# Nomu vs JustFast

The clearest difference is in-app purchases: JustFast at none against Nomu's 6. JustFast also leads on rating (5.0 vs 4.8). Nomu's advantage is ratings volume (95 vs 1) and update cadence (every 5 days vs fortnightly). On price, 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. JustFast asks for nothing beyond the download.

JustFast holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Nomu has 95 ratings behind it against 1, so its average is the more settled of the two.

Nomu ships an update every 5 days, JustFast fortnightly. The most recent releases landed on October 18, 2026 and October 14, 2026 respectively.
