Verdict

The call

The clearest difference is rating: Smart Keys at 4.6 against Unlock's 4.0. Smart Keys also leads on device support (3 vs 1). Unlock's advantage is update cadence (every 6 days vs every 3 weeks) and review sentiment (58% vs 43%). On price, ads, in-app purchases and monetization model 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

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Smart Keys sells 10 in-app purchases, starting at $4.99 per 7 days and Unlock sells 10 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Smart Keys holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Unlock has 3.5K ratings behind it against 536, so its average is the more settled of the two. Written reviews complicate that: 43% of Smart Keys's written reviews are positive against 58% of Unlock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Smart Keys ships an update every 3 weeks, Unlock every 6 days. The most recent releases landed on November 12, 2026 and November 13, 2026 respectively.
