### 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 — Outstanding

*2019-12-20*

I love this app. It’s very useful.

### 3/5 — Not useful for engineers

*2019-11-14, version 2.2*

Easy to use but lacks many unit conversions needed in engineering like pressure, torque, force, energy. Still the best free unit converter found for Apple but much better are available for android phones

### 3/5 — It’s ok!

*2019-06-27*

I used convert bot until it's demise. This is ok. Usable but not very smooth. The free version does not encourage me to buy the upgrade unfortunately.

### 5/5 — Has anyone gotten this app to do anything whatsoever?

*2019-05-02*

Just wondering.

### 2/5 — Widget is broken

*2019-03-24*

The widget will not change units of measurement. The arrows to cycle through the options don’t do anything. This is the entire reason I got it. 
Only 2 stars because it does offer a lot but incredibly hard to use. Made the app 10 times more complex than it should be. We’re converting units, not flying a spaceship. Way too much going on

### 5/5 — Excelente

*2019-03-19, version 2.2*

Excelente aplicación tienes desde lo más simple hasta lo más específico en medidas.

### 5/5 — Simple and logical interface

*2019-02-02*

Does the conversion for different power ratings well. It may be a bit confusing the first time you use it but after 10 seconds playing around it is a good interface. Helpful if looking at imperial or industry power units from the USA to metric standards in Europe and Australia.

### 4/5 — Utilitaire

*2018-12-31*

Je viens d’acheter cette application et elle me convient très bien pour mes activités de tir par les conversions grammes /grains et millimètres /pouces

### 5/5 — Superb

*2018-12-06*

Very useful and suitable for school our teacher said its very good for mathematics 👍🏾💪🏾

### 5/5 — Good app

*2018-12-03*

Useful app

### 5/5 — Liked the older version better, but . .

*2018-11-24*

I had used a previous version for a long time and loved it. This version does way more, but it takes longer to spin through the different unit selections since there are so many. Minor complaint, extremely useful tool. Thanks

### 2/5 — Pretty to look at

*2018-11-18*

But this isn’t a painting so beyond looking at it you need to use it. Often in a hurry. The UI is too fiddly and sensitive in a addition to being busy. 

I was using this app to evaluate the infinite version so I’m not looking for necessarily a free or cheap app. 

The functionality is there but the entire interface needs to be overhauled to make it easier and faster to use.

### 5/5 — Muito útil!!!

*2018-11-14*

App com grande variedade de unidades e bem simples.

## Most critical reviews (10 lowest-rated)

### 1/5 — Not good

*2026-06-01*

Just an ad for the paid app, does not work

### 1/5 — VA <> W

*2019-09-05*

Le Watt n'est pas la même chose que le Volt-Ampere. Par exemple un onduleur de 700VA peut fournir 400W.

### 1/5 — How do you even use it?

*2019-04-20*

Not user friendly. You have to figure out this wheel of units and then somehow, I guess, you’re able to enter numbers. I was able to enter the number 1 and no more.

### 1/5 — Unintuitive

*2019-01-10*

This app tries to imitate an older app called ConvertBot (Which was abandoned by the dev and no longer compatible with the latest iOS) however it imitates it very poorly and is very unintuitive to use.

Don’t bother with this app, just get a normal converter app.

### 1/5 — Interface poor

*2018-11-26*

Very comprehensive but interface poor.

### 1/5 — too hard to use

*2018-03-22*

I find this app to be clumsy. I do not need to convert internet speeds in my widget. Can’t seem to figure out how to change settings for it, and overall it seems the developers were more concerned with making it look slick than with how easy it was to use.

### 1/5 — Неудачное приложение.

*2017-11-15*

Валюта не обновлялась как минимум годы.

### 1/5 — Terrible

*2017-09-23*

Interface is terrible and unusable.

### 1/5 — Not ConvertBot

*2017-09-21*

Clunky. Can't edit the units to simply. Speed does have Knots.

### 1/5 — Dod

*2017-01-01*

Useless App waist of time

## Most praised reviews (10 highest-rated)

### 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。

### 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!

### 5/5 — Great

*2020-08-08*

it’s fantastic ,.  5stars UI

### 5/5 — Fantastic

*2020-05-30*

This converter application is really great. I’ve tried several, but this one is “head and shoulders” above any of the other ones!!

### 5/5 — If you work with math,  this is the most complete Bundle you should need.

*2020-01-21*

I’m a retired Structural Engineering consultant and I used a Hewlett-Packard calculator for all of my needs. I’m used to Reverse Polish Notation (although I have not found out if you can use RPN on this calculator). I like the way it sets up Algebraic formulas. It does take a small learning curve but it was well worth it. I understand how it can be overwhelming but it covers my total needs at a reasonable price. Five Stars and worth it.
