# Invoice Maker vs Authenticator

The clearest difference is ads: Authenticator at none against Invoice Maker's shown. Authenticator also leads on ratings volume (61 vs 7). Invoice Maker's advantage is update cadence (every 3 days vs every 5 months) and rating (4.9 vs 4.6). On price, in-app purchases, monetization model and device support 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 Authenticator sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Invoice Maker holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Authenticator has 61 ratings behind it against 7, so its average is the more settled of the two.

Invoice Maker ships an update every 3 days, Authenticator every 5 months. The most recent releases landed on October 1, 2026 and October 5, 2026 respectively.
