# purchasing.ai vs Billdu

The clearest difference is review sentiment: purchasing.ai at 100% against Billdu's 40%. purchasing.ai also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (13.0 vs 17.0). Billdu's advantage is rating (4.7 vs 3.4) and ratings volume (208 vs 5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. purchasing.ai sells 1 in-app purchase, starting at $99.99 per year and Billdu sells 12 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

Billdu holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: Billdu has 208 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of purchasing.ai's written reviews are positive against 40% of Billdu's, so the app with the better star average is not the one people write more warmly about.

purchasing.ai ships an update every 3 weeks, Billdu every 10 days. The most recent releases landed on September 17, 2026 and October 16, 2026 respectively.
