# DP vs DP

The clearest difference is update cadence: DP at every 4 days against DP's every 2 weeks. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DP sells 2 one-off in-app purchases and DP sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

DP ships an update every 2 weeks, DP every 4 days. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
