# Physics Master vs Photronium

The clearest difference is review sentiment: Photronium at 100% against Physics Master's 50%. Photronium also leads on rating (5.0 vs 2.0) and ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Physics Master sells 11 in-app purchases, starting at $0.99 per month and Photronium sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
