About this app

🔥 THERMAL MONITOR

Lightweight & Unobtrusive Phone Temperature Monitor and Thermal Guardian
Is your phone heating up during heavy use or gaming?
Is thermal throttling affecting your experience or results?

Thermal Monitor helps you track your phone temperature and CPU throttling state in real-time and act before overheating impacts your results or device health.

With Thermal Monitor, you'll have a thermal guardian watching over your phone, alerting you when battery or CPU temperature spikes or thermal throttling occurs. Designed for minimal impact and optimized for gaming, this temperature monitor app features a clean, distraction-free interface with a customizable status bar icon and floating widget that stays out of your way while keeping you informed.

Key Features:
🔹 Track phone temperature and thermal throttling in real-time
🔹 Sleek, unobtrusive and customizable floating widget
🔹 Status bar icon, temperature notifications and spoken updates
🔹 No ads, no internet requirement, no unnecessary permissions
🔹 Tiny app size, ultra-low RAM & CPU usage for zero impact on performance

Your phone automatically manages overheating by throttling performance to prevent device damage. Thermal Monitor helps you to stay informed so you can take action — whether by adjusting settings, closing background apps or using an external GPU and CPU cooler.

Premium Features:
⭐ Extended floating widget customizations – choose background and foreground colors, opacity and what icons and data to show
⭐ Customize the notification icon – indicate throttling, temperature or both
⭐ Select temperature sensor – battery temperature, CPU temperature, GPU temperature or other ambient temperature sensor (sensor availability is device dependent)
⭐ Multiple temperature monitors in floating widget, e.g. battery + GPU + CPU temperature (not available in all devices)
⭐ Enhanced precision – choose update interval and extra decimal for more accurate readings
⭐ Temperature and throttling warnings – get notified when your phone temperature or performance throttling reaches critical levels

Please note that you should always be able to rely on the throttling info provided by the operating system and shown in the app. Some devices allow for direct GPU and CPU temperature monitoring, but unfortunately not all. All devices will however report the battery temperature and thermal throttling state, which is still a great indicator for whether your device is overheating or cooling down (can be verified with a CPU load generator). All temperature monitor apps read the same phone temperature data made available by the operating system. This is why we focus on giving you the best user interface, customization options and means to optimize for either accuracy or low impact on performance and battery usage.


❄ Stay cool & game on!

I have a Samsung galaxy S22 Ultra 5G. When I've installed this app and had the phone sitting there doing virtually nothing (making sure I've killed non essential apps to the running of the OS in completely., At that moment the phone is cool physically. It gets so hot I cannot touch it for more than 3 secs. Switches itself off sometimes. This model phone has a BIG problem with heat/heat dissipation. Therefore I've bought S26 & will keep U informed. I hope the App is not a contributing factor.

Hi! Sorry to hear, but this device really seems broken.. 😢 We have spent a lot of energy creating an app that has a minimal cpu, memory and disk footprint. It would be extremely surprising if the Thermal Monitor caused any of this. Too hot to touch is a really bad sign. Spontaneous restarts is likely a result of the heat. What throttling level?

1.99 for lifetime is insanely worth it, app works as intended the temps are accurate and everything is simple to use. I've just one suggestion. maybe add a floating setting too so that instead of the monitor being confined to the screen edges we can move it anywhere. ✌️

Thanks for your great feedback and suggestion! Will definitely see how we can develop an "undocked" mode there as well. 🙂

this app tells the mobile temperature exactly 💯 and also shows a throttle meter for free. A great app uses very little memory for showing temperature. great app if your mobile does not show temperature in build.
