Verdict

The call

The clearest difference is price: Obsidian at Free against EisenPlan's $0.99. Obsidian also leads on chart position (#125 vs unranked) and iOS requirement (15.6 vs 17.0). EisenPlan's advantage is update cadence (every 3 days vs every 3 weeks). On ads, in-app purchases and device support there is nothing between them.
