# Invoice Maker vs Wonder DOC

The clearest difference is ads: Wonder DOC at none against Invoice Maker's shown. Invoice Maker's advantage is update cadence (every 3 days vs every 2 months) and ratings volume (25 vs 2). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Invoice Maker sells 4 in-app purchases, starting at $8.99 per 7 days and Wonder DOC sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Wonder DOC holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Invoice Maker has 25 ratings behind it against 2, so its average is the more settled of the two.

Invoice Maker ships an update every 3 days, Wonder DOC every 2 months. The most recent releases landed on October 24, 2026 and October 10, 2026 respectively.
