Verdict
The clearest difference is price: kineticSynth at Free against VADrum2's $14.99. kineticSynth also leads on rating (5.0 vs 4.5) and update cadence (every 3 weeks vs every 5 months). VADrum2's advantage is ratings volume (16 vs 2). On ads, in-app purchases and device support there is nothing between them.
