CoolMonitor vs Phoebe

CoolMonitor helps you grasp the status of your device at a glance. CPU usage, screen refresh rate, network activity, storage and heat status are all concentrated in a clear panel. After enabling the charging detection, the charging power can be continuously observed. The results are only saved on the device itself, making it convenient to compare different charging processes. Key data can also be viewed at any time through native floating display, real-time activities, dynamic island and home screen widgets. Core functions View CPU usage, screen refresh rate, network activity, storage and heat status • Observe charging power • Review the charging history saved on this device • Continuously view key indicators through native system display • Rich and diverse custom display methods. And switch between Simplified Chinese, English and Traditional Chinese at any time.
