### 2/5 — What is going on with the wrong wrong?

*2026-06-17*

So you can make it so that it doesn’t take so much time when you press the run code

### 1/5 — No interaction. Just text

*2025-11-19*

I don’t see the point. How do you learn by only reading a bunch of text and a code example, you don’t even break down the code.

### 5/5 — The best Python learning app!

*2025-10-25*

Such a fun and intuitive way to learn Python! The lessons are clear, hands-on, and work perfectly offline — great for learning anywhere. The interface is smooth, minimal, and beautifully designed. I’ve tried many coding apps, but this one truly stands out for how thoughtfully it’s built. Highly recommended!

### 1/5 — Looks great but unusable

*2025-06-06*

Plenty of storage and working internet on my devices but I keep getting an error claiming that is not the case.  I’m unable to download any lessons.

### 5/5 — Excellent

*2025-06-06*

Literally one of the best apps out there to learn not only Python, but Machine Learning and other stuff. I love it!

### 5/5 — Absolutely Wonderful For Beginners!

*2025-04-14*

Wonderfully designed. Easy to understand format and instructions. Very easy to follow with examples and explanations. Highly recommend! Some classes cost a little money, none that I have seen cost more than $2.99. That $2.99 gets you a full course of classes that instructs you on entire concepts within and about python coding. Companies need to make a little money for what they create and for the quality of this product I think the price that they are asking for, for these courses, is incredibly cheap.

### 5/5 — Crashes in iPadOS 18 (fixed)

*2025-04-02*

The app is a very good source to learn Python offline. However it starts crashing at the launch since IPadOS 18. The fix is to uninstall the app completely, then reinstall it.

**Developer response:** This likely happens because of restoring from backup—please, delete the app from device and reinstall again from the App Store. This will be fixed in the next release; apologies for inconvenience meanwhile. 😔

### 2/5 — Crashes in iPadOS 18

*2024-12-25*

The app is a very good source to learn Python offline. However it starts crashing at the launch since IPadOS 18. There is no update for a very long time. It does not seem this app is well maintained.

### 5/5 — Excellent for the beginner or the prodigal programmer

*2024-08-23*

I’m using Tinkerstellar to relearn Python as I’m going into graduate school, and so far it has proven to be an absolutely invaluable resource. Tutorials are lucid and clear, and the breadth of topics available is astounding. Absolutely worth the time and money.

### 1/5 — Crashes on opening on M4 IPad Pro

*2024-06-21*

Keeps crashing on new M4 IPad Pro

**Developer response:** This likely happens because of restoring from backup—please, delete the app from device and reinstall again from the App Store. This will be fixed in the next release; apologies for inconvenience meanwhile. 😔
