HOW IT WORKS
• Enter the date her last period started — that's the whole setup
• Each day, answer one question with one tap
• TideBook blends the textbook curve with your couple's own pattern, and the forecast gets sharper every week
WHAT YOU GET
• Today's outlook at a glance, with the current phase explained in plain words
• A fourteen-day forecast strip
• The full cycle view: where she is in the month, and the best days ahead
• A next-period estimate that adapts to her actual cycle length
PRIVATE BY DESIGN
Everything stays on your phone. No account, no cloud, no analytics, no data collection of any kind.
TideBook is not a medical device and not a contraceptive method. Predictions are estimates, and cycles vary widely.
