Verdict

The call

The clearest difference is review sentiment: Head Tracker at 70% against RhyLive's 0%. Head Tracker also leads on rating (4.1 vs 3.7) and ratings volume (62 vs 6). RhyLive's advantage is in-app purchases (none vs 1) and update cadence (every 2 days vs fortnightly). On price, ads and device support there is nothing between them.
