12 Features a Startup MVP App Needs, and What to Leave Out

A mobile MVP needs one complete core flow, sign-in only if the value requires it, in-app account deletion if you have accounts, onboarding that reaches the first moment of value, analytics on that moment, crash reporting, a feedback channel, a simple admin view, payments only if you are testing willingness to pay, accurate store privacy disclosures, a way to force updates and a privacy policy. Leave out anything that does not help you learn whether people want the core flow.

This list is for founders scoping a first app. It is the mobile counterpart to our SaaS MVP feature-prioritisation guide, which covers how to decide what goes in. Here we focus on what app stores and real-world use add to that list. Store requirements were checked against Apple and Google documentation on 28 October 2026.

The MVP exists to test one thing: whether people will do the core action and come back. Build that flow end to end, polished enough that a failure means the idea is weak, not that the app is broken. A fitness app's core flow might be choosing and completing a workout; a services marketplace's might be requesting and receiving a quote.

If people can get value without an account, let them, and ask for one when they want to save progress. When you do need accounts, offer the quickest options your users expect, such as email links, phone numbers, Sign in with Apple and Google sign-in. Apple's App Review Guidelines (4.8) require apps that use a third-party login to also offer an equivalent login option that limits data collection, and Sign in with Apple meets that. Passkeys reduce password resets; see passkeys implementation.

This is a store requirement, not a nice-to-have. Apple says apps that support account creation must let people start deleting their account within the app, and that only offering to deactivate it is not enough. Google Play requires an in-app path to delete the account and its data, plus a web link where people can request deletion without reinstalling the app. Build it into the MVP; retrofitting it after a rejection costs more.

Every screen between install and the core action loses people. Ask for permissions when the feature needs them, not on first launch, and skip the feature tour. Our mobile onboarding guide lists patterns that work.

Without analytics, an MVP cannot answer its own question. Track a small set of events: install or first open, sign-up, the activation event (the core action completed), and return visits. Name them consistently from the start. See which mobile app events and metrics to track.

Early users rarely report crashes; they delete the app. A crash-reporting SDK tells you which devices and app versions fail and where. Set it up before the first beta. See mobile app crash reporting.

A feedback link, an in-app support email or a chat button. Early users who bother to write are your best source of learning, and a response from a founder builds loyalty. Keep it simple; a full help centre can wait.

Someone has to look up users, fix data, moderate content or refund a payment. A simple internal admin screen, or a well-configured backend console, saves hours of database queries and mistakes. See admin panel build vs buy.

If the MVP's question includes "will people pay?", build the payment flow. Digital features and subscriptions used in the app normally go through Apple's in-app purchase and Google Play Billing; physical goods and real-world services use your own payment provider. Our mobile app monetisation guide maps each model to the store rules. If price is not the question yet, leave payments out.

Both stores ask you to declare what data the app and its SDKs collect: Apple's App Privacy details and Google Play's Data safety section. Analytics, crash reporting and ad SDKs all count. Both stores also expect a privacy policy link. Inaccurate disclosures can lead to rejection or removal, so list SDKs as you add them. See mobile app data privacy.

Once an app is on someone's phone, you cannot change it instantly. A minimum-version check lets you block a broken or insecure version, and remote configuration lets you switch a feature off or change a message without a release. Both are cheap to add at the start and hard to add later.

Plan for beta testing before launch: TestFlight on iOS and testing tracks on Google Play. Google Play requires personal developer accounts created after 13 November 2023 to run a closed test with at least 12 testers for 14 days before applying for production access. Build that time into the launch plan; see how long it takes to build a mobile app.

These are often requested and rarely help an MVP answer its question:

A mobile MVP is small in features but not in basics. Build one complete core flow, the store requirements (account deletion, privacy disclosures) and the instruments that tell you whether it works (analytics, crash reporting, feedback). Everything else can wait for evidence. For budget ranges and what drives them, see mobile app development cost.
