SwiftSize is an HVAC (heating, ventilation, and air conditioning) load calculator for residences. It is designed to very quickly measure off a home's exposures "on the fly" and produce accurate results for sizing heating and air conditioning equipment. Now generates a shareable PDF Report! It is designed to minimize the on-site engineering time required by the HVAC professional. Less time engineering means more one-on-one time with the customer! HVAC heat loads can be a cumbersome and time consuming and tend to distract from time spent consulting. SwiftSize addresses this problem by allowing complete heat loads to be performed in mere minutes. If it takes you more than 10 minutes with SwiftSize you're doing something wrong! SwiftSize is not a comprehensive room-by-room heat loss/heat gain/CFM calculator. If it were it would be SlowSize! It's intended for the equipment changeout market, not the new construction market.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
