### 5/5 — Simply perfect for the travelling engineer!

*2026-05-27, version 3.1*

Simple. Easy. Nice. Reliable. Handy. That says it all. With just 2.2MB!

LOOONG time user. THANK YOU for this phantastic, lovely app! 😀🫶🏻

1 minor thing: lowest currency can‘t be selected (iPhone 15/iOS26.5), also on previous version.

### 5/5 — Perfecta!!

*2025-11-06, version 3.1*

La llevo usando años… Su diseño es lo mejor, es sencilla y cómoda de usar. 
Gracias!!!

### 1/5 — 為替が更新されてない

*2025-06-17, version 3.0*

6年間放置されてる

### 1/5 — Currency

*2024-01-24, version 3.0*

The app is not updating exchange rates.

### 5/5 — Great App

*2023-03-11, version 3.0*

Super handy I use often

### 1/5 — Währungsrechner geht nicht mehr

*2022-07-13, version 3.0*

App ist an sich super, jedoch stimmen mittlerweile die Umrechnungsfaktoren bei den Währungen nicht mehr. Es steht zwar immer das aktuelle Datum, aber ein komplett falscher Wechselkurs dort. So fällt für mich ein großer Nutzen weg, schade!

### 1/5 — Not accurate at all

*2021-12-27, version 3.0*

As of December 26 you are saying that the exchange rates are 

For 1 Canadian Dollars

From 

CAD to USD 

0,97$

It is totally wrong! 

It’s like 0,20$ OVER.

Very disappointed.

### 1/5 — DO NOT PURCHASE!

*2021-09-08, version 3.0*

Very unresponsive team. I have been asking for a simple addition to their currency list and have been told that it would be added. Here we are a few years later and still nothing has happened.

### 3/5 — Great app but currency stop working

*2021-06-04, version 3.0*

I love the app, design, but the currency does not work.

### 1/5 — Hatalı Çeviri

*2021-05-20, version 3.0*

Program çevirileri doğru yapmıyor!!! Acil güncelleme gerekiyor.
