### 1/5 — Not good

*2026-06-01*

Just an ad for the paid app, does not work

### 5/5 — 有用

*2025-12-12*

我觉的很有必要

### 5/5 — GOOD

*2025-12-05*

计算和换算剪得好多数学上没有烦恼了。

### 3/5 — Work well enough, but…

*2023-09-19*

UI is a bit strange. I’d trade all the cuteness for simplicity.

### 4/5 — Bien !

*2023-03-11*

Bien = pratique et amusant à utiliser. 
 
Il faut juste comprendre d’abord que 
pour accéder à toutes les unités proposées, il faut faire tourner la roue. ⚙️ 
 
idées d’amélioration : 
 
1) Ce serait cool d’avoir le choix entre les divers systèmes existants de séparation des chiffres des nombres : 
par 2 ou par 3, et par point ou virgule ou apostrophe. 
 
2) Ce serait sympa aussi d’avoir le choix entre diverses couleurs pour le thème de l’app.

### 5/5 — The Best One

*2022-05-10*

Of all converters I have known, this is doubtlessly the best. Easy to manage, accurate, graphically attractive…

### 5/5 — Ergonomic

*2021-02-19*

One of the BEST concepts I’ve seen, functionality is SUPERB, two issues though:

Calculator buttons keys could be round
The ‘back’ arrow key could be bigger

...but these are small issues, if rectified, I’d probably buy the upgrade

### 5/5 — A 1

*2020-11-25*

Vraiment simple, rapide et nice look!

### 5/5 — Unit converter

*2020-08-27*

Useful with engoiment

### 5/5 — Awesome app!

*2020-08-17*

The app looks so futuristic and feels natural to use so why has the development stopped for this app? I’m seeing it hasn’t been updated since 2 years now!
