Every other app tracks her cycle for her. This one translates it for him. Her cycle affects everything: mood, energy, sleep, what she needs from you this week. Most women were never taught to read it. Almost no men were. PhaseMate is built to fix both. IF YOU'RE HER Log your period in seconds and see your whole rhythm on the world's first circular cycle calendar. Period, follicular, ovulation, luteal and late luteal, mapped where they actually sit. PhaseMate learns your personal pattern, so predictions get sharper the longer you use it. And when you're ready, hand the explaining over to the app. You shouldn't have to do it every month. IF YOU'RE HIM Add one date and PhaseMate works out where she is, what's coming, and what she needs. Not a lecture, a forecast. Which phase she's in today, when it flips, and what "I'm fine" means this week. Works on your own. Nothing is shared and she doesn't need to join unless you both want to. IF YOU'RE BOTH Link accounts and you're reading from the same chart. Fewer arguments that turn out to have had a calendar all along. WHAT YOU GET - The world's first circular cycle calendar - Predictions that learn your cycle, not a textbook average - Partner mode that teaches him your phases - Luteal and late luteal support for the hardest days to explain - Year view for planning travel and big moments around your best days THE MISSION Translate the female hormone cycle for men, so she never has to explain it again. Fewer arguments, more understanding, happier couples. It's time we started understanding each other. PhaseMate is a subscription app; pricing is shown at purchase.
