Verdict
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.

Both are free to download. Night Terrors sells 3 in-app purchases, starting at $5.99 per month and Rollog sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Rollog holds the better App Store score, 4.5 against 4.3. Both are backed by a comparable volume of ratings — 8 and 4 respectively. Written reviews complicate that: 75% of Night Terrors's written reviews are positive against 50% of Rollog's, so the app with the better star average is not the one people write more warmly about.
Night Terrors ships an update every 2 months, Rollog every 5 days. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
