Tending: Cycle Tracker

A calm, private home for your menstrual cycle, water, and movement. Everything stays on your device — no account, no cloud, no tracking.

Tending is a calm, private home for the rhythms worth keeping an eye on: your menstrual cycle, your water, and your movement. No account, no cloud, no tracking — everything stays on your device.

MENSTRUAL CYCLE & MOON

• Log period start and end dates in seconds, and backlog past cycles too.
• Adaptive predictions learn from your history — the more you log, the sharper your next-period, ovulation, and fertile-window estimates become.
• A day-by-day phase ring shows exactly where you are in your cycle.
• Swipe to a moon view that tracks the lunar phase alongside your cycle.
• A full-year calendar map and a cycle-vs-moon chart reveal your patterns over time.
• An optional, gentle reminder before your next predicted period.

WATER

• Track every sip against a daily goal with a playful animated tumbler.
• One-tap quick-add buttons you can customize.
• Hydration streaks and pace-aware reminders that nudge you only when you fall behind.
• Optional, write-only sync to Apple Health.
• A Home Screen and Lock Screen widget with one-tap logging.

MOVEMENT

• A simple daily yes/no workout streak with a weekly goal.
• A 16-week heatmap so you can see your consistency at a glance.

PRIVACY FIRST

• All your data is stored only on your device. There is no Tending account and no server.
• No analytics, no ads, no third-party tracking.
• Lock the app behind Face ID, Touch ID, or your passcode.
• Your cycle data never leaves the app. The only optional sharing is water to Apple Health — off by default and write-only.

Tending is built to be quiet, warm, and yours.
