In many ways it is (or was) a great app. with version 5.6 (Jan 2022) it quit effectively tracking steps/distance when walking. It's very frustrating to know a lap is 1.4 mile and some days the app shows .80 miles and other days it shows .9 miles ... And the GPS data simply comes and goes... some days it starts with the start of the lap... and goes 1000 steps and quits... other days it starts a 100 steps in... tracks a few hundred ... stops ... restarts and it looks like you've simply teleported parts of the walk. Please fix...
