About this app
cycle.log is not "yet another period tracker." Unlike other menstrual cycle trackers, cycle.log makes is extremely simple to log your cycles and see when your next period is going to start. Not only is it easy to log your cycles, but cycle.log will also send you a friendly reminder before your next period so you can be prepared. The more you use cycle.log the smarter it becomes. Every time you log a cycle the app automatically adjusts your average cycle length and uses that to estimate your next period. It also calculates the standard deviation of your cycle length which tells you how different your cycles are from one another. Please give cycle.log a try and be sure to tell your friends!
