Didn't work at first but quick update and it works perfectly. Makes a big difference having an audio hr zone alert. Thanks to the dev for quick fix. Just wish it had a widget now so I could use it as a small app overlaid on my interval timer.
Not working with Mio link
Exactly what i was looking for. A simple heart rate app with heart rate zones and audio queues when you enter and leave each zone. Easy to use interface, which isn't overloaded with settings or features that aren't needed. It's a shame this app is so hard to find, because it's the best one out there. Would happily pay money for this, but it's totally free! No adds either!
App doesn't see my generic Bluetooth monitor.
Does exactly what I need to when running, I can tailor my runs to a specific heart rate range and set myself targets based on what I want to achieve each time I go out, stops me from going out too slow/quick. Only gripe is the volume is always too quiet even with Android set on Max, job to hear it over music sometimes. Be nice if you could set a sweet spot or make your own range to squeeze your performance right to the edge.
