# Billdu vs Invoice Maker + Estimate App

The clearest difference is ratings volume: Billdu at 26K against Invoice Maker + Estimate App's 95. Billdu also leads on chart position (#73 vs unranked). Invoice Maker + Estimate App's advantage is review sentiment (100% vs 90%) and iOS requirement (14.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Billdu sells 10 in-app purchases, starting at $7.99 per month and Invoice Maker + Estimate App sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
