Verdict
The clearest difference is price: LinuxCmdQ&A at Free against Prepware CFI's $9.99. LinuxCmdQ&A also leads on rating (3.0 vs 2.4) and iOS requirement (12.1 vs 15.0). Prepware CFI's advantage is ads (none vs shown) and review sentiment (32% vs 0%). On in-app purchases and device support there is nothing between them.

LinuxCmdQ&A is free to download; Prepware CFI costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
LinuxCmdQ&A holds the better App Store score, 3.0 against 2.4. That said, the two scores are not equally well evidenced: Prepware CFI has 37 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 32% of Prepware CFI's written reviews are positive against 0% of LinuxCmdQ&A's, so the app with the better star average is not the one people write more warmly about.
Prepware CFI ships an update every 4 months, LinuxCmdQ&A every 44 months. The most recent releases landed on September 22, 2026 and June 11, 2026 respectively.
