In this app, you can see how action potentials work by watching the action potential as it happens and adjusting the parameters. You can add drugs such as lidocaine, tetrodotoxin, and TEA to observe the effects on the action potential. You have the option to see a single action potential with a preset current injection, or a continuous option where you can manually inject current to trigger an action potential.

The clearest difference is price: Action Potentials at Free against Human Anatomy's $2.99. Action Potentials also leads on update cadence (every 3 weeks vs every 34 months). Human Anatomy's advantage is iOS requirement (11.0 vs 13.0). On ads, in-app purchases and device support there is nothing between them.
