An App is a packaged outcome rather than a tool. It has a card, a looping preview, one or
two inputs, and a price you can see before you run it. No settings are shown at all.
### App vs preset vs Flow
- A preset is a bundle of settings inside a tool you already opened.
- A Flow is your own saved chain of steps.
- An App is somebody else's Flow, wrapped in a card with a promise on it.
Open Advanced on any App to see the Flow underneath and edit a copy.
### Free Apps
A rotating set is free, and their output is watermarked — that is the trade. Running the same App
on credits removes the mark. The Free plan watermarks everything regardless of the App.
### Cost
Every card shows its price before you run it. Free Apps show zero.
