Hi there. I'm the author of said tracker and am always happy to receive feedback. Thanks for promoting it! I also like chunter's tune a lot.
The rather unorthodox track ids are actually just the result of my trying to make the best of the phone screen. I know it's a bit weird but I couldn't think of something better at the time. 
The latency is quite a bummer but I know that there are ways to solve it. It's in the pipeline.
