What’s one fitness feature that would genuinely improve consistency but doesn’t exist yet?

I’ve been exploring ideas around building smarter add-ons for Strava and smartwatch apps, especially features that go beyond tracking and actually help people stay consistent.

Most fitness apps are great at collecting data such as pace, heart rate, distance — but they don’t always help on low-motivation days or prevent burnout.

From a product perspective, I’m curious:

• What’s a feature you wish existed that would actually change your behaviour?

• What would make you open the app daily?

• What insight or nudge would feel valuable enough to pay for?

Personally, I think predictive insights (like injury risk or race readiness) are more compelling than badges, but I’d love to hear what this community thinks.

Would appreciate thoughts from builders, runners, and anyone working on health tech.
