What is Coolmuster Android Assistant?
Coolmuster Android Assistant manages an Android phone or tablet from a Windows computer. It brings contacts, SMS, call logs, photos, music, videos, documents and apps into a desktop workflow, with local backup and restore alongside selective import and export. It suits keeping a computer copy of phone data or choosing individual files to move between the two devices.
The publisher documents contact editing, SMS composition and replies, media transfers, and batch app installation or removal. Devices can connect by USB or Wi-Fi, using a companion app on the phone. USB setup requires USB debugging; Wi-Fi setup requires the phone and computer to share the same network.
This is commercial desktop software, not an unrestricted free Android app. Coolmuster offers a free trial and paid one-year or lifetime licenses; the advertised individual licenses cover one PC, and the one-year option renews automatically unless cancelled. The alternative CoolTransfer phone companion does not support sending SMS or managing apps.
The gallery image shows the older 4.0.34 Windows interface, not the publisher-listed 6.4.56 release. The application and device compatibility have not been tested for this entry.
