Verdict
The clearest difference is in-app purchases: SIPLAP at none against OffBlock's 4. SIPLAP also leads on rating (5.0 vs 4.8). OffBlock's advantage is ratings volume (104 vs 1) and update cadence (every 2 months vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.
