# SwiftSize vs Daikin Tech Hub

The clearest difference is price: Daikin Tech Hub at Free against SwiftSize's $9.99. Daikin Tech Hub also leads on rating (4.6 vs 4.0) and update cadence (every 6 weeks vs every 10 months). On review sentiment, ads, in-app purchases and device support there is nothing between them.

Daikin Tech Hub is free to download; SwiftSize costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Daikin Tech Hub holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Daikin Tech Hub has 3.6K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 33% of SwiftSize's written reviews are positive against 27% of Daikin Tech Hub's, so the app with the better star average is not the one people write more warmly about.

SwiftSize ships an update every 10 months, Daikin Tech Hub every 6 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
