### 5/5 — correction needed

*2025-11-23, version 6.3.0*

Ten's complement practice lesson have incorrect answers.

### 5/5 — Insightful tips

*2025-07-31, version 6.3.0*

Lots of fun techniques to make mental arithmetic a bit easier. Would love to see more tricks added in the future.

### 1/5 — Broken Game Mechanics

*2025-01-15, version 6.3.0*

When you play it doesn’t tell you if you got the question right or wrong. 

And in the timed games it always says you got the last question wrong because the question wasn’t answered. The last question in a timed game can never be answered - therefore it should not be counted in the total.

### 5/5 — Quase perfeito!

*2025-01-12, version 6.3.0*

Falta o modo escuro e outros idiomas, como o português. No resto é excelente!

### 5/5 — Great app

*2024-08-12, version 6.3.0*

No nonsense, bite sized concepts with huge potential to improve your calculation skill.  This app was clearly designed by a minimalist. It has everything you need and expect with no time wasters or fillers.

### 5/5 — Pretty Incredible.

*2024-05-22, version 6.3.0*

### 5/5 — Great workout

*2023-03-20, version 6.3.0*

Excellent lessons followed by plenty of practice. Great work, thanks.

### 3/5 — Safe?

*2023-02-06*

I bought this app years ago but I quickly deleted it because I couldn’t figure it out. I was just thinking about installing it again just in case there’s a chance I would do better. However, before I install any old apps, I always try to visit the developer’s website first. This one doesn’t seem to be safe because I don’t see it being locked. I’m now having second thoughts. Is there anyone that can help? If not, I’ll just let this app stay where it is and hope that some one notices.

### 5/5 — Expands the ability to do basis math fast.  Lots of tricks.

*2023-01-09, version 6.3.0*

Real deal.

### 5/5 — Hopeful

*2021-12-11, version 6.2.0*

I’m practically relearning math to make it fun for my grandson
