PROBLEMS WE SOLVE

Most app projects fail long before launch.

Founders come to us with half-built products, rejected submissions, and code no one can continue. Here is what we fix and how.

The problem

You have an idea and you're ready to build, but you need a team that won't cut corners.

How we fix it

We shape your vision into a real product, starting with a clear plan and a design users actually want to use.

The problem

Your previous developer didn't deliver and the app is incomplete or buggy.

How we fix it

We assess what exists, then continue or rebuild, whichever genuinely serves you better.

The problem

Apple or Google rejected your app and you're stuck.

How we fix it

We know why these rejections happen, then restructure, rebuild, and resubmit so your app gets approved with its core idea intact.

The problem

The app was built on a foundation that can't scale as you grow.

How we fix it

We plan scalability from the architecture stage, so 100 to 100,000 users doesn't mean a full rebuild.

The problem

You're not sure whether to build for iOS, Android, or both.

How we fix it

We give an honest recommendation based on your audience and budget, and cross-platform covers both when it fits.

The problem

Vague estimates and surprise costs midway through have burned you before.

How we fix it

We give a fixed price after understanding your requirements, with no surprise additions partway through.

Why Zarle

We build apps differently.

Clear product vision, a design users want, and a submission process that understands exactly what Apple and Google require.

01

App Store specialists

Store compliance is built into our process from day one, not bolted on at the end. We know the policies category by category.

The honest technology call

We tell you whether cross-platform or native fits your product and budget. You're never pushed toward what's easier for us.

Rejection recovery

We restructure, rebuild, and resubmit rejected apps without losing the core idea you started with.

Scalable architecture

Scalability is planned from the architecture stage, so growth doesn't force a full rebuild later.

Fixed price, clear timelines

A fixed quote after we understand your requirements, with timelines set before we start.

Real device testing

We test across real devices, screen sizes, and OS versions before anything goes near a store.

You own everything

The code, the store accounts, and the assets belong to you from day one. Nothing is locked to us.

Post-launch support

Bug fixes, performance monitoring, and updates after launch, plus help when you're ready to add features.

WHAT YOU GET

Everything you receive.

From first wireframe to a live store listing, with the code and accounts handed to your team.

  1. 01

    Product Discovery

    We understand your idea deeply: who it's for, the problem it solves, and what the App Store requires for your category. This prevents the expensive mistakes that happen later.

  2. 02

    UX Flow & Wireframing

    We map out every screen and every interaction before visual design begins. You see the complete flow of your app before a single pixel is designed.

  3. 03

    UI Design

    We design every screen with the platform's native patterns in mind, brand-aligned and built to pass store review guidelines on design.

  4. 04

    Development

    Cross-platform with Flutter or React Native, or native, whichever fits your product. Clean, documented, scalable code, in weekly sprints.

  5. 05

    Testing

    We test across real devices, screen sizes, and OS versions. Functionality, performance, and edge cases, all covered before anything goes near a store.

  6. 06

    App Store & Play Store Submission

    We create your listings, write descriptions, produce graphics, set up policy pages, and manage the whole submission, meeting every requirement before submitting.

  7. 07

    Launch & Handover

    You go live and own the code, the accounts, and the listings. We're available for post-launch support, but you're in full control.

CROSS-PLATFORM & NATIVE

The right technology for your app, not just the one we know best.

We build across platforms and choose what's right for your product. We'll tell you which approach fits and why.

LET'S BUILD

Have an app idea? Let's see if we're the right fit.

Tell us what you want to build. We'll give you a straight assessment of what it takes, what it costs, and how long it'll take, before you commit to anything.

No pitch decks · No pressure · Just an honest conversation

Real questions. Straight answers.

Still not sure about something? Ask us directly, we usually reply within a business day.

Costs vary with complexity, platform, and features. A focused MVP for a single platform costs far less than a full-featured, multi-platform product. We give you a fixed price after understanding your requirements, with no vague estimates or surprise additions midway through. We also make sure you're not building more than you need at your current stage.

It depends on your audience and budget. If your users are primarily on one platform, start there. If you need both, cross-platform development with Flutter or React Native reaches both audiences without doubling costs. We give an honest recommendation based on your specific product and market.

Cross-platform apps built with Flutter or React Native run on both iOS and Android from one codebase, which is faster and more cost-effective. Native apps are built separately for each platform and offer deeper integration with device features. We'll tell you which one actually fits your product, not which one is easier for us to build.

A focused MVP typically takes 8 to 16 weeks. A more complex, multi-featured product takes longer. Timelines depend on scope, the speed of design approvals, and how many revision cycles are needed. We set clear timelines before we start and communicate proactively if anything changes.

Yes, and this is something we specialise in. Rejections almost always come down to specific policy violations or missing requirements for your app category. We assess what caused the rejection, restructure what needs to change, and resubmit, keeping the core idea of your product intact.

We assess what exists first: the code quality, the architecture, what can be continued, and what needs to be rebuilt. We give you an honest evaluation before any work begins. Sometimes continuing is the right call, sometimes starting clean saves more time and money. We'll tell you which.

Yes, completely. We manage store listing setup, app descriptions, screenshots and graphics, policy pages, category-specific compliance, and submission. We know what each store requires and handle it so you don't have to learn it yourself.

Completely. The code, the store accounts, and the assets belong to you from day one. You're never locked into working with us, and everything is documented and transferable if you ever hand development to someone else.

Yes. Scalability is planned from the architecture stage, not retrofitted later. Whether you grow from 100 to 100,000 users, the foundation supports that growth without requiring a full rebuild.

Yes. We offer post-launch support for bug fixes, performance monitoring, and updates, and we're there when you're ready to add new features or expand to a new platform.
