# Safety Note+ Pro vs AI Ace

The clearest difference is price: AI Ace at Free against Safety Note+ Pro's $3.99. AI Ace also leads on update cadence (weekly vs fortnightly). Safety Note+ Pro's advantage is ads (none vs shown) and rating (4.8 vs 4.5). On review sentiment, in-app purchases and device support there is nothing between them.

AI Ace is free to download; Safety Note+ Pro costs $3.99 up front. Safety Note+ Pro sells 6 in-app purchases, starting at $0.99 per month and AI Ace sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Safety Note+ Pro holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Safety Note+ Pro has 743 ratings behind it against 39, so its average is the more settled of the two. Written reviews complicate that: 77% of Safety Note+ Pro's written reviews are positive against 80% of AI Ace's, so the app with the better star average is not the one people write more warmly about.

Safety Note+ Pro ships an update fortnightly, AI Ace weekly. The most recent releases landed on October 14, 2026 and September 30, 2026 respectively.
