## Most critical reviews (4 lowest-rated)

### 2/5 — Well, you asked for it

*2022-07-17*

Asking me to review the app EVERY time I open it can have unintended consequences.

### 4/5 — Great Game

*2019-09-15*

This game is super fun. It kinda reminds me of Sudoku. It’s a bit confusing at first and the directions are a bit unclear but overall, it is still super fun.

### 5/5 — Great app

*2024-04-28*

I really enjoy this app. It’s fun enough relax but challenging enough to improve mental dexterity.

### 5/5 — Superb game !!!

*2019-06-12*

Calculus is a superb game.   However it is quite hard at the beginning.     
Never saw such a game.    Good work !!   Keep it up !!
