# Elementium vs Periodic Table

The clearest difference is in-app purchases: Periodic Table at none against Elementium's 9. Periodic Table also leads on rating (5.0 vs 4.6) and iOS requirement (13.4 vs 16.1). Elementium's advantage is ratings volume (576 vs 1). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Elementium sells 9 in-app purchases, starting at $1.99 per month. Periodic Table asks for nothing beyond the download.

Periodic Table holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Elementium has 576 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 19, 2026 and June 4, 2026 respectively.
