Verdict
The clearest difference is review sentiment: Kainy at 100% against DS finder's 26%. Kainy also leads on rating (4.0 vs 2.5) and update cadence (every 3 weeks vs every 4 months). DS finder's advantage is in-app purchases (none vs 1) and ratings volume (123 vs 4). On price, ads and device support there is nothing between them.
