Should we build mobile or web first?

For most SaaS products, web first. Your web app is easier to iterate on (no App Store review delays), easier for users to access (no download required), and provides the backend infrastructure your mobile app will consume. The exception is products with a fundamentally mobile use case — location-based features, camera-dependent workflows, or on-the-go consumption patterns. We can help you evaluate which order makes sense for your specific product during the scoping call.

How do over-the-air updates work without going through the App Store?

React Native apps consist of a native shell and a JavaScript bundle. Over-the-air update services like CodePush let you push updated JavaScript bundles directly to users' devices without submitting a new binary to the App Store. This works for UI changes, bug fixes, and logic updates — anything that does not require new native code. Apple and Google allow this as long as the updates do not change the app's primary purpose. In practice, 80% of your post-launch changes can ship via OTA within hours.

What happens if the mobile MVP validates and we want to invest more?

The MVP codebase is designed for extension. Feature flags and clean component architecture mean adding new screens, workflows, and integrations follows established patterns. Most clients continue in two-week sprint cycles, prioritising features based on the usage data the MVP collects. If you eventually need native-specific features (ARKit, complex animations), we can add native modules to the React Native project without rewriting from scratch. The MVP is a starting point, not a throwaway.

Cross-Platform Mobile MVP: Ship to iOS and Android Simultaneously

Building separate native apps for iOS and Android doubles your development cost, doubles your maintenance burden, and — most importantly for a startup — doubles the time before you get your product in front of users. React Native eliminates this trade-off. We build a single codebase that ships to both platforms simultaneously, with native performance and platform-appropriate interactions, in a fraction of the time and cost of two native builds. For startups validating mobile product-market fit, this means you can test your hypothesis on both platforms at once and iterate based on real user feedback rather than guessing which platform to prioritise.

Built for Iteration, Not Perfection

Your mobile MVP is not your final product. It is a learning tool that happens to also be a product. Every architectural decision we make optimises for your ability to change direction based on what users tell you.

Feature Flags from Day One: We ship with feature flags so you can enable experimental features for specific user segments, run A/B tests on different workflows, and roll back changes without deploying a new app version. This lets you iterate at the speed of a web app even though you are in an app store.
Over-the-Air Updates: Using CodePush or Expo Updates, we configure your app to receive JavaScript bundle updates without going through the App Store review process. Bug fixes, copy changes, and minor feature additions reach your users within hours, not the five to seven day review cycle that kills startup momentum.
Analytics-Driven Screens: Every screen is instrumented with event tracking that answers product questions: where do users spend time? Where do they abandon flows? Which features correlate with retention? Your product decisions after launch are based on data, not intuition.
Feedback Mechanism Built In: We include an in-app feedback button that captures user comments along with a screenshot, device info, and session context. Early users are your most valuable source of product insight — we make it effortless for them to share it.

What Ships to Both App Stores

A complete, polished mobile application that users can download, use, and provide feedback on.

Who This Is For

Startups that need to validate whether mobile is a viable channel before committing to a full mobile engineering team. Founders whose users are asking for a mobile experience and who want to test the market with a real product rather than a landing page survey. Product teams evaluating whether to invest in mobile by shipping a focused MVP and measuring real engagement metrics against their web product's benchmarks.

Why SaaS Development Agency for Mobile MVPs

We have shipped React Native MVPs to both app stores for dozens of startups. We know which features matter for validating mobile product-market fit (push notifications, smooth core workflow, fast load times) and which ones are premature (complex offline sync, advanced animations, multi-language support). We will push back on features that delay your launch without contributing to the learning you need to make your next product decision. Our goal is to get your app into real users' hands as quickly as possible so you can make informed decisions about your mobile investment based on actual usage data.

Frequently Asked Questions

A focused mobile MVP — core workflow, authentication, push notifications, and App Store submission — typically takes six to ten weeks from kickoff to live in both app stores. The timeline depends on the complexity of your core workflow and whether you have an existing API or we need to build one. If your product already has an API-first architecture, the mobile build is significantly faster because we are building a client, not extracting a backend.
