Native Mobile Apps, Engineered in Flutter

One codebase, two real native apps — iOS & Android. We design, build, and ship custom Flutter applications, and when a project fits, we deliver it faster on AppMinCMS, the app platform we built ourselves.

Two ways to build

Custom Flutter — or the platform we built ourselves

Most agencies sell you the only thing they have. We have two delivery paths — so our recommendation is based on your project, not our limitation.

PATH 01 — CUSTOM ENGINEERING

Custom Flutter Development

A fully custom native app, engineered for your exact product: your own backend, your integrations, your logic, your design system.

Best fit:  unique products, startups, complex workflows, apps that ARE the business.

Fastest Delivery

PATH 02 — PLATFORM DELIVERY

AppMinCMS-Powered Apps

Business apps assembled from proven modules — bookings, ordering, documents, payments, loyalty — on the no-code platform our team built and maintains.

Best fit: salons, clinics, restaurants, client portals, radio — apps that support the business.

Our honest-path promise: in your first consultation we'll tell you which path fits — even when the answer is the cheaper one. We built AppMinCMS precisely because most business apps don't need custom development. Yours might. That's what discovery is for.

Why Flutter

One codebase. Two native apps.Zero compromise.

Flutter lets us build iOS and Android from a single codebase without the quality penalty of old hybrid frameworks — real native performance, native feel, and full access to device features.

For you, that means roughly half the build and maintenance cost of two separate native teams, perfectly consistent apps on both stores, and one place to fix and improve.

We learned this the hard way. ZeltaCode spent years building on a legacy hybrid platform — until Apple's tightening App Store rules made it unsustainable. We rebuilt our whole delivery on Flutter. Keeping apps compliant with Apple & Google's evolving requirements isn't a checkbox for us; it's the reason we exist in our current form.

Native performance

Compiled code, 60fps UI — not a website in a shell.

App Store & Play compliance, maintained

SDK updates, privacy rules, review requirements — handled as a first-class priority.

One team, one codebase

Faster builds, cheaper maintenance, identical features on both platforms.

Backed by Google

Flutter powers apps for Google, BMW, Toyota, and millions of published apps.
