Verdict

The call

The clearest difference is rating: Ultra Boost at 5.0 against ThinkDiag+'s 4.5. Ultra Boost also leads on review sentiment (100% vs 74%) and monetization model (free vs free with in-app purchases). ThinkDiag+'s advantage is ratings volume (4.3K vs 4) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.
