Nice presentation and website, I was going to say no app needed for these, but then checked the stats and dashboard on your app landing page.

I followed the couch to 10k plan 5 years ago (without an app), and it worked well. Looking back, if I wanted an app, this is what I would like to have:

1. Apple watch notifications tell me when to walk, when to run, and how to maintain my pace. 2. Calories are fine, but having heart rate logs and how this is improving over time would be really good. 3. Any chance of VO2 Max calculation? Both Garmin and Apple Watch struggle with this. I know this can't be accurate before 6 months of training, but some indications about the progress would be helpful and motivating.

Good luck!
