Flory: Period & Cycle Tracker

Flory 4.0 is a rebuild. No account, no login — your records stay on your phone. Forecasts now carry ranges and confidence. Plus is one-time, not a subscription.

"Why do I feel like this today?" — the answer is usually somewhere in your cycle.

Flory isn't just a place to log your period. It's built to tell you which phase your body is in today, what tends to happen next, and how sure it actually is.

TODAY'S FORECAST Open the app and the ring shows your phase, the day of your cycle, and how long until your next period. It shifts a little every day.

HONEST PREDICTIONS, WITH RANGES Flory won't tell you "your period starts on the 14th." It says "around the 12th–16th, medium confidence." When there isn't enough data yet, it says so: "log two more cycles and this gets sharper." No invented precision.

EVERY KIND OF LOG, FREE Period, mood, symptoms, sleep, skin, weight, pain, basal body temperature, LH tests — no logging field is behind a paywall, and there's no cap on entries. Today's log takes about three seconds.

YOUR OWN PATTERNS As entries build up, Flory surfaces patterns that are yours: headaches clustering before your period, mood dipping in a particular window. Drawn from your data, not a population average.

TRYING TO CONCEIVE Turn on TTC mode to log basal body temperature and LH strips, and Flory narrows your fertile window using what you actually recorded. Toggle it on or off whenever you like.

YOUR DATA NEVER LEAVES THIS PHONE There is no account. No login. Your records never reach our servers — we didn't build a path for them to travel. Backups are written as encrypted files locked with a password you choose, and they stay on your phone unless you share them. Moving to a new phone happens over a QR code, encrypted the whole way.

APP LOCK Protect Flory with Face ID or a 6-digit passcode. Free.

SEVEN STYLES Cream Veil, Moonlight, Sage, Peach Fizz, Ember, Velvet, Ink Dusk. Pick whichever fits today.
