Your app looks like a weak vitamin, not a pain killer.
Looking at website, appstore screenshots and descriptions I got a relatively vague, generic and weak message "train smarter".
- What's in it for me?
- What exactly would I gain by wasting my time, focus and money on yet another AI gimmick?
- Who is this app made for exactly (professional athletes, lazy bums like me, weight loss enthusiasts, amateur bodybuilders, powerlifters, those dreaming of winning iron man...)?
I don't read any good and specific answers on these questions (even if I for a moment forget that 99% of amateur training success is just about consistency not "smartness") and don't want to even bother installing the app.
This is what b2c PMF is about - about the fit (the click) in user's head.
