About
Fox Tail is a private calendar of your intimate life – for one person or for two. Everything is stored on your device, without an account and without ads.
CALENDAR
Mark an entry in one tap or describe it in detail: protection, place, mood, partner, time and notes. Save frequent entries as templates and keep solo entries apart from shared ones. A built-in timer measures the duration and shows it on the Lock Screen as a Live Activity.
QUICK ENTRY
Add an entry or start the timer with Siri, Shortcuts, the Action button or Control Center – without opening the app.
STATISTICS
Month, year and all-time summaries: streaks, averages, best days and hours, heatmaps and a Year in Review poster you can share. "Compared with others" gently puts your numbers next to large population studies – no judgment.
MEDALS
Achievements are illustrated medals – keepsakes of your story, not a race for numbers.
CYCLE
A full period tracker with a new home screen: cycle ring, week at a glance, quick marks, phases, forecast, fertile window, symptoms and reminders – with import from the Health app and a link between your cycle and intimacy.
DESIRE AND HEALTH
Log your desire level during the day and see how fast it returns after intimacy. Keep STI checkups and results in one place, with retest reminders and a heads-up after a new partner.
SERVICES
Personal journal of moods and events, firsts, partner profiles, supplies with expiry dates, and letters to the future that unseal on a date or an event.
GAMES FOR TWO
Wish jar, Duet blind notes, Secret Scenario, Magic Ball, 3D dice, Truth or Dare and Would You Rather with Matches and Guess me modes.
FOR COUPLES
Link with your partner through iCloud: shared wish jar, joint notes and pokes. Every kind of shared data has its own switch – you decide what your partner sees.
PRIVACY FIRST
Face ID / Touch ID lock and instant lock when you put the phone face down. A Focus filter hides private content, and neutral app icons keep the app discreet on your Home Screen. A secret media container that bypasses your photo library, encrypted backups in one file, CSV and PDF export. No account, no analytics, no advertising. Your data is never held hostage: viewing, editing, export and backup are always free.
MAKE IT YOURS
Picture themes Clay, Night, Neon and Glass for medals, the calendar and illustrations, light or dark mode, 14 accent colors, background patterns and over 60 app icons. Plus Home Screen widgets, an Apple Watch app and 12 languages.
FOX TAIL PLUS
One-time purchase, no subscriptions. The free version adds 2 new entries per calendar month (solo entries don't count); the calendar, core statistics, cycle, services, backups and most games are free forever. Plus removes the limit, adds desire recovery insights and other extras, and unlocks automatically for your linked partner too.
