Verdict

The call

The clearest difference is price: PickColor at Free against UnitFlowPro's $1.99. PickColor also leads on ads (none vs shown). UnitFlowPro's advantage is review sentiment (100% vs 75%) and update cadence (every 5 days vs every 2 weeks). On in-app purchases, device support and iOS requirement there is nothing between them.
