I'd like to find an Android app that offers both heart rate monitoring and GPS navigation. By navigation I mean the feature of the Wikiloc app that guides you to follow a route. The problem with the Wikiloc app itself is that as far as I know it doesn't include heart rate monitoring, and that is absolutely essential for me.
Currently I'm using Sports Tracker, which works great for the heart rate monitoring, but doesn't have any navigation features.
I'm so happy with this website, but right now the only way I have to follow the routes is trying to learn them by heart (which never works, I always get lost halfway

).
So, do you know of any Android app that has both features? I don't mind paying a reasonable price for it.
