# Nula vs Otay

The clearest difference is review sentiment: Otay at 100% against Nula's 50%. Otay also leads on update cadence (every 3 weeks vs every 2 months) and device support (3 vs 1). Nula's advantage is in-app purchases (none vs 5) and rating (4.4 vs 4.2). On price, ads and iOS requirement there is nothing between them.

Both are free to download. Otay sells 5 in-app purchases, starting at $3.99 per month. Nula asks for nothing beyond the download.

Nula holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 18 and 5 respectively. Written reviews complicate that: 50% of Nula's written reviews are positive against 100% of Otay's, so the app with the better star average is not the one people write more warmly about.

Nula ships an update every 2 months, Otay every 3 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
