# Sunja vs Quantum Physics

The clearest difference is iOS requirement: Sunja at 17.6 against Quantum Physics's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Sunja sells 2 in-app purchases, starting at $29.99 per month and Quantum Physics sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
