Verdict
The clearest difference is in-app purchases: DFree Personal at none against URUOI's 3. DFree Personal also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). URUOI's advantage is update cadence (every 10 days vs every 4 weeks). On price and ads there is nothing between them.
