Please include your iOS version and a brief description of what happened. If the app crashed or misbehaved, a screenshot helps a lot.
Yes — Radia is device-agnostic. It works with any red light therapy panel, mask, wrap, or wand. Joovv, Mito Red, PlatinumLED, Bon Charge, Red Light Rising, and anything else. Radia is a session tracker, not a hardware companion — you bring the light, Radia keeps the record.
No. A phone screen cannot emit therapeutic red light — the wavelengths and power output are simply not in the range used by real RLT devices. Radia is purely a logging app. If you see other apps claiming otherwise, that's marketing, not physics.
Settings → Devices → + Add device. Name it, pick a kind (panel, mask, wrap, wand, handheld, other), and optionally add wavelengths, irradiance (mW/cm²), and distance. If you set irradiance, Radia will automatically calculate your total dose in joules per cm² for each session using that device.
Photos you attach to sessions are stored locally on your device and synced via iCloud to your other Apple devices (if iCloud Drive is enabled for Radia). They never leave the Apple ecosystem and are not uploaded to any server of mine. You can delete individual photos or full sessions at any time.
Pro unlocks CSV export. Settings → Data → Prepare CSV export. Each session becomes a row with body area, start time, duration, rating, notes, device, and dose. Open it in any spreadsheet or data app.
Yes. Sign in to iCloud on each device and Radia syncs your sessions, device profiles, and photos across them automatically. No account, no login — just Apple's built-in iCloud. Free for everyone, Pro or not.
Pro is a one-time $6.99 unlock (no subscriptions, ever) that adds:
Free always includes: session timer, all body-area tags, streak, weekly summary, history, filters, notifications, Apple Health integration, iCloud sync, and theme choice.
No. Radia is a logging tool. It does not diagnose, treat, or prescribe anything. If you have medical questions about red light therapy — suitability, dosing, contraindications — please consult a qualified professional.
Not yet. Radia is iOS-only for now. If demand is there, Android may follow — but the priority is making the iOS version great first.
In-app purchases are handled by Apple. If you'd like a refund, request one via reportaproblem.apple.com. I don't have the ability to issue refunds directly — only Apple does.
Always welcome. Send them to radia@charithp.com. I track them all and prioritize based on what users actually need.
