# iSymphony vs SupplyMaster

The clearest difference is review sentiment: iSymphony at 67% against SupplyMaster's 11%. SupplyMaster's advantage is rating (3.0 vs 1.0) and update cadence (every 5 weeks vs every 4 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SupplyMaster holds the better App Store score, 3.0 against 1.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 67% of iSymphony's written reviews are positive against 11% of SupplyMaster's, so the app with the better star average is not the one people write more warmly about.

iSymphony ships an update every 4 months, SupplyMaster every 5 weeks. The most recent releases landed on September 19, 2026 and October 7, 2026 respectively.
