend).

This is a batch play, and someone did it earlier and better

THOMAS PEREZ has 3 apps in total, all same-name versions of well-known Android apps: ADV Screen Recorder (listed in June, 20 ratings), Activity Launcher (listed 10-28, the Android original has about 32.5M installs, but iOS can't do this feature at all, 0 ratings), and this Pydroid 3. The approach is obvious: find popular Android tools that don't exist on iOS, register the name first, wrap it in the simplest shell, and see which one takes off.

Someone walked the same path earlier and did it better. Pyroid, published by a developer named "TERMUX LIMITED LIABILITY COMPANY" (Termux is another well-known Android terminal app), listed in Jan 2026 27. It borrows the Pydroid name, borrows the Termux developer name, and its subtitle reads "Pythonista Compiler Coding App", casually riding on Pythonista, the best-known Python app on iOS. But the product is genuinely built: 436 MB, a built-in Python 3.13, preinstalled libraries including NumPy, pandas, Matplotlib, Flask, and Pygame (70 in total), Jupyter notebook support, breakpoint debugging, 11 chapters of lessons and 100 exercises, and an on-device AI tutor. The interface supports 12 languages (US App Store page, 11-06).

Its pricing is worth a look too: no ads at all, and the free editor covers everything, but code can only run 5 times. That's a one-time quota, not 5 runs a day. To keep running, you have to upgrade to Pro, which comes as a weekly subscription, an annual subscription, or a one-time purchase. US store: 101 ratings, 4.6 stars. 11-06 It charted in 91 countries, hit #1 in the Dominica category Top Grossing chart, and landed in the top 11 Top Grossing in the Philippines, Uzbekistan and Ecuador, so it's clearly collecting real money. One review reads "In Iran we can't pay with PayPal, please find another way," which shows people willing to pay have reached very remote markets.

Taken together: Pydroid 3's iOS version is just a name. Pyroid is a name plus a product that can charge money. The former earns pocket change from ads; the latter has reached grossing charts in several countries.

What to take from this and what not to

What's worth learning is the insight: a tool with tens of millions of Android installs and no official iOS version leaves a long-running, unmet search demand on the App Store. Pydroid, Termux, and various Android-only tools all fall into this category. Students and developers switching from Android to iPhone go searching, and when they find nothing they either buy the paid Pythonista or give up.

What you shouldn't copy is using someone else's brand name directly. Apple's rules 4.1 (imitation) and 5.2 (intellectual property) cover exactly this. One complaint from the original author gets the app pulled, and the account can be dragged down with it. That's why people in this space run many accounts with several apps each, so they never bet everything on one app. This approach isn't promoted or written about, so few people know it, but its moat is simply that the original author hasn't complained yet.

If it were you

The bottom line: the demand for "free Python on iPhone" is real and has been there all along. But the "borrowed name + ads" version earns little and can be pulled at any time, so it's not worth copying. The version worth building is Pyroid's, but it already holds that spot. You'd have to do it better than them, or pick a different direction.

Who it suits: indie developers who can package CPython or Pyodide into an iOS app and are willing to put real effort into teaching content; people who've worked the student market and understand payment habits in India, Southeast Asia, North Africa, and Latin America.

Who it doesn't suit: people who want to wrap a shell, change the name, and ship. Two players are already fighting over this brand term. Squeezing in now only makes the traffic smaller, and the takedown risk is no lower.

How to do it:

• Don't use someone else's trademark in the name. Use generic terms in the title (Python, IDE, offline, compiler) and describe the "Android-style experience" in the description and screenshots. Search ranking will be slower to build, but it won't go to zero after one complaint.
• Borrow Pyroid's monetization structure: no ads, use a "run count" to limit free users, then offer weekly, annual, and one-time purchase options.
• Go where Pyroid falls short: payment difficulty in the student market (the Iranian user in the reviews couldn't pay at all). Try regional pricing or a cheap one-time purchase. Localize for university courses and exam question banks (French for North Africa, Spanish for Latin America, Indonesian). Build an "import projects from Android Pydroid" feature that helps people migrate.
• The same insight applies to other "exists on Android, missing on iOS" developer tools, such as terminals, Arduino/microcontroller programming, and C/C++ compilers. First check whether anyone has seriously built those keywords on the App Store.

How to get users: App Store search (python, python ide, python offline, python compiler, plus how it's said in each language), plus the low-bar organic exposure from small-country Developer Tools charts. Old Reddit threads asking "is there Pydroid for iPhone?" keep bringing people in, and answering in them can bring some users too. This group has weak willingness to pay, so paid acquisition will most likely not pay off.

How long the window stays open: there's no hard deadline, but two things would close it: the original author releasing their own iOS version, or the original author starting to file complaints against same-name apps. Whichever comes first narrows this path considerably. Also, every extra month Pyroid accumulates ratings makes it harder for latecomers to catch up in search.

What would show the read was wrong: if this Pydroid 3 iOS version is still at a few dozen ratings and its chart position keeps slipping after a month or two, the traffic from the borrowed name is capped at that level. If Pyroid's grossing rank also declines, it means "learning Python on iPhone" is smaller than it looks, and most students still go back to Android or use a computer.
