Verdict
The clearest difference is review sentiment: ChalkTimer at 100% against Arbiter's 32%. ChalkTimer also leads on rating (5.0 vs 4.4) and update cadence (every 6 days vs fortnightly). Arbiter's advantage is ratings volume (1.2K vs 2) and chart position (#77 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
