# ArchCam vs Plumb

The clearest difference is update cadence: Plumb at every 4 days against ArchCam's every 8 days. ArchCam's advantage is ratings volume (5 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. ArchCam sells 1 one-off in-app purchase and Plumb sells 3 in-app purchases, starting at $1.99 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 ArchCam against 5.0 for Plumb. That said, the two scores are not equally well evidenced: ArchCam has 5 ratings behind it against 1, so its average is the more settled of the two.

ArchCam ships an update every 8 days, Plumb every 4 days. Both last shipped on November 10, 2026.
