Should I build native or cross-platform?

Cross-platform (React Native or Flutter) is the right choice for 80% of apps. Go native only if you need heavy GPU work, AR, or very platform-specific interactions.

How much does a mobile app cost?

A cross-platform MVP with Bookuvai runs $500-$900. Traditional agencies charge $50k-$150k. The scope and quality are comparable; the delivery model is different.

How long does app store review take?

Apple review typically takes 1-3 days. Google Play is faster, often within hours. First submissions take longer. Budget a week for potential rejections and resubmissions.

How to Build a Mobile App Users Actually Love

Navigate the key decisions from native vs. cross-platform to app store submission with this practical mobile development guide.

Project type: Mobile Application

Building a mobile app involves choosing the right framework, designing for small screens, building reliable backend APIs, and navigating app store review processes. This guide covers the fastest path to a shipped mobile product.

Prerequisites

Target platforms decided (iOS, Android, or both)
Core feature set defined with user stories
Apple Developer and/or Google Play accounts created

Steps

Choose Native or Cross-Platform: This is the biggest architectural decision. Cross-platform saves time; native gives maximum performance and platform-specific UX.
- React Native / Flutter vs. Swift / Kotlin native
- Shared codebase vs. separate iOS and Android teams
Design Mobile-First UI and Navigation: Design for thumb zones, small screens, and intermittent connectivity. Use platform-native navigation patterns users already understand.
- Tab bar vs. drawer navigation pattern
- Custom design system vs. platform-native components
Build Backend APIs and Data Sync: Create RESTful or GraphQL APIs for your mobile client. Implement offline support and data syncing for unreliable network conditions.
- REST vs. GraphQL for the API layer
- Offline-first with local storage vs. online-only
Test, Submit, and Iterate: Run beta tests via TestFlight and Google Play Internal Testing. Prepare store assets, handle review feedback, and set up OTA updates.
- Over-the-air updates (CodePush) vs. full store releases only
- Phased rollout vs. full release on launch day

Estimated Scope

Hours: 250 - 450 | Cost: $500 - $900 | Timeline: 8 - 14 weeks

Common Mistakes

Building for both platforms from day one: Launch on one platform first to validate, then expand; or use cross-platform from the start
Ignoring offline scenarios: Mobile users frequently lose connectivity; cache critical data locally and sync gracefully
Skipping app store guideline review: Read Apple and Google guidelines before building; rejection after weeks of work is costly
