Verdict

The call

The clearest difference is rating: charge7 at 5.0 against Tab's 4.2. charge7 also leads on review sentiment (100% vs 66%). Tab's advantage is ratings volume (1.1K vs 1) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.
