# VHDL Compiler vs Logic

The clearest difference is review sentiment: VHDL Compiler at 100% against Logic's 21%. VHDL Compiler also leads on iOS requirement (12.0 vs 15.1). Logic's advantage is rating (3.6 vs 2.7) and in-app purchases (none vs 1). On price, ratings volume, update cadence and ads there is nothing between them.

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

Logic holds the better App Store score, 3.6 against 2.7. Both are backed by a comparable volume of ratings — 7 and 7 respectively. Written reviews complicate that: 100% of VHDL Compiler's written reviews are positive against 21% of Logic's, so the app with the better star average is not the one people write more warmly about.

VHDL Compiler ships an update every 2 months, Logic every 5 weeks. The most recent releases landed on October 11, 2026 and October 12, 2026 respectively.
