RedDose is a session timer and routine log for red light therapy — time your sessions, log which body area you targeted, and watch your streak build over time. ■ Built for however you do red light Set up a device profile for your panel, mask, wand, or belt — each with its own default session length. Switch between devices in one tap without re-entering settings every time. ■ Mid-session flip reminder Set a flip point and RedDose alerts you halfway through — turn to cover your front and back, or switch body areas, without watching the clock yourself. ■ Log by body area, see your week Every session is logged to the body area you targeted (face, back, shoulder, knee, and more). A weekly view shows total minutes and session count per area, plus a streak counter that keeps your routine visible. ■ Progress photos, kept private Add a before/after photo to compare over time, with an angle guide to help you frame the same shot each time. Every photo stays on your phone — RedDose never uploads anything, anywhere. ■ What you get • Session timer with a configurable mid-session flip reminder • Device profiles (panel / mask / wand / belt) with saved default durations • Per-body-area session log • Weekly stats: total minutes, session count, per-area breakdown • Streak tracking • On-device progress photo comparison — nothing leaves your phone • Dark and light themes • Works on iPhone and iPad • 8 languages ■ Private by design No account, no upload — everything, including your photos, stays on your phone. Remove ads and unlock unlimited device profiles and photo comparison with a single one-time purchase, forever. Note: RedDose is a session timer and log for your own red light routine. It does not diagnose, treat, cure, or claim to improve any medical or skin condition, and is not a substitute for professional medical advice — it simply helps you track the routine you already do. Always follow your device manufacturer's instructions and consult a professional for any health concerns.

Verdict
The clearest difference is ads: RedGrid at none against RedDose's shown. RedDose's advantage is update cadence (weekly vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
