# Quantum Physics vs Monium

The clearest difference is price: Quantum Physics at Free against Monium's $3.99. Monium's advantage is rating (5.0 vs 4.0) and in-app purchases (none vs 1). On ratings volume and device support there is nothing between them.

Quantum Physics is free to download; Monium costs $3.99 up front. Quantum Physics sells 1 one-off in-app purchase. Monium asks for nothing beyond the download.

Monium holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively.
