# Fasty vs Zero Fast

The clearest difference is review sentiment: Zero Fast at 100% against Fasty's 8%. Zero Fast also leads on update cadence (every 2 weeks vs every 9 months) and rating (5.0 vs 4.7). Fasty's advantage is ratings volume (1.5K vs 1) and iOS requirement (16.5 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fasty sells 3 in-app purchases, starting at $9.99 per 7 days and Zero Fast sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Zero Fast holds the better App Store score, 5.0 against 4.7. 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. Written reviews point the same way: 8% of Fasty's written reviews are positive against 100% of Zero Fast's.

Fasty ships an update every 9 months, Zero Fast every 2 weeks. The most recent releases landed on October 13, 2026 and October 3, 2026 respectively.
