# PerfectFast vs Nomu

The clearest difference is in-app purchases: PerfectFast at none against Nomu's 6. PerfectFast also leads on review sentiment (100% vs 86%). Nomu's advantage is ratings volume (97 vs 8) and update cadence (every 5 days vs every 10 days). On price, rating, ads and monetization model there is nothing between them.

Both are free to download. Nomu sells 5 in-app purchases, starting at $2.99 per 7 days. PerfectFast asks for nothing beyond the download.

PerfectFast holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Nomu has 97 ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 100% of PerfectFast's written reviews are positive against 86% of Nomu's.

PerfectFast ships an update every 10 days, Nomu every 5 days. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
