Verdict

The call

The clearest difference is ads: Rollog at none against Night Terrors's shown. Rollog also leads on update cadence (every 5 days vs every 2 months) and rating (4.5 vs 4.3). Night Terrors's advantage is review sentiment (75% vs 50%) and iOS requirement (13.0 vs 17.0). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
