that's correct! I'm just beginning so I haven't done anything definitive or deep yet. The best motivation is the person themselves, but my thought is that if the app clearly defines an easy to follow training plan that outlines progress, it will be more exciting to keep going. Additionally, push notifications could help nudge the rider as well.
I started riding last year and I loved every minute of it, although admittedly I'm struggling with motivation to ride indoors in the winter! Anyways, I was trying to think about what would have helped me see my progress and stay motivated to keep improving. Riding was never the problem for me, instead it was hard to know how to get better. Research was hard because of too many sources, opinions, etc. I just signed up for my first century, so for now that's my goal!
I'm seeing if others have similar experiences that I did and hopefully I can develop something that stands out from there!
