Verdict
The clearest difference is rating: AiSecure2 at 3.0 against Qnotes3's 1.7. Qnotes3's advantage is ratings volume (15 vs 2) and review sentiment (10% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
AiSecure2 holds the better App Store score, 3.0 against 1.7. That said, the two scores are not equally well evidenced: Qnotes3 has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 10% of Qnotes3's written reviews are positive against 0% of AiSecure2's, so the app with the better star average is not the one people write more warmly about.
Qnotes3 ships an update every 3 months, AiSecure2 every 5 months. The most recent releases landed on June 19, 2026 and September 13, 2026 respectively.
