Mobile App Development Services for iOS and Android
CasperB2B's mobile app development services take a business from idea to a live iOS and Android app: discovery, UX design, build, testing, App Store and Google Play launch, and ongoing support. It is for owners and teams who need an app customers or staff will actually use, built from a signed scope with one accountable team.
If what you need runs in a browser, such as an internal dashboard, portal or quoting tool, start with custom business app development instead.
What you get
A written scope
Screens, features, user roles and integrations listed in plain language before any code is written, so you know what is being built.
Clickable UX design
Wireframes and a tappable prototype you can test on your own phone and change before the build starts.
iOS and Android builds
Native or cross-platform code, based on what your app needs. You own the code and the store accounts.
Testing on real devices
Functional, regression and device checks across screen sizes and OS versions, backed by our software testing and QA services.
Store launch
App Store and Google Play listings, screenshots, privacy details and review submission, handled with you.
Support after launch
Fixes, OS updates and small changes through application maintenance and support.
How it works
- Discovery. We learn who uses the app, what job it does, and what it must connect to, such as your CRM, payments or an existing database.
- UX and prototype. We design the main flows and hand you a prototype to tap through. Changes here are cheap.
- Build in short cycles. We ship working builds you can install on your phone every cycle, so you see progress instead of hearing about it.
- Test. We test each build on real devices and fix what we find before it reaches users.
- Launch. We prepare the store listings, submit for review, and handle any reviewer feedback.
- Support. We monitor crash reports, keep the app current with new iOS and Android releases, and plan the next round of features.
Native vs cross-platform, in plain terms
| Approach | What it means | Good fit when |
|---|---|---|
| Native | Separate apps written for iOS and Android with each platform's own tools. | The app leans hard on the camera, sensors, background tasks or heavy graphics, or must feel exactly like the platform. |
| Cross-platform | One shared codebase that produces both an iOS and an Android app. | Most business apps: forms, accounts, lists, bookings, messaging and dashboards. One codebase is usually faster to build and simpler to maintain. |
We recommend one in the scope and explain why. If a cross-platform app would do the job, we will say so.
What we need from you
- One decision-maker who can answer questions and approve screens.
- Your brand assets, or a plan to create them with our graphic design team.
- Access to the systems the app connects to, plus any API documentation.
- Apple Developer and Google Play accounts in your company's name. We can walk you through setting them up.
- Time to test builds and give feedback each cycle.
Need an in-house developer after launch? A dedicated remote mid-level developer can keep building alongside your team.
When this is the wrong fit
If customers will only visit once, a fast mobile-friendly website usually beats an app. See small business website development. If you want a full-featured app built without a scope, written feedback or testing time, we are not the right partner.
FAQ
Do I own the app and the code?
Yes. The code, design files and store accounts belong to your company. We work in repositories and accounts you control.
Should my app be native or cross-platform?
Most business apps work well as cross-platform. We recommend native when the app depends on deep device features or heavy graphics, and we explain the tradeoff in your scope.
Can the app connect to my existing systems?
Usually, yes. Apps can connect to CRMs, payment processors, booking tools and databases through their APIs. We confirm each integration during discovery.
Who handles App Store and Google Play review?
We prepare the listings and submit the builds, then fix anything the reviewers flag. You keep the accounts and approve what goes live.
How much does a mobile app cost?
It depends on screens, platforms and integrations. We price from a signed scope and go over it with you on the fit call.
