Periodicity is a new reminder app for the iPhone. With Periodicity you can easily configure any periodical event or task you want to be reminded of, whether it is an anniversary, a weekly appointment, your workout every third day or a daily meditation session.

What's even better, you can accept, dismiss or postpone every single reminder and Periodicity keeps track. So you still know at the and of the day if you've taken the memory pills in the morning. 

 

Periodicity for iPhone is available on the App Store for 99¢.
