Radia home screen showing a one-day streak, two minutes logged today, a weekly summary card with four sessions and Face as the top body area, and a Last Session card

Track every minute

A distraction-free timer, eight body-area tags, optional device and notes. Just a clean record of what you did and when.

Your streak, visible

Daily sessions build a streak. Weekly summary shows minutes, sessions, and your top area at a glance.

Real session journal

Rating, notes, before and after photos on every session. Filter history by body area. Export to CSV when you want your data out.

Device-agnostic

Works with any panel, mask, or wrap. Not a hardware companion, not a phone-screen gimmick. Add device profiles with irradiance and get automatic dose totals in joules per cm².

Your data, your device

No account needed. Offline-first. Syncs across your Apple devices via iCloud — nothing sent to my servers, because there are no servers of mine. No tracking, no analytics.

One price. Forever.
