Verdict
The clearest difference is ads: PockeTech at none against Invoice Maker's shown. PockeTech also leads on update cadence (every 8 days vs monthly). Invoice Maker's advantage is ratings volume (5 vs 1) and iOS requirement (15.0 vs 17.6). On price, rating, 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
Both are free to download. PockeTech sells 2 in-app purchases, starting at $9.99 per month and Invoice Maker sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for PockeTech against 5.0 for Invoice Maker. That said, the two scores are not equally well evidenced: Invoice Maker has 5 ratings behind it against 1, so its average is the more settled of the two.
PockeTech ships an update every 8 days, Invoice Maker monthly. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
