# SLAM! vs 538

The clearest difference is review sentiment: SLAM! at 67% against 538's 22%. SLAM! also leads on ads (none vs shown) and monetization model (free vs ad-supported). 538's advantage is rating (4.9 vs 4.5) and ratings volume (60 vs 4). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

538 holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: 538 has 60 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of SLAM!'s written reviews are positive against 22% of 538's, so the app with the better star average is not the one people write more warmly about.

SLAM! ships an update every 3 months, 538 monthly. The most recent releases landed on September 18, 2026 and September 10, 2026 respectively.
