Verdict
The clearest difference is price: Relative Motion Technique at Free against Ballet Index's $0.99. Relative Motion Technique also leads on rating (5.0 vs 2.3) and update cadence (every 2 weeks vs every 3 months). Ballet Index's advantage is in-app purchases (none vs 7) and ratings volume (6 vs 1). On ads, device support and iOS requirement there is nothing between them.
