Timely: Time Calculator app for iPhone and iPad

Timely allows you to perform arithmetic operations between time spans and numbers! Addition, subtract, multiplication and division are all supported - no ads and completely free.

Timely displays time spans as Hour:Minutes:Seconds with support for decimals and order of operations (PEMDAS/BODMAS), it can also be used as a normal calculator.

Some examples of what you can do with Timely.

- What pace is required to complete a 12km race in 50 minutes?
50:00 ÷ 12 = 4:10 min/km

- Adding up timesheets for work.
07:30:00 + 01:00:00 + 02:25:00 = 10:55:00

Support for percentage and modulus are provided by the % key.

- Percentage calculation
10:00 + 5% = 10:30

- Modulus calculation
50:00:00 % 24:00:00 = 02:00:00
