# DPI vs Peekaboo

The clearest difference is ads: Peekaboo at none against DPI's shown. Peekaboo also leads on update cadence (daily vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. DPI sells 1 one-off in-app purchase and Peekaboo sells 3 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

DPI ships an update every 2 months, Peekaboo daily. The most recent releases landed on October 24, 2026 and October 6, 2026 respectively.
