Could and should be better

Signal alert has secondary functionality to signal when battery is low, by vibrating and sending a popup notice. The fact that these signals also appear when the device is charging doesnt give confidence about the quality for the remaining parts of the application. I cant find any use why to signal that battery is low when being charged.

The WiFi/Signal alert function also has the habit of sending more notifications than is good. Especially in edge cases where there is no signal and a few seconds later there is signal again. Notifications every second are pointless too.

Request to the developer is to add a lot of user preferences to let the user control when notifications are sent and when not. And no, signaling low battery when charging is not a candidate for a user preference. User preferences could be:
- enable/disable location based services (i didnt find any reason why the current app version needs any location based capabilities)
- custom battery alert levels (3%, 5%, 10% would be of my interest, not 50%)
- no (gsm) signal messages within: (a) ... seconds/minutes (5) and/or (b) ... meters/miles (100) when using location service (dont notify too often)
- enable/disable gsm signal alert (when I would only want WiFi or battery alerts)
- action to take when entering WiFi range: (enable airplane mode) [priority: low]
- action to take when leaving WiFi range: (disable airplane mode) [priority: low]
- or at least open the phones general settings instead of signal alert app when tapping on a WiFi alert message, to quickly turn wifi/airplane on/off [priority: low]
- number of alert repeats (when out of range and another signal might be available == airplane mode enabled or wifi disabled), interval (time) between repeats
