# Nerva vs Open

Nerva and Open both sit at 4.7 stars, but that hides the real split: 72% of Nerva's written reviews are positive against 60% of Open's. Nerva also leads on iOS requirement (15.1 vs 17.0). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. Nerva sells 4 in-app purchases, starting at $99.00 per month and Open sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

Open holds the better App Store score, 4.9 against 4.7. Both are backed by a comparable volume of ratings — 15K and 18K respectively. Written reviews complicate that: 72% of Nerva's written reviews are positive against 60% of Open's, so the app with the better star average is not the one people write more warmly about.

Nerva ships an update every 8 days, Open weekly. Both last shipped on October 26, 2026.
