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!

Best Tracker I’ve found
I’ve been tracking my period on the same website for almost 12 years and unfortunately it is shutting down. I’ve downloaded a lot of apps trying to find something that was similar to the website I was using and this has been the closest!
I uploaded a few months of previous data and the estimated cycle durations and standard deviation changed as it should unlike many of the other apps I’ve tried. I love that all the way information I need is easy to see all on one page, such as next predicted period, next predicted ovulation, cycle length, standard deviation, last cycle date, and what cycle day I’m on. I also like being able to see how long each cycle is which is easy to view at a glance in the log.
Improvements that would make me love this app even more would be: Next to the dates, add in parentheses how many days until or ago something was. For example Next Ovulation Friday, September 23 (12 days away) or Last Period Sunday, September 4 (7 days ago). I didn’t realize how helpful this was in my old website until I didn’t have it anymore. I’d also like to be able to make simple notes. I track ovulation so being able to note in the log what date it happened is helpful.
I love how simple and basic this app is. It doesn’t ask me to track one million symptoms, no ads, no unnecessary fluff. And one of my favorite things is that it doesn’t ask me how many days my bleeding lasts! I never keep track of all that extra stuff. I only want to know when each cycle starts, estimated ovulation, what cycle day I’m on, and on average how long are my cycles.
