Best of design, features, and stability – iSmoothRun Review

ISR is constantly updated to use the latest sensors and iPhone/Apple watch features. With its interval planner, it is so easy to plan out your workout to the last minute. ISR's GPS tracking is also better than any other app I've tried. When on my bike, other apps have a snap to road tendency that makes my bike rides a bit wonky looking. Finally, ISR just works better with all the Bluetooth sensors and external displays (like the Wahoo RFLKT and Magellan Echo) that I use. Other apps have difficulty connecting and dropped connections that I don't find with ISR. These days almost any app can track your run/bike/hike workout, but ISR gives you fine tuned control and rock solid stability that will keep you coming back to this app.
