I think Visions is very useful but for 200$/month plans I find it strange that improvements such as following are not made:
- Clear out all obvious bugs that the trainer is riddled with
- Proper hosting so the thing works smoothly for all the data
- Make a more serious effort expanding the library. More rivers, add in MW solutions.

The reason you can charge 200$ in spite of this is because of a duopoly market. It wouldn't hurt being preemptive before a competitor comes with a superior product which will not be that hard to make.
