# Fastin vs Air Workouts

The clearest difference is rating: Fastin at 4.8 against Air Workouts's 3.8. Fastin also leads on ratings volume (10K vs 5). Air Workouts's advantage is monetization model (free with in-app purchases vs subscription) and review sentiment (50% vs 33%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Fastin sells 8 in-app purchases, starting at $6.99 per 7 days and Air Workouts sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Fastin holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Fastin has 10K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 33% of Fastin's written reviews are positive against 50% of Air Workouts's, so the app with the better star average is not the one people write more warmly about.

Fastin ships an update every 3 weeks, Air Workouts weekly. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
