Vibe Days is a private period and perimenopause tracker. Everything you log stays on your phone: there's no account to create, no server, no ads and no tracking, and it works offline.

Track your period, symptoms and mood
• Log a period in one tap: Period started when it starts, Period ended when it ends. Forgot? Pick an earlier day, or let the app end it for you.
• Note how each day went: flow, mood, symptoms from cramps to brain fog, energy, discharge and intimacy, with a tap on an icon. Add your weight and waist now and then, and a short note for anything else.
• Fold, hide or reorder the sections, so the daily log shows what you track, in your order.

Perimenopause and irregular cycles
• Note how long and how well you slept, and how many hot flashes and night sweats you had.
• Turn on My cycles are irregular, for example in perimenopause or after stopping the pill: cycles of up to 90 days count, and predictions show a wider range.
• The app won't tell whether you're in perimenopause. It records what you log, so you can see how things change.

Honest predictions
• The calendar shows your logged periods, your next predicted periods and an estimated fertile window, for the next three months.
• Predictions are a range of days, not a single date. When your period is late or your cycles look unusual, the app says so.

Charts
• Your average cycle and period length, and how much your cycles vary.
• Each cycle as a bar with its period, your weight and waist over the months, the days of your cycle when each symptom or mood tends to come, hot flashes and night sweats week by week, and your sleep and energy day by day.
• Plain facts, no targets and no judgement.

Reminders that follow your real cycle
• A reminder for a day after your period actually starts or ends, like "on day 10 after my period starts". It waits until you log it, so it follows your cycle, not a guess.
• A heads-up before your predicted period, a daily check-in, and a nudge when your period seems late.
• By default the lock screen only says "Vibe Days reminder".

Medications and supplements
• Keep your own list, like HRT gel, magnesium or iron, and tick off what you took on the Today screen.
• Reminders every day, on chosen weekdays, monthly, or on and off like 21 days on and 7 off. Tap Taken or Snooze right on the notification.
• The app doesn't tell you what to take.

A summary for your doctor
• The last 1, 3 or 6 months on one page, as a PDF to show or print at an appointment: cycles, symptoms and moods, hot flashes, night sweats, sleep and the medications you took.
• Need every day? Export a spreadsheet for Excel, Google Sheets or Numbers.

Your data stays yours
• Everything is stored only on your phone. No account, no ads, no analytics.
• Move to a new phone with one backup file, encrypted with a passphrase only you know. You decide where the file goes.
• Delete everything the app has stored with one button in Settings.

In English, Spanish and French. The app starts in your phone's language, and you can change it in Settings.

Not birth control, not medical advice
Predictions are estimates based on the periods you log, and cycles vary. Don't use them to prevent pregnancy. The app doesn't give medical advice: if something about your cycle worries you, talk to a doctor.
