Verdict

The call

UUID and UU both sit at 5.0 stars, but that hides the real split: 100% of UU's written reviews are positive against 50% of UUID's. UUID's advantage is price (Free vs $0.99) and update cadence (every 2 months vs every 21 months). On rating, ratings volume, ads and in-app purchases there is nothing between them.
