# Periodic Table vs Quantum Physics

The clearest difference is rating: Periodic Table at 4.8 against Quantum Physics's 4.0. Periodic Table also leads on ads (none vs shown) and ratings volume (5.4K vs 1). Quantum Physics's advantage is review sentiment (100% vs 88%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Periodic Table sells 9 in-app purchases, starting at $0.99 per month and Quantum Physics sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Periodic Table holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Periodic Table has 5.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 88% of Periodic Table's written reviews are positive against 100% of Quantum Physics's, so the app with the better star average is not the one people write more warmly about.
