# Prep vs DAA

The clearest difference is ads: DAA at none against Prep's shown. Prep's advantage is update cadence (every 5 days vs every 3 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Prep sells 10 one-off in-app purchases and DAA sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Prep ships an update every 5 days, DAA every 3 months. The most recent releases landed on November 11, 2026 and November 13, 2026 respectively.
