# Physics Questions vs ChemVista

The clearest difference is in-app purchases: ChemVista at none against Physics Questions's 9. ChemVista also leads on ads (none vs shown). Physics Questions's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price there is nothing between them.

Both are free to download. Physics Questions sells 9 one-off in-app purchases. ChemVista asks for nothing beyond the download.
