iOS, Android & cross-platform

Mobile apps built for daily use, not just app-store screenshots.

We design and build native-quality mobile apps for iOS and Android — most often from a single cross-platform codebase — so the product your users open every day is fast, reliable and genuinely useful, not a wrapped website.

Why it works
One codebase, both stores

Flutter and React Native let us ship iOS and Android together without doubling the engineering cost.

Built for retention

Onboarding, push and offline behaviour designed around the habit you want to build, not just the feature list.

Store-ready

We handle App Store and Play Store submission, review requirements and release management.

Supported after launch

OS updates, device fragmentation and crash monitoring don't stop being your problem at launch — we stay on it.

What we provide

Every offering under app development, in one place.

01

iOS App Development

Native-quality iOS apps built to Apple's platform conventions and performance expectations.

02

Android App Development

Android apps that handle the device and OS-version spread your users actually have.

03

Cross-Platform Development

Flutter and React Native builds that share one codebase across iOS and Android without a compromised feel.

04

Custom Mobile Applications

Purpose-built apps for a specific workflow — coaching, field operations, member portals — not a generic template.

05

App UI/UX Design

Interaction and interface design for mobile-specific patterns: gestures, offline states, notifications, onboarding.

06

App Maintenance & Support

Ongoing releases, OS-compatibility updates and monitoring so the app stays healthy as platforms change under it.

How it runs

Our process for app development.

01

Discover

We define the core workflow the app has to nail and the platforms it needs to run on.

02

Design

Mobile-first UX: flows, states and the design system, prototyped and tested before a line of app code is written.

03

Build

Two-week increments with a real device in your hands every demo, not just a Figma link.

04

Ship & support

Store submission, release management, and a support plan for the OS updates that never stop coming.

Straight answers

Questions about app development.

Flutter or React Native — which do we need?

Both ship native-quality cross-platform apps well. We recommend based on your team's existing stack, the specific device APIs you need, and long-term maintenance plans.

Do we need separate iOS and Android teams?

Usually not. Cross-platform development covers the large majority of app requirements from one codebase — we'll flag the rare cases that genuinely need native code.

Who submits the app to the stores?

We handle submission and review requirements, under your developer accounts, so you keep full ownership.

What happens after launch?

Apps need ongoing maintenance as OS versions ship. We offer a support plan, or hand over a well-documented codebase if you'd rather bring it in-house.

Vaible didn't just build what we asked for — they told us what we actually needed, and it worked.

One shared board, weekly demos, no surprises. It's the first engagement that felt like an extension of our own team.
