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 now use this on both of my phones. it actually helped me know why my S24 ultra was overheating I just replicated what I was doing on it with my 2nd phone and BAM problem fixed. Plus I can see my CPU temp at all times so I know when to shut down certain apps and whatnot. love it. everyone should use this! ALSO the OSD is super small and non intrusive much appreciated on that one.

Life a Little Differently

Extremely useful and simple. I highly recommend this app! I use it to minimize damage to my phone and lengthen its life. Basically, this app will save you money! Just keep your phone between 32°-95°F (0°-35°C), and your battery and hardware won't be damaged by the internal temperature. For the developer(s): The only suggestion I can think of is to make the widget not appear in screenshots/screen recordings. Thank you so much for making such a useful app!

Thanks for your great review and feedback! Will investigate the screenshot issue, but assume the only thing we can probably do is to make showing/hiding the widget easier.. hmm 🤔 (can btw currently be toggled from the notification action and the quick action tile)

Unfortunately, this app doesn't display the battery information on the lock screen after locking the phone. Even with "Lock Screen Notifications" set to "Show Content" in the device notification settings for the app. I would like to be able to see the battery information from my lock screen so I can glance at it, without having to unlock the phone. Unless I'm missing a setting somewhere. Everything else is great.
