# SQLDOU vs DP

The clearest difference is ads: DP at none against SQLDOU's shown. DP also leads on update cadence (every 5 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

SQLDOU ships an update every 3 weeks, DP every 5 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
