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 1.6. That said, the two scores are not equally well evidenced: Qsync Pro has 12 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 17% of Qsync Pro'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.
Qsync Pro ships an update every 2 months, AiSecure2 every 5 months. The most recent releases landed on September 22, 2026 and September 13, 2026 respectively.
