I've been helping the author with testing and suggesting improvements. He has been very helpful. It's gradually evolving into what I had wanted for an OSM mapping tool. It can use OSM tiles so you can see what is already mapped.

I have some issues with my position lagging behind my actual location. This may be due to my old Acer n35 being a bit slow, but he's looking at improving performance. I can run Tomtom and other GPS apps, so it should be possible.

My latest request is for more control over the rate of logging. I think that it should be dynamic, taking distance covered and change in heading into account. He's working on that too.

There's a page on the wiki for the application with a wish list.
