# Not Not 2 vs Linko

The clearest difference is rating: Not Not 2 at 4.7 against Linko's 3.8. Not Not 2 also leads on update cadence (every 2 weeks vs every 4 weeks) and ratings volume (81 vs 26). Linko's advantage is review sentiment (61% vs 51%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Not Not 2 sells 1 one-off in-app purchase and Linko sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Not Not 2 holds the better App Store score, 4.7 against 3.8. Both are backed by a comparable volume of ratings — 81 and 26 respectively. Written reviews complicate that: 51% of Not Not 2's written reviews are positive against 61% of Linko's, so the app with the better star average is not the one people write more warmly about.

Not Not 2 ships an update every 2 weeks, Linko every 4 weeks. The most recent releases landed on October 27, 2026 and October 30, 2026 respectively.
