# Planet Math vs One More Thing

The clearest difference is in-app purchases: One More Thing at none against Planet Math's 7. One More Thing also leads on ads (none vs shown) and update cadence (every 2 days vs every 2 weeks). Planet Math's advantage is ratings volume (13 vs 1). On price, 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. One More Thing asks for nothing beyond the download.

One More Thing holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Planet Math has 13 ratings behind it against 1, so its average is the more settled of the two.

Planet Math ships an update every 2 weeks, One More Thing every 2 days. The most recent releases landed on November 3, 2026 and November 6, 2026 respectively.
