Best 10k app available

Ive tried a few, so far this is the best Ive found. However, it does not track mileage so I have to run another app with it. Ive had issues with the volume as well, so I have to keep an eye on the app as to when Im supposed to walk and run because I cant always hear the voice. But I still prefer this app over the others.
