# SixtyForty vs CellMaster

The clearest difference is rating: CellMaster at 5.0 against SixtyForty's 3.7. SixtyForty's advantage is review sentiment (100% vs 58%) and iOS requirement (16.0 vs 18.0). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. SixtyForty sells 1 one-off in-app purchase and CellMaster sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CellMaster holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 100% of SixtyForty's written reviews are positive against 58% of CellMaster's, so the app with the better star average is not the one people write more warmly about.

SixtyForty ships an update every 2 weeks, CellMaster every 3 weeks. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
