MVP App Design: Which Screens You Actually Need First

This guide is for founders and PMs about to design a first version of an app and worried about building too much or too little. MVP app design is mostly a cutting exercise: deciding which screens prove your idea and which can wait. You will get a method for finding your core loop, a screen inventory for five common app types, and a checklist to stop scope creep before it reaches a developer.

TL;DR: Design the one loop that delivers your core value — usually 5 to 10 screens — plus the minimum around it: a way in, a way to recover from errors, and a way to get help. Everything else (social features, advanced settings, gamification, dashboards) waits until users prove they want the loop. Write the screen list before you design a single pixel.

What "minimum" means in an MVP app

An MVP is the smallest product that lets real users get the core value, so you can learn whether they want it. For design, that translates to three questions:

1. •What is the one job a user hires this app for? Not three jobs. One.
2. •What is the shortest path from opening the app to that job being done?
3. •What has to exist so that path does not break? Sign-in if data must persist, error states, an empty state for first use.

Anything that does not serve one of those three is out of the MVP, no matter how good the idea is.

A useful comparison: early versions of many famous apps were narrow. Instagram launched as a photo-sharing app with filters, a feed, likes and comments — no stories, messaging or video. Uber's first version, in a single city, was about requesting a black car. Narrow is not a compromise; it is how you find out what matters.

Step 1: Write the core loop

The core loop is the repeated sequence a user goes through to get value. Write it as a sentence with arrows:

• •Habit tracker: open app → see today's habits → check one off → see streak.
• •Food delivery: browse restaurants → pick dishes → pay → track order.
• •Marketplace: search → view listing → message seller → arrange purchase.
• •Language learning: start lesson → answer questions → see progress → come back tomorrow.

Each arrow usually becomes one screen or one state. If your loop has more than six steps, it is probably two loops. Pick the one that proves the idea.

Step 2: Turn the loop into a screen inventory

List every screen and state the loop needs. Then add only the support screens without which the loop fails.

The "delete account" line is worth noting: Apple's App Store Review Guidelines require apps that support account creation to also let users start account deletion from within the app. Design it now, it is a single screen.

Step 3: Design states, not just screens

Most MVPs go wrong in the states nobody drew. For each core screen, sketch:

• •Empty: first launch, nothing yet. Tell users the next action ("Add your first habit").
• •Loading: skeletons or a spinner; avoid blank screens.
• •Populated: the happy path you would put in a pitch deck.
• •Error: what failed and what to do next, in plain language.
• •Edge: very long names, zero results, one item versus a hundred.

A five-screen MVP with all states designed is more shippable than a fifteen-screen one with only happy paths.

Step 4: Cut with a simple scoring pass

When the inventory feels long, score each screen from 1 to 3 on two questions: does the core loop break without it, and will we learn something from users using it? Keep anything scoring 3 on either. Move the rest to a "version 2" list — keeping the list visible makes it easier for the team to let go.

MVP screen inventories for five app types

Use these as a starting point and remove anything that does not fit your loop.

Habit or wellness tracker (about 7 screens)

1. •Welcome with one-line value proposition
2. •Sign up (or skip and store locally)
3. •Today view with habits and check-off
4. •Add or edit habit
5. •Habit detail with streak and history
6. •Reminder permission prompt (in context, after the first habit)
7. •Settings: reminders, account, support

Marketplace (about 9 screens)

1. •Home with search and categories
2. •Search results with basic filters
3. •Listing detail with photos, price and seller
4. •Sign in (prompted only when the user wants to act)
5. •Chat with seller
6. •Create listing (for sellers)
7. •My listings
8. •Profile with ratings
9. •Settings and support

Food ordering for one restaurant or small chain (about 8 screens)

1. •Menu with categories
2. •Item detail with options
3. •Cart
4. •Checkout: address, time, payment
5. •Order confirmation
6. •Order tracking
7. •Order history
8. •Account and support

Booking or appointments (about 7 screens)

1. •Service or provider list
2. •Provider detail
3. •Date and time picker
4. •Confirm and pay
5. •Booking confirmation with add-to-calendar
6. •My bookings (upcoming and past, with cancel)
7. •Account and notifications

B2B or SaaS companion app (about 6 screens)

1. •Sign in (often single sign-on)
2. •Home or inbox showing what needs attention
3. •Item detail
4. •Action or approval screen
5. •Notifications
6. •Settings and sign out

What to leave out (for now)

These are the features teams most often regret building first:

• •Social features like following, feeds and comments, unless social is the core value.
• •Gamification such as badges and levels. Streaks are the exception if the loop is daily.
• •Multi-step onboarding tours. One value screen and good empty states usually work better. See our onboarding screen design playbook for when longer onboarding is worth it.
• •Many sign-in options. Start with one or two. Our login screen design patterns explain which to pick, and note that Apple requires Sign in with Apple (or an equivalent privacy-focused option) when you offer certain third-party social logins.
• •Dark mode, theming and customisation. Valuable, not urgent.
• •Admin dashboards in the app. Use a spreadsheet or an off-the-shelf admin tool behind the scenes.

Fidelity: how polished should MVP screens be?

Polished enough that testers judge the idea, not the ugliness. In practice:

• •Start with low-fidelity wireframes to agree on the screen list and layout — our guide on how to wireframe an app walks through it.
• •Move to high fidelity for the core loop only, using platform defaults (system fonts, standard tab bars, native controls). Defaults look professional, are faster to build and are familiar to users.
• •Keep support screens simple and consistent.

AI tools speed up this step considerably: you can generate a first draft of the core loop in floow from a written brief, then spend your time on the states and edge cases rather than on layout from scratch.

MVP app design checklist

• •The core loop is written as one sentence with arrows.
• •Every screen in the inventory maps to the loop, entry, recovery or minimal account needs.
• •Each core screen has empty, loading, error and populated states.
• •Permissions are requested in context, not all at launch.
• •Account deletion exists if users can create accounts.
• •A "version 2" list holds everything you cut.
• •Screens use platform conventions, not a custom design system.
• •The total is roughly 5–10 screens; if it is over 15, cut again.

Once the list is stable, estimate build effort with the app cost calculator — fewer screens is the single biggest lever on cost and time.

FAQ

How many screens should an MVP app have?

Most MVP apps need between 5 and 10 core screens, plus their states. The exact number depends on your core loop. If your list goes above 15, you are probably designing more than one product.

Should an MVP have a login?

Only if users need their data saved across devices or need an identity, such as in a marketplace. Many MVPs can start with local storage or a guest mode and ask users to create an account at the moment it adds value, like saving progress.

Do I need a designer for an MVP app?

Not necessarily. Using platform defaults, a clear spacing and type system, and AI design tools, a founder or developer can produce credible MVP screens. A designer becomes more valuable once you know the core loop works and need to refine it.

What is the difference between an MVP and a prototype?

A prototype simulates the app to test ideas, often without real data or code. An MVP is a working product real users rely on. You usually prototype first, test the core loop, then build the MVP from the screens that survived.
