# Selbuk vs QI

The clearest difference is update cadence: QI at weekly against Selbuk's every 5 weeks. QI also leads on rating (4.6 vs 4.4). Selbuk's advantage is review sentiment (75% vs 63%). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Selbuk sells 2 in-app purchases, starting at $2.99 per month and QI sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

QI holds the better App Store score, 4.6 against 4.4. Both are backed by a comparable volume of ratings — 24 and 22 respectively. Written reviews complicate that: 75% of Selbuk's written reviews are positive against 63% of QI's, so the app with the better star average is not the one people write more warmly about.

Selbuk ships an update every 5 weeks, QI weekly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
