Verdict

The call

The clearest difference is price: MarsText at Free against Phone Blocker's $1.99. MarsText also leads on iOS requirement (9.0 vs 17.0). Phone Blocker's advantage is ads (none vs shown) and update cadence (every 2 months vs every 5 months). On in-app purchases and device support there is nothing between them.
