Verdict

The call

The clearest difference is rating: Invoice Simple at 4.9 against WorkApp's 4.0. Invoice Simple also leads on ratings volume (123K vs 12) and chart position (#9 vs unranked). WorkApp's advantage is review sentiment (89% vs 64%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. WorkApp sells 4 in-app purchases, starting at $8.99 per month and Invoice Simple sells 9 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Invoice Simple holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Invoice Simple has 123K ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 89% of WorkApp's written reviews are positive against 64% of Invoice Simple's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

WorkApp ships an update fortnightly, Invoice Simple every 2 weeks. The most recent releases landed on October 22, 2026 and November 3, 2026 respectively.
