Verdict
The clearest difference is in-app purchases: Authenticator at none against Sticky Notes HD's 1. Authenticator also leads on rating (5.0 vs 4.7) and chart position (#195 vs unranked). Sticky Notes HD's advantage is ratings volume (1.9K vs 3) and review sentiment (93% vs 75%). On price, update cadence, ads and device support 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
Sticky Notes HD costs $0.99 and Authenticator $0.99 up front. Sticky Notes HD sells 1 one-off in-app purchase. Authenticator asks for nothing beyond the download.
Authenticator holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sticky Notes HD has 1.9K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 93% of Sticky Notes HD's written reviews are positive against 75% of Authenticator's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 23, 2026 and September 7, 2026 respectively.
