Best running app for Apple Watch


I think I’ve tried all of the running apps available for Apple Watch out there and this is definitely the best. One of the major features for me is the ability to use the phone GPS (which in my testing is still more accurate than the GPS in my AW2), but I can also use the Watch GPS stand alone if I need to. Then there are the customisable Watch fields and audio cues as well as the ability to record the weather and other data and post all of this to various apps like Strava and Nike+. It all works great and is very accurate and consistent.

Ideally needs a few extra things like a complication from the Watch and the ability to use Watch held music so it can be truly stand alone but these are minor.

Loved this before the recent update


This is my go to app for running. Stable and accurate tracking, customisation, coaching and the ability to upload runs to various other fitness apps made it my number one choice. However hate the voice change to the coaching in the recent update. Went from a great motivating cheerleader to a robot. Totally not motivating at all. In fact makes me want to switch to another app! Can we have the old voice back please??!! Also would be great if they could fix the bug which means that whatever you’re listening to completely cuts out when the robot voice comes in!

I have been a loyal user of ismoothrun having used it exclusively to track my running fir 6 years. But with the release of version 6 it seems to be fraught with issues.

Previously I never had any problems with the gps, communications to to Apple Watch or the touch on the Watch.

But now the touch works sporadically, if I use iPhone + Watch mode then pausing can take several attempts and I now hardly ever have a run when it doesn't drop from gps to use the pedometer causing sections of the route to be missing on the maps for any upload

I've been hoping that recent releases would fix these issues but I have now got so frustrated waiting I have decided to call it a day with ismoothrun

I also think the philosophy of keeping everything local is past its time. Syncing to iCloud to allow sync to ismoothrun on another device would be useful without having to do a complete device restore from backup
