# MacroFactor vs Flux

MacroFactor and Flux both sit at 4.8 stars, but that hides the real split: 100% of Flux's written reviews are positive against 71% of MacroFactor's. MacroFactor's advantage is ratings volume (24K vs 1) and chart position (#10 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. MacroFactor sells 10 in-app purchases, starting at $9.99 per month and Flux sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Flux holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: MacroFactor has 24K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 71% of MacroFactor's written reviews are positive against 100% of Flux's.

MacroFactor ships an update every 9 days, Flux weekly. The most recent releases landed on November 9, 2026 and October 31, 2026 respectively.
