Mobile apps that ship to the stores, and keep working after launch.
iOS and Android apps in React Native, built with the back end, integrations and AI features they depend on, by the same senior team that runs them after launch. Published: a HIPAA-compliant telehealth app with three EHR integrations, $124,000 in five months.
What a mobile app development company should build besides the app.
The app is the part users see. Most of the work, and most of the risk, sits behind it: the API, authentication, data storage, push notifications, integrations with the systems that already run the business, and the release process for two app stores. Gigabit builds all of it as one system, in React Native so one codebase serves iOS and Android, and adds AI features (assistants, document capture, summaries) where they earn their place.
The published example is a patient app for a chronic-care company: daily vitals logging, secure messaging and video visits, designed for an older population with 18px minimum fonts and 48px touch targets, plus a provider dashboard and bidirectional integration with Epic, Cerner and athenahealth. It cost $124,000, launched a week ahead of a five-month deadline, enrolled 1,200 patients in 90 days and lifted daily vitals adherence from 34% to 78%.
What we build for a mobile product.
One team for the app, the back end and the release pipeline, so nothing falls between vendors.
Cross-platform apps
React Native apps for iOS and Android from one codebase, with native modules where a device feature needs them.
Back end and APIs
The API, database, authentication and file storage the app talks to, built for the load and the compliance rules you have.
Integrations
Payments, CRM, EHR, ERP and calendar systems connected, so the app works with how the business already runs.
AI features
Assistants, photo and document capture, summaries and search inside the app, with evaluations and cost limits.
Security and compliance
Encryption, role-based access, audit logs and session controls, including HIPAA-aware set-ups for health data.
Release and operations
App Store and Google Play submission, crash reporting, analytics and over-the-air updates for fixes between store releases.
From workflow to store listing.
Map the workflow
Watch the people who will use the app, then cut the feature list to the first release. It ends in a fixed price.
Build
Two-week sprints with a test build on your phone every Friday.
Launch
Security review, store submission and monitoring live before the first users sign in.
Run
Keep the team for updates and new features, or take it in-house with the code and runbooks.
Published prices, mapped to the job.
Every price here is the same one on the pricing page. Work with no published price gets a fixed price in writing before it starts.
Figures in the notes are what past clients paid, from the published case studies; they show the range, not a rate card. Work with no natural end, such as ongoing development, is priced per engineer per month with no lock-in.
When to hire us for this, and when not to.
- The app is part of how you deliver the service, not a brochure.
- It has to talk to systems you already run: CRM, payments, EHR or ERP.
- You need iOS and Android and would rather maintain one codebase.
- Someone on your side can test a build each week.
- A responsive website would do the job. Build that first; it costs less and needs no store approval.
- It is a game or depends on heavy 3D graphics. Hire a specialist game studio.
- You need a native-only app for one platform with deep platform APIs on day one. Ask us, but a native specialist may fit better.

Mobile app development, answered
How much does it cost to build a mobile app?
Our published telehealth platform, a React Native patient app with a provider dashboard, three EHR integrations and HIPAA compliance, cost $124,000 over five months. Simpler apps with fewer integrations cost less. You get a fixed price in writing after scoping, and work after launch runs on an embedded team at $3,000–$7,500 per engineer per month.
Do you build native iOS and Android apps or cross-platform?
We build in React Native, so one codebase ships to both stores, and write native modules where a device feature needs them. For most business apps that halves the work of maintaining two apps. If your app depends on deep platform-specific features from day one, we will say so during scoping.
How long does it take to build an app?
The published telehealth app took five months, including three EHR integrations, a third-party security assessment and store launch. A focused first release with one core workflow takes less; you get the timeline with the fixed price after scoping.
Do you handle App Store and Google Play submission?
Yes: store listings, review submission, release builds and the fixes reviewers ask for, plus crash reporting and analytics so you can see how the app behaves after launch.
Can you take over an app someone else built?
Yes. We start with a review of the code, back end, security and release process. Apps built with AI coding tools start with the $2,500 Prototype Production Review, credited to the build if you go ahead.
