Both are free to download. KNECT Pro sells 3 in-app purchases, starting at $89.99 per year. SupplyMaster asks for nothing beyond the download.
SupplyMaster holds the better App Store score, 3.0 against 1.0. Both are backed by a comparable volume of ratings — 2 and 4 respectively. Written reviews complicate that: 11% of SupplyMaster's written reviews are positive against 28% of KNECT Pro's, so the app with the better star average is not the one people write more warmly about.
SupplyMaster ships an update every 5 weeks, KNECT Pro weekly. The most recent releases landed on June 9, 2026 and September 21, 2026 respectively.
