Verdict
The clearest difference is in-app purchases: STUNLOCKER at none against SAGLY's 18. STUNLOCKER also leads on review sentiment (74% vs 46%) and iOS requirement (12.1 vs 16.0). SAGLY's advantage is rating (4.4 vs 4.0) and update cadence (every 5 days vs monthly). On price, ratings volume, 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
Both are free to download. SAGLY sells 18 in-app purchases, starting at $0.99 per month. STUNLOCKER asks for nothing beyond the download.
SAGLY holds the better App Store score, 4.4 against 4.0. Both are backed by a comparable volume of ratings — 24 and 60 respectively. Written reviews complicate that: 74% of STUNLOCKER's written reviews are positive against 46% of SAGLY's, so the app with the better star average is not the one people write more warmly about.
STUNLOCKER ships an update monthly, SAGLY every 5 days. The most recent releases landed on October 21, 2026 and October 30, 2026 respectively.
