# Engineering AI vs Home.AI

The clearest difference is price: Home.AI at Free against Engineering AI's $3.99. Home.AI also leads on ratings volume (326 vs 1) and update cadence (every 3 days vs every 9 days). Engineering AI's advantage is rating (5.0 vs 4.8). On ads, in-app purchases and device support there is nothing between them.

Home.AI is free to download; Engineering AI costs $3.99 up front. Engineering AI sells 3 one-off in-app purchases and Home.AI sells 1 in-app purchase, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Engineering AI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Home.AI has 326 ratings behind it against 1, so its average is the more settled of the two.

Engineering AI ships an update every 9 days, Home.AI every 3 days. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
