Verdict
The clearest difference is rating: Case Formatter at 5.0 against BLine Mobile's 4.5. Case Formatter also leads on monetization model (free vs free with in-app purchases) and update cadence (every 5 days vs every 3 weeks). BLine Mobile's advantage is ratings volume (8 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.
