ReceptionRating · Positive reviews · Number of ratings

Fence.io holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: String.io has 1.8K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 0% of Fence.io's written reviews are positive against 58% of String.io's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Fence.io ships an update every 42 months, String.io every 3 months. The most recent releases landed on September 18, 2026 and October 2, 2026 respectively.
