Radia
A quiet log for red light therapy. It's device-agnostic, it's honest about what red light does and doesn't do, and it stays out of your way while you actually sit in front of the panel. Pay once, no subscriptions.
Why this app exists
Red light therapy apps generally fall into two camps: phone-screen "therapy" apps (physics says no — a phone screen cannot emit the wavelengths or power that real RLT panels do), or hardware-companion apps locked to one brand's devices (great if you own that exact brand, useless otherwise).
Radia is built for the rest of the market: people who already own a real red light device — a Joovv panel, a Mito Red mask, a PlatinumLED wrap, a Bon Charge wand, or anything else — and want a clean way to track what they're actually doing with it. A session timer, body-area tags, dose calculation if they want it, and a record they'll actually read next month.
Features worth calling out
Distraction-free session timer free
Start, pause, end. No notifications, no upsells, no ads. Just a quiet timer counting up while you sit in front of the light.
Eight body-area tags free
Face, Chest, Back, Arms, Legs, Joints, Full Body, Other. Tag every session so your history is actually meaningful later.
Streak + weekly summary free
A gentle pressure to stay consistent. Minutes, sessions, top area — all at a glance on the Today screen.
Session history with filters free
Every saved session, grouped by week, filterable by body area. Tap through to see ratings, notes, and photos.
Before and after photos pro
Attach a before and an after shot to every session. Scroll back weeks later to see whether anything actually changed.
Multiple device profiles pro
Track a panel, a mask, and a wrap separately. Set each one's irradiance and Radia computes total dose in J/cm² automatically.
Home Screen widget pro
Small and medium widgets showing your week's minutes, sessions, and top area. No taps needed.
CSV export pro
Every session, every field, as a spreadsheet. For the biohackers who want their own dashboards in Numbers or Notion.

Optional: write each session to Apple Health as a mindful minute, alongside meditation and breathwork.
