# Planet Math vs STEM Quest

The clearest difference is ads: STEM Quest at none against Planet Math's shown. Planet Math's advantage is update cadence (every 2 weeks vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Planet Math sells 7 in-app purchases, starting at $2.00 per month and STEM Quest sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Planet Math ships an update every 2 weeks, STEM Quest every 2 months. The most recent releases landed on October 10, 2026 and October 15, 2026 respectively.
