HeatCheck - Overheat Monitor

HeatCheck helps you understand why your iPhone gets hot during everyday activities like charging, gaming, camera use, navigation, or idle time. Start a focused heat session, choose what you are doing, and HeatCheck tracks public iOS thermal state signals together with battery level and charging status. You can review thermal trends over time, compare your worst scenarios, and get practical recommendations to reduce heat pressure. HeatCheck is useful when you want to answer questions like: • Why does my iPhone get hot while charging? • Does gaming increase thermal pressure? • Does navigation make my phone warmer? • Is the camera causing heat during long recording sessions? • What activity creates the worst heat conditions? Main features: • Start heat sessions for Charging, Gaming, Camera, Navigation, or Idle use • Monitor iOS thermal state over time • Track battery level and charging status during sessions • View thermal trend charts • Receive warnings when the device is getting hot • Review session history • Compare worst scenarios with heat scores • Get practical cooling recommendations HeatCheck Premium: • Unlimited heat monitoring sessions • Thermal trend charts with session history • Scenario ranking and heat score insights • Cooling recommendations for common overheating situations • Premium access to current and upcoming monitoring features Important note: HeatCheck uses public iOS APIs to monitor thermal state, battery level, and charging status. iOS does not provide third-party apps with exact CPU temperature, battery temperature, CPU frequency, GPU frequency, or precise throttling percentage. HeatCheck is designed to help you understand thermal pressure patterns and usage conditions, not to display exact internal hardware temperatures. HeatCheck is perfect for users who want a clear, simple, and privacy-friendly way to understand what makes their iPhone feel hot and how to reduce overheating risk.
