# VHDL Compiler vs RISC

The clearest difference is rating: RISC at 5.0 against VHDL Compiler's 2.7. RISC also leads on in-app purchases (none vs 1) and ads (none vs shown). VHDL Compiler's advantage is ratings volume (7 vs 1) and iOS requirement (12.0 vs 26.0). On price, review sentiment and device support there is nothing between them.

Both are free to download. VHDL Compiler sells 1 one-off in-app purchase. RISC asks for nothing beyond the download.

RISC holds the better App Store score, 5.0 against 2.7. That said, the two scores are not equally well evidenced: VHDL Compiler has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

VHDL Compiler ships an update every 2 months, RISC every 2 weeks. The most recent releases landed on October 26, 2026 and October 1, 2026 respectively.
