### 4/5 — Funktionalität 1a!

*2024-01-08*

Sehr schön umgesetzt. Bitte die UI am iPhone 15 anpassen, danke.

### 4/5 — Leider keine Optische Anpassung

*2021-11-20*

Die App scheint nicht an neue IOS Versionen bzw. Geräte angepasst zu werden. Sieht sehr verzerrt aus und nicht wie auf den Bildern… Funktion ist gut aber das Design sollte dringend angepasst werden. Dann gibts auch 5 Sterne…

### 4/5 — Great converter with calculator integration

*2021-09-26, version 7.2*

Love it. I gave 4 stars rather than 5 only because it always launches with currency conversion, and wants you to wait while it downloads current rates.  I almost never use it for that.

### 5/5 — Great Product

*2020-10-26, version 7.1*

This App is very useful and handy when you need a quick conversion.

### 5/5 — You’ll convert, too!

*2020-07-19, version 7.1*

I use this almost every day and it has never failed. Thank you!

### 5/5 — Standard App

*2020-07-14*

Diese App tut einfach und gut, was der Titel verspricht. Gehört als Standard auf jedes IPhone.

### 5/5 — Great converter app

*2019-12-20, version 6.8*

It has so many options, I've never needed something it didn't have. It's quick and clear. I’ve never seen glitches or issues. Good job!

### 5/5 — Tolle App

*2019-07-19*

Die verschiedensten Einheiten einfach umrechnen - funktioniert super und bisher ohne Werbung. 
Von mir eine klare Empfehlung 👍🏼

### 5/5 — tolles Umrechnungstool

*2019-04-29*

Damit kann so ziemlich jede Größe umgerechnet werden.
Das geschieht einfach und direkt.
Bei physikalischen Größen würde ich mir die informative Angabe einer Formel wünschen.

### 5/5 — Hammer 👍👍👍👍👍

*2018-10-23*

Klasse, jetzt auch mit iPhone X Umsetzung. 

Und hammer umgesetzt ist auch die Apple Watch. So perfekt und dabei einfachst zu bedienen. 

>> ein toller Programmierer !

### 5/5 — I use it a lot

*2017-12-16, version 5.9*

It’s my go to app for converting almost anything.  Very Easy to use

### 5/5 — Macht, was sie soll

*2017-10-23*

Funktioniert einwandfrei, auch im Bereich Finanzen, umfangreich in den Angeboten. Habe einige Umrechnungskurs-Apps getestet, diese ist von den mir bekannten die beste.

### 3/5 — Très bien mais...

*2017-08-18*

On ne peut ajouter nos propres devises de nos choix type FRF.

**Developer response:** Thanks for your feedback. We will consider adding legacy currencies (becoming EURO) in a next update.

### 5/5 — Very Versatile Converter

*2017-08-03, version 5.5*

Had used a different converter until recently, but that app stopped updating exchange rates, which I need for my trips abroad.

I do need other (physics and engineering) conversions too and this app was pretty much the only one that met my various requirements. 

Not much to change really, the only improvement I would ask for is being able to enter values through a keyboard and not only through the touchscreen.

*2019-07-18*

Application nulle

### 1/5 — Friendliness

*2018-05-20, version 6.3*

The font size is so small that it can hardly be recognized. It has wasted space and restricted the the units that can be seen at once on the screen. Two thumbs down.

### 1/5 — Très déçu

*2012-09-19*

Je suis vraiment déçu car je l'ai acheter exprès pour convertir des pesos de république dominicaine.. Et cette devise n'est pas disponible et apperrement impossible de la télécharger sur l'app'!! Donc 1,5€ dans le vent, M si ce n'est que ça, et bien je donne ZERO a cet App'!!!

### 1/5 — Mr.

*2012-07-06, version 3.0.1*

I was surprised to learn that an acre was 1075+ sq. ft. Always thought it to be in excess of 43,000 sq. ft.
Format and ease of use was good but now I have to question accurac

### 1/5 — Pretty useless

*2011-01-16, version 1.1*

No Volume or Area conversions at all!
Rest it does have are very limited.
Deleted!

### 2/5 — ⭐️⭐️

*2025-08-03*

So ist eigentlich sehr hilfreiche App nur Menü-Auswahl rad Schriften sind zu klein.

*2022-02-16, version 7.4*

### 2/5 — Erreur devises

*2015-06-25*

Bonne appli mais problème de dépassement de capacité en conversion de devises, donc inutilisable pour cela. Demande de correction en attente.

### 3/5 — Es fällt noch Zeit <-> Frequenz

*2020-05-05*

Nützliches Werkzeug. Schade dass nicht weiterentwickelt ☹️

### 5/5 — Klasse

*2023-07-26*

Benutze ich seit langem und immer wieder gerne. Mir gefällt vor allem das Design.

### 5/5 — iConvert

*2023-06-17, version 7.6*

Very good, very hard to customise edit settings. I would like to move the Calculator to the top, so that when ever I want t calculate something it’s there, tend use calc the most.
For my iPhone no problems. Very good.  How can I do the same on my iPad?  Got it. Got it. Thanks and a thousand pardons. Very good. XXXXX👌.on the iPhone I can only change the 4 on the top tabar. ?

### 5/5 — New Conversion

*2023-01-10, version 7.5*

Why is there no feature in iConvert to convert number systems - e.g. binary to decimal?

### 5/5 — Eine meiner Standard-Apps

*2022-03-31*

Seit vielen Jahren immer aktuell! Ich liebe sie❤️

### 5/5 — Sehr

*2022-03-29*

zufrieden damit

### 5/5 — Great app all around!

*2021-08-20, version 7.2*

I use it frequently in my work for converting measures from scientific to English and back. So far it has covered every conversion unit I have needed.

It is also quite useful for converting currencies while traveling and when preparing international quotes. When others in the room are guessing or “guesstimating” it affords me the opportunity to be the smart aleck in the room by having the exact exchange rate for that day.

I must say that I found life much more difficult without it.
