Verdict
The clearest difference is review sentiment: Slabline at 100% against Beckett Mobile's 9%. Slabline also leads on rating (5.0 vs 4.5) and ads (none vs shown). Beckett Mobile's advantage is ratings volume (3.1K vs 6) and chart position (#156 vs unranked). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Beckett Mobile sells 11 in-app purchases, starting at $6.99 per month and Slabline sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Slabline holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Beckett Mobile has 3.1K ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 9% of Beckett Mobile's written reviews are positive against 100% of Slabline's.
Beckett Mobile ships an update every 6 weeks, Slabline every 11 days. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
