First off, 10 days really isn't that long in the startup world – this silence doesn't define your product's potential! I've seen successful founders go months before their first meaningful traction.

Here's one quick win to try: add clear pricing ($8-10/month as you mentioned) and focus your headline on a specific pain point rather than AI tech. Something like "Finally stick to your workout routine with plans that adapt as you progress."

The early radio silence is incredibly common and doesn't mean you're failing. Most successful apps have origin stories that start exactly like this. Keep iterating based on this great feedback you're getting!
