# SIMO vs gcc

The clearest difference is price: gcc at Free against SIMO's $4.99. gcc also leads on review sentiment (100% vs 58%). SIMO's advantage is update cadence (every 3 weeks vs every 7 months) and ratings volume (55 vs 1). On ads, in-app purchases, device support and iOS requirement there is nothing between them.

gcc is free to download; SIMO costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

SIMO holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: SIMO has 55 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 58% of SIMO's written reviews are positive against 100% of gcc's, so the app with the better star average is not the one people write more warmly about.

SIMO ships an update every 3 weeks, gcc every 7 months. The most recent releases landed on August 17, 2026 and June 4, 2026 respectively.
