Your cycle.
Your data.
Your phone.
A beautiful period tracking app that installs directly on your home screen — no app store, no subscription, no one else's servers. Just you and your data.
Everything you need
Built for real life,
not an app store
Six-step daily logging that feels like a native app. No fluff, no dark patterns, no upsells.
Log your period status, flow, pain, mood, energy, symptoms, medication, temperature, and sleep — one screen at a time. Required fields are validated so you never submit an incomplete entry.
See your last period, next expected period, current cycle phase, and your personalised average cycle length — all calculated from your own logged history, on your device.
Every entry saves directly to your own private Google Sheet. One-time setup, guided step by step inside the app. Your data, your spreadsheet, no middleman.
Install it to your iPhone or Android home screen in 30 seconds. Opens full-screen like a native app, works offline, and has its own icon.
Follows your system preference automatically, or toggle with one tap. Looks great at any hour.
No account, no login, no ads, no trackers. Your data goes straight to your own Google account. Nothing touches anyone else's server.

Your health data
belongs to you
Period tracking apps have a long history of selling user health data. Cycle Tracker was built so that can't happen — because your data never touches anyone else's server.

Questions
Everything you
might wonder
Not at all. You just need to paste your licence key to unlock the app, and follow the in-app guide to connect your Google Sheet. That's it.
Date, cycle day, period status, flow intensity and colour, pain level (0–10 slider), pain locations, mood, energy level, 11 physical symptoms, medication taken, basal body temperature, sleep hours, and free notes — all optional except the required fields.
Yes. Once added to your home screen it opens full-screen with no browser bar, has its own app icon, and works offline. The install button is built right into the app — tap it and follow the 30-second guide.
Yes. The app detects your device and shows the right install instructions automatically — Safari Share menu for iPhone, Chrome install prompt for Android.
After unlocking, the app walks you through a one-time setup: paste the Apps Script into Google Scripts, deploy it, and paste the URL into the app's ⚙️ Settings. A green dot confirms it's connected. Takes about 5 minutes and is guided step-by-step inside the app.
