Mobile app development

We build iOS and Android apps with React Native and Flutter, plus the APIs, admin panels and release pipelines behind them.

Overview

A mobile app is really three products: the app, the back end that feeds it and the admin panel your team uses to run it. We build all three together, so they ship together. Most clients start cross-platform with React Native or Flutter, which keeps one codebase for iOS and Android. When a feature needs the camera, Bluetooth or background location at a lower level, we write native modules in Swift or Kotlin. We handle store submission, crash reporting and over-the-air updates, and plan releases around your markets.

01 — What we deliver

  • 01

    Cross-platform apps

    React Native or Flutter apps with a single codebase and platform-specific polish on iOS and Android.

  • 02

    Native modules

    Swift and Kotlin for hardware access, background tasks and performance-critical screens.

  • 03

    App back ends and APIs

    Authentication, push notifications, payments, file storage and real-time data, designed alongside the app.

  • 04

    Admin panels

    Web dashboards for managing users, content, bookings, orders and reports without touching the database.

  • 05

    Store release and compliance

    App Store and Google Play submission, privacy labels, data safety forms and fixes for review rejections.

  • 06

    App takeovers

    Taking over stalled apps: fixing crashes, upgrading dependencies and restoring a steady release rhythm.

02 — Solutions

Booking and membership apps

Classes, rooms and appointments with payments, reminders and member profiles.

Field and operations apps

Offline-first data capture with photos, GPS and forms that sync when the connection returns.

Marketplace apps

Two-sided apps for buyers and sellers with listings, chat, ratings and payouts.

Fintech and wallet apps

KYC onboarding, UPI and card payments, transaction history and secure on-device storage.

Companion apps for devices

Bluetooth pairing, sensor readings and dashboards for IoT hardware in the field.

03 — Delivery cycle

  1. Step 01

    Product discovery

    We define users, core journeys and the smallest first release worth putting in the stores.

  2. Step 02

    UX and prototyping

    Clickable Figma prototypes, tested on real phones before any code is written.

  3. Step 03

    Architecture

    We choose cross-platform or native per feature and fix the API contracts between app and back end.

  4. Step 04

    Sprints

    Two-week sprints with TestFlight and Google Play internal builds you can install and review.

  5. Step 05

    Device QA

    Testing on low-end Android phones and recent iPhones, with throttled networks and interrupted sessions.

  6. Step 06

    Store submission

    Listings, screenshots, privacy policies and review responses handled under your developer accounts.

  7. Step 07

    Launch and monitoring

    Staged rollout, crash reporting and analytics, with a fix-forward plan for the first weeks.

06 — Why Foxbeta

  • 01

    Honest platform advice

    We tell you when cross-platform is enough and when a native build will save you pain later.

  • 02

    Tested on the phones your users carry

    Budget Android devices common in India and the Gulf get the same attention as the latest iPhone.

  • 03

    One team for app, API and admin

    No hand-off gaps between a mobile agency and a back-end vendor. One team owns the whole product.

  • 04

    Releases you control

    Automated builds, staged rollouts and over-the-air updates through Expo for fast, low-risk fixes.

08 — FAQ

Should we choose React Native or Flutter?
Both are mature. React Native suits teams already using React and TypeScript on the web, and shares logic with web apps. Flutter suits highly custom, pixel-consistent interfaces. We recommend one after discovery based on your team, features and roadmap.
How long does it take to build an app?
A focused first version typically takes 10–16 weeks, including the back end and admin panel. Apps with several user roles, offline sync or hardware integration take longer. We give a firm timeline after discovery.
How much does app development cost?
Cost depends on the number of screens and user roles, back-end complexity, integrations such as payments or maps, offline requirements and whether any native modules are needed. We give a fixed quote after a short discovery call.
Will you publish the app to the App Store and Google Play?
Yes. We prepare listings and handle submission and review under your own developer accounts, so the app and its reviews always belong to you.
Can you take over an app another team built?
Yes. We start with a code and infrastructure audit, then give you a written plan covering stability fixes, upgrades and what to keep or rewrite.
Who owns the source code?
You do. Code sits in your repository from the first commit, and full intellectual property transfers to you under the contract.
