# Cairn vs ScrivenerBridge

Both are free to download. Cairn sells 3 in-app purchases, starting at $1.99 per month and ScrivenerBridge sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Cairn ships an update every 5 days, ScrivenerBridge every 5 weeks. The most recent releases landed on October 25, 2026 and October 31, 2026 respectively.
