This apps single purpose is to notify, in case, your radio dies.
This is why I made this app:
My current mobile phone provider dialog.lk has a quite bad network.
Especially in crowded areas, the signal just breaks silently.
No calls/messages/data go through anymore.
There is no notification.
The only thing that helps, is to reboot the phone.
If you have bad luck, you only notice it after hours.
So this app tries to check the signal on connection loss.
If there is no signal, it will periodically ring and/or vibrate.
Please write an email, or create an issue on the app's website if it's not working on your phone.
