Most of the time, the app was keeping the current settings when you were switching to answer a call or check your mails. But sometimes, it was loosing the current length of line calculation. Another case where this could be useful, is the cas where you are fishing 2 different divers to get to different depths.
At the end, it is more to remember where I intended to fish than the real length of line.
Anyway, now, the app keep track of your latest request and it’s cool.
