    Smart Runner▲94

    Ran my first marathon. Didn’t want to keep paying so much for Runna. So I built a running coach app, and then kept improving it more and more, i think it’s pretty good now. Give it a try and share your thoughts.

    Runo 2.0▲132

    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.
