iPhone 5s worked ok

First time out and the app froze when I started playing with the setting on the left side, strength, fish on or off. I restarted my phone and it worked good the rest of the day but I never played with the setting again.

It wound be nice if you could add something we can turn on to get a notice every two months that we need to charge our battery.
