About

Seen Together

Features
Read full description

Seen Together is a gentle, private space for hard days. Track how you feel, notice the patterns over time, and walk into your next doctor's appointment prepared — with a clear record instead of trying to remember everything on the spot. Everything is optional, and everything stays on your device. WHAT YOU CAN DO • Log a moment in under a minute — pain intensity, location, bleeding, symptoms, medication, or a quick note. Only fill in what you have the energy for. • See the pattern — a calendar and history view with period, fertile, and cycle predictions, so the bigger picture comes into focus. • Prepare a doctor report — turn your logs into a clear summary you can share at your next appointment. • Gentle reminders — small, optional nudges to check in, on your terms. PRIVATE BY DESIGN • Your health records are stored only on your device, in an encrypted database. • No account required, ever. • No ads, no advertising trackers, and your data is never sold. • A record leaves your device only when you choose to share a report. MADE WITH CARE Made by one person, with a lot of care — no investors, no growth-at-all-costs. If it helps you, you can leave an optional tip to support development, but the app is completely free and nothing is ever locked behind a purchase. Seen Together helps you prepare for appointments. It does not diagnose, predict disease, or recommend treatment. Always consult a healthcare professional about your symptoms.
