When I built the trip meters into the app I started with just one, because at the time I thought that’s all I’d need. Not long after I started testing it I realised that I could see how long the first leg of my journey was but unless I made a not somewhere I couldn’t see how long the return leg was, just the total distance, when I got back.

So then I decided to build in a couple more trip meters which could all be reset independently, giving me the ability to record the distance for three legs of my journey (although in my case I’m really only interested in there and back).

You can reset the currently displayed trip meter by long-pressing it. The other trip meters will be unaffected.
