Verdict

The call

The clearest difference is in-app purchases: Numerical³ at none against iWorkBoard's 1. Numerical³ also leads on ads (none vs shown) and ratings volume (1.3K vs 2). iWorkBoard's advantage is rating (5.0 vs 4.8) and iOS requirement (15.6 vs 18.0). On price, review sentiment and update cadence there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iWorkBoard holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Numerical³ has 1.3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Numerical³'s written reviews are positive against 70% of iWorkBoard's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on October 26, 2026 and September 30, 2026 respectively.
