Start here
From installed app to shopper-ready experience
Work through these four checkpoints in order. You can return to the builder and refine the experience before publishing again.
2
Shape the design
Use Builder to arrange pages, navigation, colors, type, imagery, and the shopping features you want customers to use.
3
Preview and save
Check the mobile preview, open products and menus, then save your draft when the experience looks and behaves correctly.
4
Publish deliberately
Start with the web app for fast device testing. Prepare Android or iOS only when your own platform accounts are ready.
Design & preview
Make every visible feature earn its place
A polished app is more than brand colors. Check what shoppers can find, tap, understand, and complete from each screen.
Brand and layout
Set your logo, colors, typography, banners, and content sections in Builder. Keep important products and actions near the top, and review generated text before saving it.
Pages and navigation
Confirm every enabled destination has a clear path in your bottom navigation, menus, home sections, or product flow. Remove links to anything you are not ready to offer.
Mobile preview
Open menus, search, a product, the cart, account areas, and checkout handoff. Test long titles and real catalog images, then save the draft you intend to publish.
Changes are not appearing?
First confirm the latest draft was saved. If you are checking an already published web app, return to Publish and regenerate it, then reopen the live link. A browser refresh may also be needed after a new release.
Local shopping
Bring nearby sellers into your branded app
For stores with a configured VendorIQ marketplace and access to the local-commerce connection, AppBuilder can show nearby vendors, menus, delivery or pickup choices, and a signed-in shopper's own order progress. AppBuilder's Orders view reads Shopify Customer Account for that signed-in customer. VendorIQ-connected tracking and reorder details need a separately verified link to the specific purchase and store. VendorIQ's merchant-reviewed missing-order screen belongs to its separate native shopper app; it is not an AppBuilder recovery control. The connection is limited availability; check its status before designing around it.
Start from your marketplace
Open Features → Local delivery & pickup to begin a local-shopping draft, then review it in App Builder. Use Integrations → VendorIQ connection to check whether the store and connection are ready. A draft is yours to review before you publish.
Choose what shoppers see
Place and tune the vendor directory, delivery availability, product serviceability, menu choices, slot picker, order timeline, live tracking, and reorder sections. Set the logo, colors, type size, button shape, card spacing, and light or dark look, then preview common shopping and unavailable states before publishing. Builder's samples show the design; test live checkout and order progress in a connected shopper build.
Keep promises current
VendorIQ remains the source for service areas, prices, pickup points, slot capacity, menus, and order status. Set those operating rules in VendorIQ; AppBuilder controls how they appear in your app. DeliveryIQ is a separate delivery app and does not currently supply this branded-app flow.
Need to set up local delivery first?
Follow the VendorIQ guide for zones, pickup, food menus, and vendor operations. AppBuilder's local-shopping screens use those settings rather than keeping a second copy.
Publishing & installation
Choose the release path that fits your store today
The installable web app and native store apps are separate destinations. Publishing one does not automatically publish the others.
Progressive web app
In AppBuilder, open Publish, choose the web app, complete the readiness checks, and generate or regenerate it. Open the live link on the device you want to test.
On Android, use the browser menu and choose Install app or Add to Home screen. On iPhone or iPad, open the link in Safari, use Share, then choose Add to Home Screen. Wording can vary by browser and device.
Android and iOS
Native apps require merchant-owned Google Play or Apple developer accounts and the release credentials requested inside AppBuilder. Keep those accounts, agreements, fees, and credentials current.
AppBuilder can help prepare configured native builds and run readiness checks. You remain responsible for reviewing the store listing and release, and Apple and Google independently decide approval and timing.
A safe way to test
Publish the web app first and test it on a real phone. For native work, use a preview build before preparing a merchant-signed store release. A preview does not prove push delivery or guarantee store approval.
Billing & plans
Plan changes stay inside Shopify
Use the Billing page in AppBuilder to compare available plans, included features, and usage limits before making a change.
Upgrade
Select an available paid plan from Billing. Shopify shows the charge for your approval before the paid subscription begins.
Review usage
Check the plan and usage bars shown in the app before using metered features such as AI actions or builds. Limits reset or apply as described on the Billing page.
Cancel
Manage your subscription through Shopify Admin. Uninstalling the app cancels its subscription under the terms shown for the service.
Need help with a charge or plan?
Do not approve a charge you do not recognize. Email the store's
.myshopify.com domain and the plan or charge shown on screen—never send a password or access token.
Privacy & deletion
Clear routes for merchants and shoppers
Use the route that matches whose data is involved. The Privacy Policy contains the complete retention and deletion details.
Merchant store data
After uninstall, store data is deleted within 30 days as described in the Privacy Policy. An authorized merchant can request earlier deletion by emailing support and including the store's .myshopify.com domain.
Shopper account data
An authenticated shopper can request deletion from the generated app. The shopper may also contact the merchant or Kernvel support. AppBuilder requests erasure through Shopify and removes its related shopper data when Shopify accepts the request.
Protect sensitive credentials
Never email passwords, access tokens, private keys, signing files, or app-store credentials. Enter credentials only in the protected fields provided inside AppBuilder.
