Verdict
The clearest difference is price: 發Q at Free against Invoice Barcode's $0.99. 發Q also leads on review sentiment (40% vs 0%) and update cadence (every 4 weeks vs every 8 months). Invoice Barcode's advantage is ads (none vs shown). On in-app purchases and device support there is nothing between them.
