Sola: Period & Cycle Tracker

The period tracker that never makes you anxious.

No calendar to fill. No "chance of pregnancy" meter. No account, no server. What you log stays on your phone, and your notifications never say what they are about.

Stop paying and Sola turns read-only, never locked. You can still read and export everything you logged, always. Your data was never the product.

ONE SENTENCE, ONE STRIP
Open Sola and a single sentence tells you where you are today. One strip lets you move through your cycle: press it, drag, and travel in time. Log a period, a symptom, a mood, a temperature, or a test with one tap. There is no save button, because it saves itself.

TRACK A CYCLE, TRY TO CONCEIVE, OR FOLLOW A PREGNANCY
Sola predicts your next period and your fertile window from your own history, not a population average. When it is not certain, it says so in plain words instead of pretending.

LATE? IT STATES THE FACT AND STAYS QUIET
No cause speculation. No "take a test" nudge. No red alert. A late day is information, and Sola treats it that way. Trends show you patterns across cycles, never a score out of ten.

PRIVATE BY HOW IT IS BUILT, NOT BY PROMISE
Everything you log is stored on your phone. There is no account to create and no server of ours to sync to, so there is no copy of your cycle data for anyone to take. Notifications stay deliberately vague, so a glance at your lock screen tells no one anything.

FAIR ABOUT MONEY
Sola is a paid app with a free trial. Every price is shown by the App Store in your own currency. Cancel and your logs are never held hostage: the app turns read-only and your export keeps working forever.

BUILT FOR EVERYONE
Full VoiceOver, Dynamic Type, and Reduce Motion support. The strip, the sentences, and every value you log are read aloud, and the layout holds at the largest text sizes.
