# Introvert vs Oki

The clearest difference is rating: Introvert at 4.7 against Oki's 4.4. Oki's advantage is review sentiment (64% vs 43%) and update cadence (every 4 days vs every 2 weeks). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Introvert sells 10 in-app purchases, starting at $6.99 per month and Oki sells 10 in-app purchases, starting at $1.00 per month. Whichever you choose, the download price is not the number that matters.

Introvert holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 822 and 385 respectively. Written reviews complicate that: 43% of Introvert's written reviews are positive against 64% of Oki's, so the app with the better star average is not the one people write more warmly about.

Introvert ships an update every 2 weeks, Oki every 4 days. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
