DeviceBeat vs Thermal State

DeviceBeat brings your device activity into one clear dashboard, with native layouts for iPhone and iPad. MONITOR YOUR DEVICE • CPU activity and processor information • Memory usage and available storage • Network traffic, connection details and optional latency checks • Battery level, charging state, thermal state and Low Power Mode • Local history, trends and configurable alerts KEEP KEY READINGS CLOSE Add small, medium or large Home Screen widgets. Customize a compact monitoring panel and use the floating window to follow device activity while working in another app. PRIVATE BY DESIGN No account, advertising or analytics SDKs. Measurements and history stay on your device. The optional network latency probe is off by default; when enabled, it opens a TCP connection to captive.apple.com without uploading measurements. Available readings depend on the device and iOS permissions. Detailed process lists, battery health and cycle count, fan speeds and hardware temperature sensors are not exposed on iOS. Unavailable readings are explicitly marked. Widget refresh timing is controlled by iOS.

Your iPhone manages heat quietly. It slows the processor, dims the screen, pauses background work, and never mentions it. Thermal State mentions it. The app reads the thermal state iOS itself uses to make those decisions — Nominal, Fair, Serious, Critical — and puts it on one screen, in one color, with a plain-language explanation of what the system is doing and what you are likely to notice. ON THE SCREEN - The current thermal state, in full color - What that state means and what it affects - Thermal pressure and memory pressure - Uptime - Battery level and charging status - Low Power Mode - Processor, CPU core count, and active cores - Physical RAM - Radio access type - Storage used and total capacity - System version, device model, and locale - The time the current state began - An option to keep the screen awake while the app is open COLOR SCHEMES The four state colors are a default, not a requirement. Swap them for another palette — including one that trades green and yellow for white and cyan, for anyone who doesn't read green as calm. WIDGETS Home Screen: a Medium widget showing the state, its color, battery level, Low Power Mode, and uptime. Lock Screen: inline and circular widgets, so the state is there before you unlock. WHAT IT DOES NOT DO It does not report degrees. iOS does not make a temperature reading available to apps. What it does make available is the four-state assessment the system acts on — which is the reading that actually predicts what your phone will do next. It does not cool your phone down. No app can. It tells you when your phone is cooling itself, and how hard it is working at it. PRIVACY No account. No sign-in.
