sCycle is a period tracker with a companion. Pick Mo the otter or Juno the fox, give them a name, and they keep you company through the month. Every day starts with where you are: your cycle day, your phase, and when your next period is due. Your companion adds a line that fits the day. Mo is warm and a little silly. Juno is practical and helps you plan. CHECK IN WITH A FEW TAPS Mood, flow, and how your body feels: cramps, tiredness, bloating, headache, tender breasts. Tap what applies and skip the rest. If your period started, say so and the calendar moves with you. YOUR WHOLE CYCLE ON ONE SCREEN The calendar shows your periods, the next one predicted, and your fertile window. Tap any day to add, move or remove a period start. A COMPANION THAT REMEMBERS Had cramps around this time last cycle? Your companion will mention it and suggest something that helps. When a new cycle starts, you get a short summary of the last one. WHAT EACH PHASE MEANS Tap your phase for a plain explanation of what's going on in your body and what tends to help. PRIVATE BY DEFAULT Your cycle stays on your phone. You don't need an account. There are no ads, and your data is never sold. If you want your log on a second device, sign in and turn on Sapplify Sync. It's free and stays off until you switch it on. You can export everything to CSV or delete it all, any time. ALSO - A daily check-in reminder at the time you pick - Light and dark mode - 23 languages FREE, WITH ONE OPTIONAL PURCHASE Tracking is free, with no subscription. Pro is a one-time purchase that unlocks every companion, so you can switch between Mo and Juno whenever you like. sCycle predicts from your own history. It is not medical advice and not a method of contraception.
