iOS and Android apps, with the backend and store work included
One cross-platform codebase in Flutter or React Native, the API and admin panel it depends on, and the App Store and Google Play paperwork handled in your name.
A mobile app development company designs, builds and publishes apps for iPhone and Android, along with the server, database and admin tools the app depends on. For most business apps in 2026, the sensible default is one cross-platform codebase in Flutter or React Native rather than two separate native apps. Meritbyte Technologies is a Nepal-based web and software development company that builds cross-platform apps, runs them through App Store and Google Play review, and maintains them afterwards.
Do you need an app, or a better mobile website?
Build an app when people will use it repeatedly and need something a browser does poorly: reliable push notifications, offline use, background location, Bluetooth or NFC hardware, or a camera workflow such as scanning documents. Loyalty programs, field-staff tools, delivery tracking and booking apps for regular customers usually qualify.
If customers visit a few times a year to read and enquire, an app will sit unopened after install. A fast mobile site, or a progressive web app that can be added to the home screen, costs less and reaches everyone with a link. Our comparison of PWA vs native app covers the grey area.
Flutter, React Native or native: what should you build with?
Both cross-platform frameworks produce real installed apps, with one codebase for iOS and Android. We choose between them per project, and we will tell you when a fully native build is the better answer.
| Approach | Strengths | Best fit |
|---|---|---|
| Flutter (Dart, maintained by Google) | Draws its own UI, so screens look identical on both platforms; strong performance for animated interfaces | Branded consumer apps, apps with custom visual design |
| React Native (TypeScript, maintained by Meta) | Uses native platform components; shares language and skills with a React web app | Companies with a React website or team; apps sharing logic with web |
| Native (Swift for iOS, Kotlin for Android) | Earliest access to new platform features; deepest hardware integration | Heavy AR, watch or car integrations, advanced background audio |
Native means two codebases and roughly two build efforts. If your app needs it, we will say so plainly rather than stretch a cross-platform framework to fit.
What is included in our mobile app development
An app is rarely just the app. A typical scope includes:
- Design. User flows and a clickable prototype tested on real phones before build, following Apple's and Google's interface conventions.
- The app. iOS and Android from one codebase, with sign-in, account deletion, offline states and error handling designed, not left to chance.
- Backend. An API in Node.js with PostgreSQL, or integration with your existing systems.
- Admin panel. A web dashboard for your staff to manage users, content and orders.
- Notifications. Push through Apple Push Notification service and Firebase Cloud Messaging, with user preferences.
- Measurement. Product analytics and crash reporting from the first test build.
- Release. Store listings, screenshots, privacy disclosures and a repeatable build pipeline.
Getting through App Store and Google Play review
Store review is where many first apps stall. What we handle, in your name:
- Developer accounts. Apple's Developer Program costs US$99 a year; a Google Play developer account has a one-time US$25 fee. Organization accounts on both stores need a D-U-N-S number, which can take time to obtain, so we start early.
- Privacy disclosures. Apple's App Privacy details and Google Play's Data safety form must match what the app and every SDK inside it actually collect.
- Account deletion. Both stores require apps that let users create accounts to let them delete them too.
- Reviewer access. A demo login and notes so reviewers can reach every feature.
- Testing tracks. TestFlight for iOS and Google Play testing tracks for Android. New personal Google Play accounts must run a closed test (currently at least 12 testers for 14 days) before publishing to production.
- Payments. Digital goods sold inside an app generally have to use Apple's and Google's in-app purchase systems; exceptions differ by country and have been changing, so we check current rules for your markets.
How an app project runs
Scoping. A free conversation about users, features and systems to connect. You get a scope, timeline and number back.
First milestone at a fixed price. A clickable prototype of the main flows, the backend skeleton on a staging URL, and a first build installed on your own phone. You see the app take shape before committing to the full build.
Two-week blocks. Each block ends with a demo and a fresh test build through TestFlight and Google Play internal testing. The admin panel and API stay available on staging throughout, and a written update arrives every week. You can stop at the end of any block.
Launch. Submission, review responses, then a phased release so problems reach a small share of users first.
Run. Apple and Google ship major OS versions every year and periodically raise their minimum SDK and target API requirements. A maintenance retainer keeps the app compatible, patched and accepted by both stores.
What drives the cost of a mobile app?
Cost follows the number of screens and user roles, offline sync, real-time features such as chat or live tracking, payments, integrations with existing systems, and whether you need an admin panel (you usually do). Cross-platform saves most on screens and logic; it saves less on platform-specific features.
Budget for running costs as well: store fees, backend hosting, third-party services such as maps or SMS, and maintenance. Our mobile app development cost guide gives typical market ranges, which vary by region and provider, and the MVP development guide explains how to cut a first release down to what proves demand.
Choosing a mobile app development company
| Ask | A good answer | A worrying answer |
|---|---|---|
| Whose developer accounts will publish the app? | Yours, with us invited as team members | "Ours, we will transfer it later" |
| What does the quote include? | App, backend, admin panel, store submission | "The app" with no mention of a backend |
| How will I test during the build? | Test builds on my phone every two weeks | A demo video at the end |
| What happens after launch? | A maintenance plan for OS and policy changes | Silence, or "call us if it breaks" |
If the app is one part of a larger system, our custom software development team builds the platform behind it, and QA and testing covers device testing across screen sizes and OS versions.
Frequently asked questions
Should I choose Flutter or React Native?
Both are proven for business apps. Choose React Native if you already have a React web app or developers who know TypeScript, since skills and some code carry over. Choose Flutter if the app has a heavily customized visual design that must look identical on both platforms. Either way, the quality of the build matters more than the framework.
How long does it take to publish an app?
Build time depends on scope; the store step adds days, not months. Apple and Google reviews commonly complete within a few days, though rejections add rounds. Plan for developer account setup, D-U-N-S registration and, on a new personal Google Play account, the mandatory closed testing period, which can each add weeks if left late.
Can you take over an app another company built?
Usually. We need the source code, access to the developer accounts, backend hosting and any third-party services. We audit build health, dependencies, crash reports and store compliance, then give you a written list of what to fix first. If the accounts are in the previous developer's name, transferring them is the first job.
What maintenance does an app need after launch?
Every year, new iOS and Android versions arrive, and both stores raise minimum requirements for new builds. Apps also need dependency and security updates, crash fixes and small changes from user feedback. Without this, an app gradually breaks on new phones or gets blocked from updating. A small monthly retainer usually covers it.
Do I need separate iOS and Android apps?
Rarely. Flutter and React Native produce both from one codebase, which means one team, one set of features and releases on both platforms at once. Separate native apps make sense for apps that depend on the newest platform features or deep hardware access. For most business apps, one codebase is faster and cheaper to maintain.
