Verdict

The call

The clearest difference is ratings volume: Billdu at 26K against Invoice Generator-Estimate App's 51. Billdu also leads on update cadence (every 2 weeks vs monthly) and chart position (#73 vs unranked). Invoice Generator-Estimate App's advantage is review sentiment (100% vs 90%) and iOS requirement (14.5 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Billdu sells 10 in-app purchases, starting at $7.99 per month and Invoice Generator-Estimate App sells 7 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Billdu holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Billdu has 26K ratings behind it against 51, so its average is the more settled of the two. Written reviews complicate that: 90% of Billdu's written reviews are positive against 100% of Invoice Generator-Estimate App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Billdu ships an update every 2 weeks, Invoice Generator-Estimate App monthly. The most recent releases landed on November 9, 2026 and November 3, 2026 respectively.
