ServicesMobile apps
iOS and Android apps, from first sketch to the App Store.
We design and build iOS and Android apps that feel at home on each platform — natively or cross-platform with Expo and Flutter — then take care of store review, release and the updates that follow.

Why Zero Horizon
What sets our mobile apps work apart
- 01
The right stack for the product
Native Swift and Kotlin, or one cross-platform codebase with Expo or Flutter — chosen for your product and budget, and always built to feel at home on the phone.
- 02
Store review handled
We have taken our own apps through App Store and Play review, and we manage submission, rejections and release for you.
- 03
Built to be updated
Every OS release changes something. The code is structured so updates stay small, safe and inexpensive.
How it runs
Four stages, one fixed price
- 01
Discovery
Establishing what to build, for whom, and why.
- 02
Design
Shaping the product before it is built.
- 03
Development
Building in short, reviewable stages.
- 04
Launch and support
Releasing with confidence, then staying close.
Our work
Mobile apps we have shipped
Native or cross-platform?
It depends on the product. Expo and Flutter let one codebase serve both platforms, which suits most apps and budgets; native Swift and Kotlin earn their cost when an app leans heavily on device features, widgets or performance. We recommend one with your quote and explain why.
Should we launch on iOS, Android or both?
Most clients launch on both. If the budget only stretches to one for now, we will look at where your users are and recommend which to start with, and structure the work so the second platform follows cleanly.
Who owns the App Store and Play Store listings?
You do. Listings are published under your developer accounts from the start, so the app, its reviews and its ratings always belong to your business.
What happens when Apple or Google release a new OS?
We test against every major release before it ships. Under an ongoing arrangement, compatibility updates are handled as part of the monthly work.
