# OffBlock vs Crew Prime

OffBlock and Crew Prime are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. OffBlock sells 4 in-app purchases, starting at $2.99 per month and Crew Prime sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

OffBlock ships an update every 2 months, Crew Prime every 3 months. Both last shipped on October 24, 2026.
