Paste your site in the builder
Build a demo APK first to try it on your phone; Builder Pro builds the full app and the AAB.
The pages people actually use
Most visitors to a business site want three things: what you offer, how to book or order, and how to reach you. Put those in bottom tabs. A booking widget (Calendly, a salon system, a table booking form) works in the app as it does in the browser.
Push notifications
Schools send closures and event reminders; restaurants send offers; gyms send class changes. With OneSignal set up in the builder, you send them from OneSignal's dashboard. See the push guide.
Sharing without Google Play
For staff or a school community you can share the APK directly — no Play listing needed. For the public, publish the AAB on Google Play.
