Verdict
The clearest difference is rating: Fasty at 4.7 against LadyFast's 1.0. Fasty also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (1.5K vs 1). LadyFast's advantage is update cadence (every 3 weeks vs every 9 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Fasty sells 3 in-app purchases, starting at $9.99 per 7 days and LadyFast sells 2 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.
Fasty holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Fasty has 1.5K ratings behind it against 1, so its average is the more settled of the two.
Fasty ships an update every 9 months, LadyFast every 3 weeks. The most recent releases landed on October 25, 2026 and October 1, 2026 respectively.
