Mobile Applications, explained.

Mobile Application Development is the design, engineering and release of apps that run natively on iOS and Android phones and tablets. It matters because a mobile app is held to a higher standard than a website: people expect it to open instantly, work on a weak connection, and not drain the battery, and the app stores will reject one that doesn't meet their rules.

Esscentra builds iOS and Android apps from a single cross-platform codebase where that serves the product, and goes native for the parts that need it, such as camera, payments or background location. We design offline-first so the app keeps working on a bad network, wire in push notifications, deep links and analytics, and connect the app to your existing backend or build one alongside it. Store listings, review guidelines and release builds are handled as part of the project, not left for you to discover at the end.

The result is an app that passes review the first time and behaves well in people's hands. It fits businesses giving customers a mobile way to order, book or track; field teams that need an app that works offline; and products moving from a mobile website to a proper app.

Who it's for

Built for teams like these.

  • 01

    Businesses that want customers to order, book, pay or track from their phone.

  • 02

    Field and operations teams that need an app that works without a reliable signal.

  • 03

    Products outgrowing a mobile website and needing notifications or device features.

  • 04

    Startups launching a mobile-first product on both platforms at once.

How we work

6 steps, from first call to launch.

  1. 01

    Flows & screen map

    We map who uses the app, what they do in it, and which screens and states that needs.

  2. 02

    Design for touch

    We design for thumbs, small screens and both platforms' conventions, then test it on real devices.

  3. 03

    App & backend build

    We build the app and the APIs it depends on in parallel, with offline storage and sync from the start.

  4. 04

    Device testing

    We test across screen sizes, OS versions and poor networks before anything goes to review.

  5. 05

    Store release

    We prepare listings, screenshots and privacy details and see both apps through store review.

  6. 06

    Launch & updates

    We monitor crashes and usage after launch and ship fixes and improvements on a regular cycle.

Questions

Questions about mobile applications.

How much does a mobile app cost?
You get a fixed-price proposal after a free discovery call. The price depends on the number of screens, the features that need native device access, and whether a backend needs building too.
Do you build native or cross-platform apps?
Usually cross-platform, so one codebase serves iOS and Android and updates ship to both at once. We use native code for the specific features that need it, such as advanced camera or background tasks.
How long does it take to build an app?
Most apps take 8 to 16 weeks from kickoff to store release. A focused app with a handful of core flows sits at the shorter end; an app with payments, real-time features and a new backend takes longer.
Will you publish the app to the stores?
Yes. We prepare the listings and privacy details, submit both apps and handle reviewer feedback. The apps are published under your own developer accounts so you own them.
Can the app work offline?
Yes. We design offline-first where it matters, storing data on the device and syncing it when the connection returns, so people can keep working in the field.
