## What is Tidelle?

Your cycle, only on your phone.

A period and cycle tracker with no account, no login, no cloud and no ads. Everything you log stays on your phone unless you choose a backup folder or switch on phone backup.

KNOW WHAT'S COMING
• Your next period and fertile window, estimated from your own cycles, with an honest range that widens when your cycles vary
• A heads-up the day before a symptom usually starts, learned from your past cycles (Pro)
• A ring on the Today screen that shows where you are in your cycle at a glance

LOG IN SECONDS
• Period, flow, 33 symptoms, 24 moods, energy, sleep and libido, one tap each, plus notes
• Body signs if you want them: temperature, cervical mucus, ovulation and pregnancy tests
• Weight, breast self-exam and your own custom symptoms

REMINDERS THAT FIT YOUR LIFE
• Before your period, and when your estimated fertile window begins
• A gentle daily nudge to log
• The pill: every day, 21+7, 24+4 or your own pack
• The ring, the patch or the injection
• A monthly breast self-exam
• Each at a time you choose, with a reminder sound you pick

FOR EVERY STAGE
• Perimenopause: no "late" alarms when cycles start to change, plus hot flash and night sweat trends (Pro)
• After giving birth: cycles counted from your baby's birth date
• Pregnant? Predictions pause, and our app Plippo Baby takes it from there

TAKE IT TO YOUR DOCTOR
• A clear PDF report: cycle and period length, variation, recent cycles and top symptoms
• Gentle notes on patterns doctors often ask about, such as very short or very long cycles

PRIVATE BY DESIGN
• No account, no email, no password
• Your data stays on your phone unless you choose a backup folder or switch on phone backup
• App lock with Face ID, Touch ID or your passcode; reminders and the widgets stay neutral while it's on
• A discreet icon if you want one, and delete all your data any time
• Your data is yours: export a backup or a CSV any time, or turn on automatic backups to a folder you choose
• Switching apps? Import your history from Clue, Flo or any CSV

FREE, WITH AN OPTIONAL ONE-TIME PRO
Everything above is free unless marked Pro: predictions, the fertile window and its reminder, every reminder, the doctor report, backups and CSV, and the Crystal theme with Dusk, Bloom or your own photo.
Pro is a one-time purchase, never a subscription. It adds symptom and mood patterns and the heads-up, temperature and weight charts, perimenopause trends, more themes like Glow and Lumen, more Crystal backgrounds, Follow my cycle colors and eight more sleep sounds.

Also: Home Screen and Lock Screen widgets, sleep sounds with a timer, light and dark mode and larger text support.

Not medical advice · not a contraceptive method · predictions are estimates
If something worries you, talk to a doctor.
