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!

It does what's on the tin, but since it was bundled with an arcade app, I figured it was going to auto launch when I launched the game like how every other game monitor style application works. I think I would have liked this app a lot more if it auto-launched when I opened games and then closed itself when I left the game Instead of having to either have it always on or turn it on before I play a game and then turn it back off again.

Exactly this is a feature/setting we have planned to add in a future release. Thanks for reminding us, and pointing out that more users are interested in this! 🙂 (Doesn't change anything, but a quick way to start the Thermal Monitor is to tap the temperature icon in the game launcher)

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.

Hi! Thanks for your review and pointing this out. Will investigate and see if this is possible to do.

I love this app! it's great to always be able to see your phone or tablet's temperature, it's surprising which apps or environments make it run hot. The battery current monitor doesn't work on my phone for some reason, which is a shame, but the rest is flawless. I can't find a way to contact the developer for tech support, so I hope they reply to this review.

Hi! You should see our email (rollerbush@gmail.com) somewhere but via review is also fine. Just a bit less detailed responses ☺️. Devices will still be the determining factor when it comes to what data can be read/shown, but we should be able to at least not show a non-reliable battery current. Sorry to hear that it's not supported in your device.

What’s new

• New widget touch options, including quick one-tap navigation back to our game launcher (The Arcade)
• Available memory indicator for the floating widget (premium feature)
