ReceptionRating · Positive reviews · Number of ratings

Simple Hex Calc holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Simple Hex Calc has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 94% of Simple Hex Calc's written reviews are positive against 100% of RC Circuit Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Simple Hex Calc ships an update every 5 months, RC Circuit Pro every 4 months. The most recent releases landed on October 15, 2026 and October 10, 2026 respectively.
