# BuildSheet vs ModMap

The clearest difference is update cadence: ModMap at daily against BuildSheet's every 9 days. ModMap also leads on review sentiment (100% vs 75%). BuildSheet's advantage is ratings volume (46 vs 5) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. BuildSheet sells 2 in-app purchases, starting at $4.99 per month and ModMap sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for BuildSheet against 5.0 for ModMap. That said, the two scores are not equally well evidenced: BuildSheet has 46 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 75% of BuildSheet's written reviews are positive against 100% of ModMap's.

BuildSheet ships an update every 9 days, ModMap daily. The most recent releases landed on October 18, 2026 and October 2, 2026 respectively.
