About this app

Running low on space right when you need it most? 📱

Phone Master brings cleanup, app management, and device information into one organized toolbox. See what is taking up room, choose what stays, and make everyday phone care feel simpler and more in your control. ✨

Your everyday device toolbox

🧹 Clean with a clear view
Scan cache files, installation packages, uninstall leftovers, and other cleanable items. Review categories and selected items first, then remove only what you no longer need.

🗂 Bring large files into view
Browse large files, images, videos, audio, documents, and app data by category. See what is using your storage and choose what you want to organize or delete.

📦 Keep your apps in order
View installed apps, storage size, and usage information. Select apps to uninstall and manage app notifications from one place.

📊 Know what is happening on your phone
Check memory, storage, battery level, and temperature. Use data usage tools and network speed tests to understand your current usage and connection status.

🔋 Get to know your battery
View battery health information and keep an eye on your phone's battery status.

🔒 Add an extra lock to selected apps
On supported devices, use a PIN, pattern, or fingerprint to lock selected apps and add access protection for private content. Availability varies by device.
