Verdict
The clearest difference is rating: GrapplApp at 4.4 against OneJitsu's 1.0. GrapplApp also leads on in-app purchases (none vs 7) and ratings volume (7 vs 1). OneJitsu's advantage is update cadence (every 4 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
