Verdict

The call

The clearest difference is price: Canopy Client Portal at Free against Adding Machine 10Key iPhone's $2.99. Canopy Client Portal also leads on ratings volume (24K vs 131) and update cadence (weekly vs every 5 weeks). Adding Machine 10Key iPhone's advantage is chart position (#127 vs unranked) and iOS requirement (12.4 vs 17.0). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Canopy Client Portal holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Canopy Client Portal has 24K ratings behind it against 131, so its average is the more settled of the two. Written reviews complicate that: 95% of Adding Machine 10Key iPhone's written reviews are positive against 93% of Canopy Client Portal's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Adding Machine 10Key iPhone ships an update every 5 weeks, Canopy Client Portal weekly. Both last shipped on October 14, 2026.
