Verdict
The clearest difference is in-app purchases: WRI Dolphin at none against TerraWatch's 1. WRI Dolphin also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). TerraWatch's advantage is update cadence (every 5 days vs fortnightly). On price and ads there is nothing between them.
