If you’ve been tracking data with your current app for some time, we understand there may be some hesitancy about changing period trackers. But Clue is set up so that—even from the start—you can get accurate cycle predictions.
It’s very easy to track past period data with our fast tracking feature. Just note down the dates of your last 3 periods (or even more is better) from your old app, and then follow the steps here to log them into Clue.
The Clue algorithm only needs 3 past cycles to calculate your core predictions with accuracy. Core predictions include your period dates, fertile window, and ovulation day. Please note that if you experience irregular cycles, then the algorithm may need more cycle data before becoming precise.
For cycle symptoms, like PMS and cramps, start tracking these experiences in Clue regularly and your predictions will soon follow. You can also manually add data from past cycles by scrolling back in your Clue Calendar View > Double-tapping the date you want to add data > Tracking your symptoms > Tapping ‘Save’.
