Verdict
The clearest difference is rating: NebulaBuds at 4.4 against MasTrack's 2.3. NebulaBuds also leads on ratings volume (16K vs 20) and update cadence (every 2 weeks vs every 6 weeks). MasTrack's advantage is in-app purchases (none vs 10) and iOS requirement (9.0 vs 14.0). On price, ads and device support there is nothing between them.
