Verdict
The clearest difference is price: AKAI at Free against Cardinal Chains's $2.99. AKAI also leads on update cadence (every 3 weeks vs every 5 months) and iOS requirement (9.0 vs 15.6). Cardinal Chains's advantage is in-app purchases (none vs 3) and ratings volume (24 vs 2). On rating, ads and device support there is nothing between them.
