Verdict

The call

The clearest difference is monetization model: QI at freemium against Invoice Estimate Maker's subscription. QI also leads on update cadence (weekly vs monthly) and iOS requirement (13.0 vs 15.2). Invoice Estimate Maker's advantage is review sentiment (97% vs 63%) and rating (4.9 vs 4.6). On price, ads, in-app purchases and device support there is nothing between them.
