The application you have before you is but a small attempt at working with time. Since it's a precious commodity all we can do is spend it wisely. That's why I've decided to spend a bit of my time and create Decima (named after Roman Parca, the female personification of destiny) so that you don't have to ;) So what you can do with Decima? In the current version 1.1 (JosΓ©phine) you can: β€’ create multiple timers β€’ set multiple alerts per timer to track time expenditure β€’ use it on both: your iPhone and Apple Watch (iPhone application is necessary) β€’ start/stop timers on demand from your iPhone/iPad or Apple Watch β€’ organize your time in sets β€’ see total/partial time spent for a particular timer β€’ automatically synchronise data between your iPhone and your Apple Watch (timer started on your phone can be paused on your Apple Watch and vice-versa) Have fun.

About

Divisors

Read full description

This app can tell you if a number between 0 and 20000 is prime or not. It can also determine all divisors of any number less than 10000000. Fancy a game? Then you can try the quiz and collect points. Siri Shortcuts are also supported: You can also use your shortcuts to check whether your number is a prime number or not. Another shortcut can give you all the prime numbers from 0 to your entered number in a list. A shortcut can be used to determine all divisors of any number less than 100000, so the shortcut doesn't take too long.
