### 3/5 — Unnecessary information

*2026-05-04*

The app is easy to use and I would use it if they didn’t have you study for information that you don’t don’t to know. Wasted my time learning about things I didn’t even need to know for the exam.

### 5/5 — Free and very helpful

*2026-04-27*

When I first got the app I thought it was have a subscription or ads, but it had neither. This is very surprising for the amount of content that they have and how easy it is to use the UI. Sadly they’re missing about half the AP’s and the app has a hard time sinking data. Honestly tho, it’s a great app and so far has been great to use for the Ap exams. I highly recommend it, good job devs on making this and thank you for making it free (like genuinely thank you, you saved me soo much study time)

### 5/5 — Love it!

*2026-04-24*

One of the best apps I’ve used for studying, has zero ads and isn’t promoting a special subscription every couple minutes. Genuinely amazing, contains immense amounts of study material for all sorts of ap classes! 10/10 definitely recommend

### 5/5 — Peak

*2026-04-22*

This app is peak for ap exam review i got a 5 in AP world cuz of it and its all free

### 5/5 — Noice

*2026-02-18*

It’s pretty good, it has practice questions to go with study guides. No ads

### 4/5 — Other apes

*2026-02-18*

It’s a really good website to study from for the apes, but it will be even a better app if the other apes were open!!! Because I am taking 2 other apes that are on the requested side and deeply wishes if they get to open as soon as possible!!!!! PLEASE

**Developer response:** Thank you so much! We’re actively working on opening more AP subjects and rolling them out soon. We’re expanding as fast as we can while keeping everything high quality. Stay tuned, more APs are on the way.

### 5/5 — Amazing app

*2026-02-11*

Completely free with no ads and is an amazing way to study for AP classes.

### 5/5 — Please have the definitions on the app too

*2026-01-21*

Please include the definitions on the app instead of just the website.

### 5/5 — good app

*2026-01-06*

Have been using it for a while, really helpful for ap psych!

### 5/5 — Explain feature

*2025-11-19*

Great app just wish the explain feature was in the app like on the site

**Developer response:** Thanks so much for the feedback, we really appreciate it! We’ve added the Explain feature to the app in a recent update, so you should now have the same experience as on the site. If you have any other feature requests or ideas, we’re always listening!
