### 5/5 — Life saver

*2026-05-03*

Absolutely a life saver

### 4/5 — Was amazing, now is ok.

*2026-01-15*

The first time I used this app, it helps me pass pre calculus. It was simple, just plug in the numbers for the unit circle. But I think now it’s been simplified a little too much. Now you put all of the match into one box so you can see any of the of match except for the one you just put in it, which is pretty annoying. Also it glitches now to, you put a match in to a box, but then it will duplicate itself to where now its in the box on the unit I circle but also on the bottom where all of the unmatched cards are. Meaning you complete the unit I circle but still have match cards unmatched, making it so when you go to check your answer it will tell you “ Not quite yet, # wrong but still # not placed. Which is also very annoying.

**Developer response:** Thank you for your feedback. I will take a look and submit an update in the near future.

### 5/5 — LIFECHANGING

*2023-05-09*

This app changed my life and helped me pass my tests!!
