Verdict

The call

The clearest difference is in-app purchases: BitSpinner at none against ACT Math's 1. BitSpinner also leads on update cadence (every 4 months vs every 12 months). ACT Math's advantage is iOS requirement (15.0 vs 26.0). On price, ads and device support there is nothing between them.
