I for one would happily subscribe for those additional features. As an ageing technophobe, I think the app is reasonably intuitive to use and I very much appreciate the flexibility it gives me.
I don't know if a waypoint alert would fall into the subscription bracket, but it would be a real bonus to have that alongside the off route alert that already exists - especially for someone who does a lot of night running...
Thanks for the great work you doing.
Waypoint alerts are definitely on my list of features to add. I will probably add them when I upgrade the route functionality to allow features such as waypoint creation and turn-by-turn navigation.
I expect that the waypoint alerts and creation will be included in the standard app, whereas the turn-by-turn navigation will be part of a subscription because it will probably require the app to use a paid service to create directions from a route.
Thanks for your kind words about the app!
