Verdict

The call

The clearest difference is in-app purchases: Leo3 Smart at none against UWACAM's 3. Leo3 Smart also leads on rating (5.0 vs 4.7) and device support (3 vs 1). UWACAM's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (55 vs 1). On price and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Leo3 Smart holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: UWACAM has 55 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Leo3 Smart's written reviews are positive against 70% of UWACAM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Leo3 Smart ships an update every 3 months, UWACAM every 2 weeks. The most recent releases landed on October 3, 2026 and October 19, 2026 respectively.
