Verdict
The clearest difference is rating: Time Timer at 4.6 against Boom Cards's 2.5. Time Timer also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (15K vs 4). Boom Cards's advantage is in-app purchases (none vs 1) and iOS requirement (13.0 vs 16.0). On price, ads and device support there is nothing between them.
