Verdict

The call

The clearest difference is in-app purchases: handEye at none against TopGuru's 30. handEye also leads on review sentiment (50% vs 29%). TopGuru's advantage is ratings volume (412 vs 6) and rating (3.5 vs 3.2). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

TopGuru holds the better App Store score, 3.5 against 3.2. That said, the two scores are not equally well evidenced: TopGuru has 412 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 50% of handEye's written reviews are positive against 29% of TopGuru's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

handEye ships an update every 3 months, TopGuru every 3 weeks. The most recent releases landed on October 9, 2026 and October 20, 2026 respectively.
