iSmoothRun
authentic ratingIt used to be a favorite app for running and tracking thanks to flexible interval setup, audio cues for heart rate zones, and a decade-long training archive. Now the main trouble is that it has fallen behind iOS and watchOS updates: on Apple Watch it freezes mid-run and loses all the data, and the sound has become barely audible. The final blow is that the developer stopped answering emails and hasn't shipped an update in a year.
The reviews are long and extremely specific: people have used it for ten years, mention a Stryd foot pod, a Polar sensor, Apple Watch Ultra 2, exact freeze behavior at mile 1-2. The 5-stars also have detail. Clearly a real long-standing audience.
