# BodyFast vs Zero Fast

The clearest difference is review sentiment: Zero Fast at 100% against BodyFast's 42%. Zero Fast also leads on rating (5.0 vs 4.7) and update cadence (every 2 weeks vs every 5 weeks). BodyFast's advantage is ratings volume (146K vs 1) and iOS requirement (15.1 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. BodyFast sells 13 in-app purchases, starting at $8.49 per month and Zero Fast sells 2 in-app purchases, starting at $3.99 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: BodyFast has 146K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 42% of BodyFast's written reviews are positive against 100% of Zero Fast's.

BodyFast ships an update every 5 weeks, Zero Fast every 2 weeks. The most recent releases landed on October 31, 2026 and October 30, 2026 respectively.
