Verdict

The call

The clearest difference is review sentiment: Shopbook at 100% against Invoice Maker ▸ Invoice Simple's 64%. Invoice Maker ▸ Invoice Simple's advantage is update cadence (every 11 days vs every 3 months) and ratings volume (123K vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Invoice Maker ▸ Invoice Simple sells 9 in-app purchases, starting at $6.99 per month and Shopbook sells 3 in-app purchases, starting at $6.00 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Invoice Maker ▸ Invoice Simple holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Invoice Maker ▸ Invoice Simple has 123K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 64% of Invoice Maker ▸ Invoice Simple's written reviews are positive against 100% of Shopbook's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Invoice Maker ▸ Invoice Simple ships an update every 11 days, Shopbook every 3 months. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
