Verdict

The call

The clearest difference is ads: SuppaLog at none against StackDay's shown. SuppaLog also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). StackDay's advantage is update cadence (every 3 days vs every 2 weeks) and ratings volume (5 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
