# Invoice Simple vs Wave

The clearest difference is rating: Invoice Simple at 4.9 against Wave's 4.4. Invoice Simple also leads on review sentiment (64% vs 29%) and ratings volume (123K vs 6.7K). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Invoice Simple sells 9 in-app purchases, starting at $6.99 per month and Wave sells 4 in-app purchases, starting at $8.00 per month. Whichever you choose, the download price is not the number that matters.

Invoice Simple holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Invoice Simple has 123K ratings behind it against 6.7K, so its average is the more settled of the two.
