Good app! Some quick wins below...

Hi! Im a fresh user of this app that really satisfies my need.
In fact, I want to be informed of any signal loss because I am on-call for professional reason and cannot afford to miss any call.
I do not use logs and locations but this could be helpful according to your use of the app.
Two quick wins that could be added according to me :
1/ It would be great to be informed of signal loss even when connected to WiFi. I really look forward to seeing this improvement and hope a solution will be found soon.
2/ It would also be great to be able to change the alert : the simple SMS tone is too short and I am worried I could miss it if iPhone was in my pocket for instance. The possibility to change for a longer ringtone, or alert that doesnt stop until it is cutoff would be perfect.
