Verdict
The clearest difference is review sentiment: FS8 at 64% against [solidcore]'s 21%. FS8 also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). [solidcore]'s advantage is rating (4.9 vs 4.1) and ratings volume (29K vs 23). On price, update cadence, in-app purchases and iOS requirement 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
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
[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 23, so its average is the more settled of the two. Written reviews complicate that: 21% of [solidcore]'s written reviews are positive against 64% of FS8's, so the app with the better star average is not the one people write more warmly about.
[solidcore] ships an update every 6 weeks, FS8 every 3 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
