# Elementium vs Periodic Table PRO

Elementium and Periodic Table PRO both sit at 4.6 stars, but that hides the real split: 75% of Elementium's written reviews are positive against 50% of Periodic Table PRO's. Elementium also leads on monetization model (freemium vs paid) and ratings volume (576 vs 86). Periodic Table PRO's advantage is iOS requirement (13.0 vs 16.1). On price, rating, update cadence and ads 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 PRO sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Elementium has 576 ratings behind it against 86, so its average is the more settled of the two.
