# FST vs Burn + Build

The clearest difference is update cadence: Burn + Build at every 9 days against FST's every 3 months. Burn + Build also leads on review sentiment (64% vs 40%) and iOS requirement (11.0 vs 16.0). FST's advantage is rating (4.1 vs 3.9). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. FST sells 2 in-app purchases, starting at $24.99 per month and Burn + Build sells 3 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

FST holds the better App Store score, 4.1 against 3.9. Both are backed by a comparable volume of ratings — 137 and 60 respectively. Written reviews complicate that: 40% of FST's written reviews are positive against 64% of Burn + Build's, so the app with the better star average is not the one people write more warmly about.

FST ships an update every 3 months, Burn + Build every 9 days. The most recent releases landed on October 9, 2026 and October 14, 2026 respectively.
