# NGC vs Numis

The clearest difference is rating: Numis at 5.0 against NGC's 2.1. Numis also leads on update cadence (every 9 days vs every 2 months). NGC's advantage is in-app purchases (none vs 2) and ratings volume (78 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Numis sells 2 in-app purchases, starting at $4.99 per month. NGC asks for nothing beyond the download.

Numis holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: NGC has 78 ratings behind it against 1, so its average is the more settled of the two.

NGC ships an update every 2 months, Numis every 9 days. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
