OpenSprinkler holds the better App Store score, 3.9 against 2.5. That said, the two scores are not equally well evidenced: OpenSprinkler has 29 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 65% of OpenSprinkler's written reviews are positive against 67% of Average Calculator Professiona's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 24, 2026 and September 5, 2026 respectively.
