Verdict

The call

The clearest difference is rating: Titrate at 5.0 against Stackr's 4.4. Titrate also leads on review sentiment (100% vs 67%) and iOS requirement (15.1 vs 17.0). Stackr's advantage is update cadence (every 4 days vs every 11 days) and ratings volume (191 vs 18). On price, ads, in-app purchases and monetization model there is nothing between them.
