Cooldown: Phone Temperature

Cooldown is a phone temperature monitor for Android. Check your phone temperature and battery temperature at a glance, get an alert when your phone is overheating, and follow practical tips to cool down your phone.

Cooldown uses the temperature readings that Android itself provides. It shows what is heating up your phone, such as charging, screen brightness, heavy apps or a weak network, and what you can do to keep it cool.

WHAT COOLDOWN DOES NOT DO
Cooldown is not a phone cooler or CPU cooler app that claims to cool your phone instantly. It does not force-stop apps, lock CPU or GPU speeds, require root or read private system files. Instead, it shows what is really heating your phone and how to cool it down safely. Available sensor data varies by device and Android version.

Phone temperature monitoring and overheating alerts are always free.
