### 1/5 — Took up an insane & weird amount of energy and drained my battery

*2026-06-04*

This app took up a crazy amount of energy from my computer. Either it has a bug or it’s sus. It took like 4000 energy impact, while my google chrome (with a ton of tabs open) was less than 200. Idk, I’d avoid.

### 5/5 — Passed my midterm

*2026-05-18*

got this a week before the midterm it was looking rough. not only was this kinda fun but it was actually helpful. The only thing I didn’t like is my prof uses “aspartate” and “glutamate” while the app uses aspartic acid and glutamic acid.

### 5/5 — Goatesque 🙏🏻🙏🏻

### 5/5 — Amazing

*2026-02-08, version 1.6*

this is seriously helping me for the MCAT. Great reactive interface as well. Paid for the ad free version just to support. Thank you so much!

So helpful for cramming, helped me memorize all in one day!! Practice every now and then and it keeps the knowledge fresh

### 5/5 — Good tool

*2026-02-03, version 1.6*

I just wish it kept a record of all my times so I could see it

### 5/5 — Top

*2026-02-02*

So eine tolle app!! die beste

### 5/5 — Only one critic

*2026-01-29*

I really wish there was an option to do fill in the blank. After a while the multiple choice format becomes way too easy and a option to put in answers as fill in the blank would not only make it more difficult but aid in studying
