Verdict

The call

The clearest difference is price: Karamba at Free against Doo's $4.99. Karamba also leads on rating (5.0 vs 4.4) and iOS requirement (14 vs 17.6). Doo's advantage is ratings volume (39 vs 1) and update cadence (every 2 weeks vs every 2 months). On ads, in-app purchases and device support there is nothing between them.
