Wear Hotspot allows you to toggle your phone's tethering on from your Android Wear smartwatch
The app can be activated via verbally telling the watch to "open Wear Hotspot", or navigating to its icon and launching it manually. The latter may be necessary, since users have been commenting that their smartwatches often mistake the word "wear" for "where" and refuse to open the desired app. Developer Rabid App Design has promised to look into that.
Speaking of comments – the app is in its very early stages and so far there isn't a comprehensive list of what phones it works with. A lot of users have reported it to not function as desired on their smartphones. Still, the developers claim they are hard at work ironing out any bugs, and support for more devices should increase.
If you wish to test it, make sure that your provider has not placed any restrictions regarding tethering on your smartphone. Then, go ahead and download it from the link below. If any problems should arise – one shouldn't hesitate to contact Rabid App Design, as they seem determined to take customer support and feedback very seriously.
