Verdict

The call

The clearest difference is in-app purchases: Aurisper at none against Nimbus8's 2. Aurisper also leads on rating (5.0 vs 4.8) and iOS requirement (17.0 vs 26.0). Nimbus8's advantage is update cadence (every 2 days vs every 6 days) and ratings volume (6 vs 1). On price, ads and device support there is nothing between them.
