Make an app with login, sign-up and a dashboard (no code)

Almost every app that outgrows a single phone needs the same first four screens: sign up, log in, a home dashboard that shows the user something useful the moment they land, and a profile page to change their name or password. A gym in Lagos wants members to see their remaining sessions; a coaching centre in Jaipur wants students to see attendance and fees; a small SaaS founder wants a working prototype with real accounts before hiring anyone. The screens are boring, the mistakes are expensive, and they are the part most people get stuck on.

Describing this app to App Builder Agent beats a template because templates give you a login form with nothing behind it. When you describe the app, the AI agent writes a real React Native app, deploys a hosted backend for accounts and data, wires the two together, and you test the whole thing in a live phone preview in the browser. This guide walks through what to ask for, the prompt that produces a clean first build, and the mistakes that make login apps feel untrustworthy.

What a login and dashboard app must handle

• Sign-up with validation — email format, password strength, and a clear error when the email is already taken.
• Login that survives restarts — the session token is saved on the device so users stay signed in until they log out.
• OTP or email verification — a six-digit code with expiry and a resend timer, so an unverified account cannot reach the dashboard.
• Roles — at least admin and member; the admin sees everyone, the member sees only their own data.
• Home dashboard with stats — three or four tiles that answer "how am I doing" plus a short recent-activity list.
• Profile screen — edit name and phone, change password, upload an avatar, log out, delete account.
• Forgot password — a reset flow, or people will email you every week.
• A hosted backend — accounts are shared data; they cannot live only in one phone's storage.

Build it with App Builder Agent, step by step

The key phrase for this app is "hosted backend". Say it in the first message and the agent creates a live API for accounts and dashboard data instead of a local-only mock.

1. Start a mobile app project. Open the builder, choose a mobile app, and pick a working title. You can rename it and set the icon later.
2. Describe the accounts, roles and dashboard in one message. Name the roles, list the tiles, and choose the login method. This prompt is a good starting shape:
   Build a membership app for "IronPeak Gym" in Lagos. Sign-up with name, email, phone and password; login by email and password, and stay logged in. Verify new accounts with a 6-digit OTP sent by email, 10-minute expiry, resend after 30 seconds. Roles: admin and member. Member home dashboard shows four tiles: sessions left this month, next class, total visits, membership expiry date, then a recent check-ins list. Admin dashboard shows members count, active today, expiring this week, revenue this month in NGN, and a searchable member table with a Promote to admin button. Profile screen: edit name/phone, change password, avatar, log out. Hosted backend. Deep green and off-white design.
3. Test the whole loop in the preview. Sign up, enter the OTP the preview shows you, land on the dashboard, close and reopen the app to confirm you are still logged in, then log out. Try signing up twice with the same email and check the error message reads like a sentence.
4. Add the forgotten-password flow and seed data. Empty dashboards look broken, so ask for realistic sample members while you test.
   Add a Forgot password link: ask for the email, send a 6-digit reset code, then a new-password screen. Also seed 25 sample members with Nigerian names, random join dates in the last 8 months and visit counts, so the admin table and the member tiles show real numbers.
5. Ship it. Download the release-signed test APK from the Preview tab for your first members, then make a signed APK and AAB with your own package id when you are ready for the Play Store.

Prompts that work well

The same skeleton — accounts, roles, tiles, profile — fits very different businesses. Swap the nouns and the numbers:

Common mistakes (and the fix)

• Forgetting to ask for a hosted backend. The agent then stores the "account" on the phone, which means a second phone knows nothing about it. Fix: say "hosted backend" in the first message, or ask the agent to move accounts to a hosted backend now.
• OTP with no expiry or resend rule. Users tap resend ten times and every code is valid forever. Fix: state the expiry and the resend delay in the prompt, and ask that the newest code invalidates the older ones.
• One dashboard for every role. Members see admin numbers, or admins see a tile that says "sessions left". Fix: describe each role's dashboard separately and ask the agent to guard admin screens on the backend, not only in the menu.
• Silent login errors. A wrong password shows nothing, or shows the raw server text. Fix: ask for plain-English messages: "That password is wrong" and "No account with that email".
• No logged-out state on restart. The app opens on the dashboard even after log-out because the token was never cleared. Fix: test log out then reopen in the preview and report it to the agent.
• Empty dashboards during testing. You cannot judge the layout with zeros. Fix: ask for seed data, then ask the agent to remove it before the release build.

Make it feel finished

• Add a short onboarding of two or three slides before sign-up that explains what the app does, with a Skip button.
• Show skeleton placeholders on dashboard tiles while data loads instead of a spinner over a blank screen.
• Greet the user by first name on the dashboard, and show the date and a small avatar top-right that opens the profile.
• Make pull-to-refresh work on the dashboard; people expect it.
• Ask for an offline banner that says "You're offline, showing the last update" instead of a failed request.

Installing, publishing and next steps

When sign-up, OTP, dashboard and profile all work in the preview, download the release-signed test APK from the Preview tab and put it on two phones: sign up on one, log in on the other, and confirm the same account and stats appear. That is the real test of the hosted backend. For a store listing, the AI app builder makes a signed APK and AAB with your own package id and version, and the keystore stays with the project so updates keep working.

If you want to see finished examples of this pattern first, browse the ready-made login & dashboard apps in the gallery. Once accounts are in place, the natural next steps are a management view for the owner — see building an admin dashboard app for your business — or adding a chat between your users, covered in building a chat and messaging app without coding. Open the builder, paste the prompt above with your own business name, and you will have a working login in a few minutes.
