Prayer Walk Now

I’m looking for an app that can help me record prayer walks and evangelism conversations on my new mission field. I really like a couple of things about this app. I like how you can invite people to participate and I like how you can mark certain points on the map. But it falls so short from actually being functional. The app doesn’t track where you walk, just the points you choose to mark. And those points are just that: points. You can’t make any notes about what specifically you’re praying for. If they would add those two features, I can see this being a tool I would use for every team that comes to work with me. As is, it’s not functional as a prayer walking app.
