### 4/5 — Calendar doesn’t work!

*2020-07-25*

In dark mode, please fix. Otherwise this is my favorite time calculator. I’ve been using for many years.

### 1/5 — Баг интерфейса

*2020-02-19*

Iphone X. При нажатии на кнопарик вызова дат появляется пустой экран.

### 2/5 — Não transforma horas em dias.

*2018-06-28*

Poderia apresentar o resultado em dias.
Ex.: 9h / 8hs = 1d 1h ao invés de 1,125s

### 5/5 — Topissime

*2016-12-06*

Je l'utilise pour rédiger mes factures depuis... Ouh... Longtemps!!! Il faut juste un cerveau sans trous pour saisir les manips!!

### 5/5 — Очень полезное приложение

*2016-03-10*

Помогает на работе, очень удобное

### 5/5 — Super programmiert, besser als alles andere.

*2015-12-17*

alle anderen Zeitrechner erlauben entweder nur das Datum oder die Uhrzeit zu berechnen. Habe da Geld zum Fenster rausgeworfen bei den anderen Apps.
nur diese App kann Tage und Stunden zu einem bestimmten Datum mit Uhrzeit hinzu addieren beziehungsweise berechnen. 
somit kann ich zum Beispiel die Reichweite einer Gasflasche die in einem Ofen drei Tage 14 Stunden heizt genau berechnen, und weiß wann der Ofen ausgehen wird.
macht was es soll super weiter so.

### 4/5 — Good app for calculating film development time

*2015-09-14*

There’s one bug though: you can’t make a calculation with a number starting with a decimal.

For example, I need to purposely underdevelop a roll of film by 40%, so (N x .6) where N= the base time I’d use to properly develop a roll, in this case 7 minutes.  So in the app I want to type "7m x .6” but it won’t let me enter the “.” .  A workaround is to type “7mx6⬅️.6” where ⬅️ is the backspace.  It then properly shows the formula at the top like so:

7m x .6=

Fix that and I’ll upgrade my rating to 5 stars :)

### 4/5 — Almost the tool

*2015-04-26*

Best application I found after purchasing and trying so many. I have these suggestions:

1) Application doesn't offer any help to understand functions.

2) Application doesn't give an option to write concerns to developer.

3) Sometimes calculations are way off. 

4) No way to post an event in the calendar that will reoccur every x days, x hours, x minutes, x seconds as calculated by the app.

Still it is the best and I hope the developer reads my suggestions.

### 5/5 — Works great

*2014-08-19*

Great for FAR117 legalities

### 1/5 — Ne sert a rien

*2014-04-10*

Ne permet pas d'additionner ou de soustraire les heures comme annoncé
