Who hires a mobile app development company like us
Most organizations that come to us as a mobile app development company do not need an app for its own sake. They need a channel that a web page or a phone line is not serving well, and the app has to sit on top of real operational systems, which is where most of the difficulty lies.
For a global healthcare organization, outpatient scheduling was rebuilt as one platform across web, mobile and the call center. App development cost is driven by user types, offline needs, integrations and the number of codebases rather than screens, so we quote after discovery. One honest note on scope: if your users open the app once a year, a responsive web app may serve them better and cost less to maintain. We raise that in discovery rather than after the build.
-
Patients booking by phone, walk-in and web form
With no shared view of the diary, each channel works from its own picture of what is available.
-
A loyalty program that lives on a card customers forget
When the card stays at home, the program is missing at the moment it is meant to matter.
-
Field teams working from messaging groups and photos of paper forms
Orders, visits and documents live in chats, where nobody can search, approve or report on them.
-
Customers asking for the core workflow on their phones
A SaaS product that only works at a desk misses the moments its users are away from one.
-
A web platform that needs apps without a second backend
Building iOS and Android against a separate backend duplicates business rules that already exist on the web.
-
A product that depends on location, camera or push from day one
Those device features sit at the center of the first release, so the product has to start on mobile.
The work
Inside a Mobile App Development engagement.
What our iOS and Android app development covers
-
Customer and patient apps
Booking, account management, reminders and self-service. Platforms of this type increase daily bookings by up to 40%.
-
Loyalty and engagement apps
Member profiles, rewards and personalized offers, as for a global hospitality brand that unified guest profiles with an Android app as one of the channels.
-
Partner and field apps
Onboarding, orders, visit logs and document capture for people who work away from a desk, often on patchy connections.
-
Companion apps for web platforms
The phone version of a workflow that already runs on the web, built against the same API so there is one source of truth.
How we approach iOS and Android app development
- 01
React Native and Flutter development, or native
Cross-platform suits most booking, commerce and business apps. React Native fits a React web team, Flutter renders consistently, and Swift or Kotlin earn their cost for intensive graphics, Bluetooth or camera work.
- 02
Offline behavior is an architecture decision
Field and healthcare users lose signal. What works offline, and how conflicts resolve on reconnect, is settled early, because adding it later means rewriting the data layer.
- 03
One backend, with the rules on the server
The app uses the same documented API as your web platform, so a policy change does not wait for users to update their apps.
- 04
Security on the device
Tokens in the platform keychain, sensitive data kept off the phone where the workflow allows, and sessions that expire. For healthcare and financial apps these are review points in every weekly demo.
- 05
Testing on real devices, notifications with a purpose
Builds are reviewed on the mid-range phones your users carry. Notifications are limited to the reminders, confirmations and status changes users want.
Where mobile app projects go wrong
-
App store rejection in launch week
Privacy disclosures and listing material are prepared during the build, and a beta build is submitted early to surface review issues.
-
iOS and Android apps that drift apart
A cross-platform codebase, or one shared backlog when native is right, keeps the two apps on the same features.
-
Business logic trapped in the app
Rules stay on the server, so a change does not need a store release or wait for users to update.
-
No plan for yearly OS updates
Apple and Google ship major releases every year, so the handover includes a maintenance plan or a pod that owns it.
-
Crashes found through store reviews
Crash reporting and analytics go live with the first beta, and staged rollouts limit how many users see a bad release.
How it runs
From first call to production.
-
Discovery
Who uses the app, where, and on what connection. We decide what must work offline and which device features the product depends on.
-
Prototype on devices
Flows tested on the phones your users carry, not only in a desktop browser, at least twice before build.
-
Technology and architecture
Flutter, React Native or native, decided against the tested design, with the API, sync and notification model written down.
-
Build and beta
Weekly builds on your phone, then a closed beta through TestFlight and Google Play testing tracks.
-
Store release and operate
Store submission, staged rollout, crash monitoring and a plan for OS updates, then handover or a pod for later releases.
Team and timeline
6–8 weeks
to store submission
Indicative. Actual duration depends on requirements and complexity, and can change.
Who works on it
- Product consultant
- UI/UX designer
- Two mobile developers
- Backend developer
- QA engineer on real devices
Engagement model
Fixed Cost for a scoped first release of around 6–8 weeks. Dedicated Team where the app ships updates continuously alongside a web platform.
Good to know
Fixed Cost suits a scoped first release; our patient booking platform ran 12 months as a fixed cost project. Dedicated Team or Time and Materials suits apps that ship continuously. You get a build on your phone every week.

FAQ
Mobile App Development: common questions.
Should I choose Flutter, React Native or native development?
Choose cross-platform unless the product depends on something the device does best. Flutter and React Native give one codebase for iOS and Android and suit most business, commerce and booking apps. Go native with Swift and Kotlin when the app relies on heavy graphics, advanced camera or Bluetooth work, or platform features that arrive before cross-platform frameworks support them.
What drives mobile app development cost?
Scope drivers, not screen count. The biggest are the number of user types, whether the app must work offline and sync later, how many external systems it integrates with, and whether one or two native codebases are needed. A shared backend with an existing web platform reduces effort considerably. We fix the price after discovery, against a signed first-release scope.
How long does it take to build a mobile app?
A focused first release typically takes 6–8 weeks from discovery to store submission. Apple and Google review comes after submission, which is why a beta build goes in early to surface review issues. Apps that sit inside a larger platform take longer. Our patient booking platform, spanning web, mobile and the call center, ran 12 months as a fixed cost project.
Do you handle App Store and Google Play submission?
Yes. We prepare store listings, privacy disclosures and screenshots, manage TestFlight and Google Play testing tracks, and handle review feedback. The apps publish under your developer accounts, not ours, so ownership is never in question. After launch we use staged rollouts, so a problem in a new version reaches a small share of users before everyone.
Can you add a mobile app to our existing web platform?
Usually, and it is often the most efficient route. If the web platform has a documented API, the app reuses the business logic and data already there. If it does not, we add an API layer first, which also helps partners and reporting tools. We check this in discovery, because a web backend coupled tightly to its screens changes the plan.
