Simple Hex Calc costs $0.99 and RC Circuit Pro $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
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.
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.
