The clearest difference is price: T at Free against Spam Call Block Pro's $3.99. T also leads on rating (4.7 vs 1.0) and update cadence (every 4 months vs every 39 months). Spam Call Block Pro's advantage is iOS requirement (10.0 vs 13.0). On ads, in-app purchases and device support there is nothing between them.
