What is App Builder?
**Menu: Club Panel → Tools & Development → App Builder**
Wallet app operators may use the same tool from App Panel (/app-builder) — the UI is nearly identical.
Prerequisites
- The club must be linked to a wallet application (Club Panel → Operations → Application & Wallet).
- The App Builder feature must be active on the club subscription.
- Your role needs view / create / update permission on the App Builder module.
- On first visit, if an app is linked, an app project is usually created automatically; otherwise contact platform admin.
Page layout
| Area | Purpose |
|---|---|
| **Left toolbar** | Tabs: Sections, Theme, Pages, Forms, Services |
| **Phone simulator (center)** | Live preview of what users see |
| **Right panel** | Edit selected section, fields, and actions |
Above the simulator: Onboarding, Login/Guest, Full preview, Refresh. An orange dot on a tab means unsaved changes.
Notes
- Output renders the same on web portal and Flutter app (some advanced widgets may look simpler on one target).
- When switching pages or tabs with unsaved changes, the system asks for confirmation.
