Mobile app development for iOS and Android, from idea to launch.
Credantic is a mobile app development company for businesses that need an app their customers or staff will actually use. We build for iOS and Android, usually from one cross-platform code base, and build the back-end services the app depends on.
iOS, Android and cross-platform apps
We build iOS apps and Android apps. For most business apps we recommend a cross-platform approach so one code base serves both stores, keeping cost and maintenance down. Where an app needs deep device features, we build native components for those parts.
What we build
- Customer-facing apps for bookings, orders and accounts
- Field and staff apps that work offline
- Companion apps for an existing web platform
- Back-end APIs, sign-in and push notifications
From idea through launch
A clear process keeps the app small enough to launch and good enough to keep.
Our process
- Shape the idea: users, the one job the app must do well, and what can wait
- Design: screens you can click through before code is written
- Build and test on real devices, iOS and Android
- Store submission: listings, privacy details and review
- Launch, measure and improve
Do you need a mobile app, or will a mobile website do?
An app earns its place when people use it often, or when it needs something a browser cannot give it. Build an app when you need:
- Push notifications that people act on
- Offline use, for staff in places with poor signal
- The camera, location, Bluetooth or biometrics
- A task people repeat daily, where speed matters
A responsive website is often the better first step when use is occasional, the content is mostly reading, or you want to reach people without asking them to install anything. We build those too: see web development. Many apps also need a back end and an admin side, which falls under custom software development.
When should you not hire us for a mobile app?
- The app is a game or depends on 3D graphics or augmented reality.
- You want a visual identity and brand work done as part of the app. We build to a design, and you may want a design studio for that.
- You need a large team to ship several apps at the same time.
- The app only repeats what your website already does. Improve the website first.
- You have not decided who will use it. We would start with a short technology consulting review of the idea.
What do you get at each stage of an app project?
- Shape: a written description of the users, the one job the app must do, and the features that wait for a later version.
- Design: clickable screens you can test with real users before code is written.
- Build: a working app on real iOS and Android devices, with the source code in a repository under your account.
- Test: checks on a range of devices and operating system versions, and a beta for your own team.
- Store submission: listings, screenshots, privacy declarations and the build, handled with you through review.
- Launch and after: crash reporting, a plan for operating system updates, and a written support arrangement.
Native or cross-platform: which should you choose?
A cross-platform app shares most of its code between iOS and Android, which lowers the cost of building and of keeping both versions up to date. A native app is written separately for each platform and gives the deepest access to the device. The common cross-platform options are .NET MAUI, Flutter and React Native. The right one depends on the device features you need, the skills already in your business and who will maintain the app. We recommend one in writing and give the reasons.
What drives the cost of a mobile app?
- The number of screens and the complexity of each
- Whether you need iOS, Android or both
- Offline use and data synchronization
- The back end: accounts, a database, an admin tool and APIs
- Device features such as camera, location or Bluetooth
- Integrations with systems you already run
- Store review requirements and the length of the support period
We do not publish prices. You receive a fixed price or a rate with a ceiling in the written scope. Apple and Google charge their own developer account fees, which you pay in your account.
What are the risks, and how do we reduce them?
- The store rejects the app. We prepare the listing and privacy declarations early and follow each store's published review guidelines.
- The app is too big for a first release. We cut to the one job it must do and defer the rest.
- Operating system updates break features. Support terms cover fixes for new OS versions.
- You lose control of the app. The store accounts and the code are in your name.
- Users do not return. Basic usage measurement is in the first release, so you can see what people actually do.
How do you choose a mobile app development company?
- Will the store developer accounts be in your name? They should be.
- Do they recommend native or cross-platform with reasons, or only the one they know?
- Can you test a prototype before the build begins?
- Who builds the back end, and who will maintain it?
- Are updates for new iOS and Android versions part of the support terms?
- What can the firm show? We were formed in 2026 and have no published client apps yet, so judge us on the written scope, the prototype and the process. Ask every firm the same question.
