# ModbusV vs UNI

The clearest difference is review sentiment: ModbusV at 100% against UNI's 25%. UNI's advantage is rating (3.0 vs 1.0) and in-app purchases (none vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. ModbusV sells 2 in-app purchases, starting at $0.49 per month. UNI asks for nothing beyond the download.

UNI holds the better App Store score, 3.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 3 respectively. Written reviews complicate that: 100% of ModbusV's written reviews are positive against 25% of UNI'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, UNI every 6 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
