### 2/5 — Multiplikation und Division fehlen.

*2026-05-31*

Es ist durchaus möglich, dass man wie bei einem normalen Taschenrechner Uhrzeiten auch mal mit einer Zahl malnehmen oder teilen muss.
Es gibt keine Buttons für  Multiplikation und Division. Daher ist das nicht möglich.
Das sollte unbedingt noch hinzugefügt werden.

### 5/5 — Super-Praktisch

*2025-07-02*

Wer viel mit Zeitspannen und Uhrzeiten rechnen muss, wird dieses Tool lieben. Ich benutze es sowohl privat für die Backplanung (Teigruhezeiten etc), als auch im Job für Arbeits- und Ruhezeiten.

### 5/5 — Well done

*2024-12-16*

Great App to calculate time spans.

### 5/5 — Time calc made easy

*2022-12-18*

This is an example, 2:59 + 0:01 = 3:00 not 2:60 That’s what makes this calculator great for doing long calculations. Great for converting from time to decimal format when doing payroll. Also has duration calculation.

### 2/5 — Not quite what I need

*2022-10-05*

I was looking for an app that allows for dividing and multiplying time and this isn’t it. Hoping I can get a refund? I purchased too quickly in hopes that a for-fee app would provide additional functionality.

### 5/5 — Perfekter Arbeitszeitrechner

*2022-01-28*

Ich brauche für meine tägliche Einsatz Bestätigung einen Dezimal-Arbeitszeit-Rechner, um schnell und einfach meine Einsatzstunden in die Tabelle eintragen zu können. Jetzt habe ich nach langer Suche endlich die richtige App gefunden! Alles ist in der App übersichtlich, einfach zu bedienen und selbsterklärend. Eine große Empfehlung 👌

### 5/5 — Great 🌟

*2022-01-26*

Such a handy app for working out shift hours before doing timesheets etc

### 4/5 — Cool Gadget

*2019-08-29*

UI might be a bit more self explanatory for my taste

### 5/5 — genau sowas hatte ich gesucht

*2019-08-18*

Eine tolle App, ich nutze sie um die genaue Zeit für h und min in meinen Brotbackautomaten einzugeben damit der Countdown zu einem fixen Zeitpunkt auf die Minute genau ist, so dass ich Morgens frisches Brot habe. Ist natürlich auch ohne App schnell zu berechnen aber es erleichtert die Programmierung am Automaten doch sehr.

### 5/5 — Brilliant

*2019-08-09*

I have a very flexible work schedules but am not allowed overtime. I’ve been having a “hard time” clocking out at precisely the right time. My supervisor mentioned it to me several times much to my embarrassment. I spent a good hour looking for solutions (I refuse to do my own calculations when I know there’s a better way) until I found this. Now no matter when I clock in or how long I take for lunch I’ll know precisely when to clock out to get my 8.
