Verdict
The clearest difference is in-app purchases: Induction at none against Bolus's 2. Induction also leads on update cadence (every 5 days vs fortnightly). Bolus's advantage is ratings volume (10 vs 1) and iOS requirement (15.1 vs 18.0). On price, rating, ads and device support there is nothing between them.
