Auto WiFi Tethering is a utility application designed for Android devices that transforms your smartphone into a wireless router for seamless internet sharing. This free app operates in the background, automatically activating WiFi tethering upon system startup, making it a convenient tool for users needing constant internet access on multiple devices. Key features include a widget for quick toggling, a scheduler for managing on/off times, and a SIM card whitelist to control costs.

The app offers advanced functionalities such as tethering activation based on Bluetooth or USB connections, monitoring data usage to prevent overages, and checking for active internet connections to maintain service. It also includes battery temperature monitoring to protect your device. Although it cannot operate on Android 5.0 and later due to system restrictions, Auto WiFi Tethering remains a robust solution for users seeking efficient internet sharing options.
