Quoting myself I've installed google play store on my Jolla and now tried the premium version of Sportstracker. All the different maps works and all the premium features are doing fine in sailfish. The one thing that doesn't seem to work is voice feedback...there's no voice triggered even if I click the lap-button. Voice feedback is available in the free version too. Has anyone found a way to make it work somehow? Otherwise the Sportstracker premium version works great. Ghost target is cool and the filters and goal settings are useful. I hope MeeRun adds similar features (voice feedback is already there and working )....I would certainly pay for it...I guess it might happen if Jolla ever makes the store open for paid apps.
