The call

ReceptionRating · Positive reviews · Number of ratings

[solidcore] holds the better App Store score, 4.9 against 4.1. That said, the two scores are not equally well evidenced: [solidcore] has 29K ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 21% of [solidcore]'s written reviews are positive against 67% of FS8's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

[solidcore] ships an update every 6 weeks, FS8 every 4 weeks. The most recent releases landed on October 14, 2026 and September 30, 2026 respectively.
