Verdict
The clearest difference is update cadence: Twos at daily against WaterDo's fortnightly. Twos also leads on rating (4.8 vs 4.5) and review sentiment (90% vs 71%). WaterDo's advantage is ratings volume (1.2K vs 392) and iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.
