### 1/5 — DON’T WASTE YOUR TIME

*2026-01-12*

I was loving this app to study for the CPA exam. The actual app works great for making cards and is easy to use. However after having a great time, my two essential decks were randomly deleted and disappeared from my phone. I hope to save others from this disaster.

### 1/5 — Horrible, don’t waste your time

*2025-04-14*

I have lost all my progress and flash cards after adding them meticulously. The developers did not respond to my email and there is no support for the app. It generally is very laggy and your whole deck might be deleted.

### 3/5 — Can only take pictures.

*2025-05-26*

Can’t upload images.

### 5/5 — Best studying app

*2026-02-09*

This is the best studying app I’ve ever used. I’m a college freshman and I had midterms last week and using this was very advantageous to studying.  I used this app throughout different topics and ended up happy with my scores!

### 5/5 — awesome app aced all my exams
