Verdict

The call

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.
