Verdict
The clearest difference is review sentiment: Cryptobox at 100% against Obsidian's 62%. Cryptobox also leads on rating (5.0 vs 4.5). Obsidian's advantage is ratings volume (2.7K vs 1) and update cadence (every 3 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
