Verdict
The clearest difference is in-app purchases: Optimal° at none against Lockly Home's 27. Optimal° also leads on rating (4.9 vs 4.6). Lockly Home's advantage is update cadence (every 2 weeks vs every 5 months) and ratings volume (1.7K vs 7). On price, review sentiment, 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. Lockly Home sells 27 in-app purchases, starting at $1.99 per month. Optimal° asks for nothing beyond the download.
Optimal° holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Lockly Home has 1.7K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 60% of Optimal°'s written reviews are positive against 62% of Lockly Home's, so the app with the better star average is not the one people write more warmly about.
Optimal° ships an update every 5 months, Lockly Home every 2 weeks. The most recent releases landed on September 29, 2026 and October 15, 2026 respectively.
