Verdict

The call

The clearest difference is review sentiment: Professional Invoicing at 95% against 1Ci's 0%. Professional Invoicing also leads on update cadence (every 3 weeks vs every 17 months) and ratings volume (118 vs 5). 1Ci's advantage is rating (5.0 vs 4.7) and iOS requirement (9.0 vs 11.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

1Ci holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Professional Invoicing has 118 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 95% of Professional Invoicing's written reviews are positive against 0% of 1Ci's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Professional Invoicing ships an update every 3 weeks, 1Ci every 17 months. The most recent releases landed on October 15, 2026 and October 6, 2026 respectively.
