Verdict
The clearest difference is review sentiment: Lockin Smart at 43% against Arpha's 10%. Lockin Smart also leads on update cadence (fortnightly vs every 7 months). Arpha's advantage is rating (3.5 vs 3.2) and iOS requirement (13.0 vs 15.1). On price, ratings volume, 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.
Arpha holds the better App Store score, 3.5 against 3.2. Both are backed by a comparable volume of ratings — 30 and 24 respectively. Written reviews complicate that: 10% of Arpha's written reviews are positive against 43% of Lockin Smart's, so the app with the better star average is not the one people write more warmly about.
Arpha ships an update every 7 months, Lockin Smart fortnightly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
