# Doroosi vs Periodic Table

The clearest difference is update cadence: Periodic Table at every 11 days against Doroosi's every 17 months. On price, ads, in-app purchases and device support there is nothing between them.

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

Doroosi ships an update every 17 months, Periodic Table every 11 days. The most recent releases landed on September 27, 2026 and October 1, 2026 respectively.
