Verdict

The call

The clearest difference is ratings volume: Billdu at 26K against Invoice Maker's 1. Billdu also leads on update cadence (every 2 weeks vs every 5 weeks) and chart position (#81 vs unranked). Invoice Maker's advantage is review sentiment (100% vs 90%) and iOS requirement (15.0 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
