Hand Warmer

Hand Warmer turns your phone into a small warmer. Pick a target between 30–55 °C on the round dial, start with one tap; once the target is reached the app adjusts the load itself and holds the temperature. WHAT FOR? • Keep your coffee warm — rest the cup on the phone and slow the cooling. • Stay warm in the cold — a warm surface for your hands while waiting, walking or commuting. • Warm your belly or back — put a thin cloth in between and don't use it while sleeping. • Emergencies — an extra heat source when stranded, during power cuts, camping or on the road. HOW IT WORKS • All CPU cores run, screen brightness rises and the screen stays awake. • Android reads the battery temperature sensor; iPhone estimates from the thermal state. • If the device approaches a critical temperature, it stops automatically for safety. FREE AND MEMBERSHIP • Free: 5 minutes of heating every 30 minutes. • Emergency: twice a week, 1 hour of non-stop heating — free. • Unlimited: monthly subscription, no limits. Heating increases battery drain; plugging in is recommended for long sessions.
