Auto Typer: Bluetooth Keyboard APP
Some examples of useful scripts to save typing time include: passwords, emails, urls, crypto wallet addresses, shell scripts.
The app operates by leveraging the Bluetooth HID feature available on devices running Android 9 or newer. This functionality enables the Android device to behave like a standard wireless keyboard connected through Bluetooth. As a result, it should be compatible with devices that supports Bluetooth keyboard connections, such as PCs, laptops, or phones.
