I was making a track while walking & my phone died. Fortunately I always have a spare battery or two, so I was back up within a minute or so, but it seems that ModRana wasn't saving my track so I lost it. Previously when I used Mappero in the same situation, the app kept my previous track & started tracking as soon as I started it, which is what I had hoped ModRana would have done. Is there anyway I can have it do that next time?
