# Elementium vs Periodic Table

The clearest difference is ads: Elementium at none against Periodic Table's shown. Elementium also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (602 vs 54). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Elementium sells 9 in-app purchases, starting at $1.99 per month and Periodic Table sells 6 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Elementium against 4.6 for Periodic Table. That said, the two scores are not equally well evidenced: Elementium has 602 ratings behind it against 54, so its average is the more settled of the two. Written reviews split almost evenly too, at 75% and 75% positive.

Elementium ships an update every 3 weeks, Periodic Table every 3 months. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
