I built Runo after years of inconsistent marathon training. GPS watches tell you your pace AFTER it's too late. So I made a simple metronome that plays a beat at your target cadence (steps per minute).

New in 2.0: Apple Watch haptics (run to the beat without headphones), Strava sync, and social features.

4.7 on App Store, 10k+ runners. Would love feedback from the HN community.
