# ModbusV vs Crown Calc Elite

Crown Calc Elite's advantage is rating (4.8 vs 1.0) and in-app purchases (none vs 2). On update cadence, ads and device support there is nothing between them.

ModbusV is free to download; Crown Calc Elite costs $4.99 up front. ModbusV sells 2 in-app purchases, starting at $0.49 per month. Crown Calc Elite asks for nothing beyond the download.

Crown Calc Elite holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Crown Calc Elite has 118 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of ModbusV's written reviews are positive against 69% of Crown Calc Elite's, so the app with the better star average is not the one people write more warmly about.

ModbusV ships an update every 17 months, Crown Calc Elite every 22 months. The most recent releases landed on October 18, 2026 and October 22, 2026 respectively.
