Overview

How we help

Mobile work rarely happens at a desk. We build apps for field teams, customers, and internal users who need software that works in the warehouse, on a site visit, or on a spotty connection — not just on the office Wi-Fi.

We deliver native iOS and Android where the platform matters, and cross-platform React Native or Flutter where a single shared codebase serves you better. The choice follows your requirements, your timeline, and how much each platform needs to feel at home.

This is the consulting side of Mariyano, delivered by the same team that builds Zipflow, YokoCart, and our other products. Your app gets the same engineering standards, documented APIs, and long-term maintainability we hold our own products to.

Capabilities

What's included

Native iOS and Android

Apps built in Swift and Kotlin for the cases where platform-native performance, fidelity, and device features matter most.

Cross-platform builds

React Native and Flutter apps that share one codebase across iOS and Android, cutting cost and keeping both platforms in step.

Offline support

Local storage and sync so the app keeps working without a connection and reconciles cleanly once the device is back online.

Backend integration

Apps wired to your existing systems and our APIs, so data flows between the field and your back office without manual re-keying.

App-store delivery

We handle the App Store and Google Play submission process — builds, signing, review, and the practical details of shipping.

Built to maintain

Clean architecture, sensible defaults, and tested code, so the app stays reliable through OS updates and future changes.

How we work

Our approach

Understand the use

We start with who uses the app and where — the devices, the connectivity, and the real conditions it has to work in — before any code is written.

Choose the right build

We recommend native or cross-platform based on your requirements, then agree on scope, platforms, and a release plan you can rely on.

Design and build

We build in short, reviewable increments with working builds you can put on real devices, so feedback shapes the app as it takes form.

Ship and support

We take the app through store review and release, then support it through updates, OS changes, and the next round of improvements.

Use cases

Where it fits

Field service and inspections

Apps for technicians and inspectors who capture data on site, often offline, and sync it back once they are in range.

Customer-facing apps

Branded apps that give your customers a place to book, track, pay, or manage their relationship with your business from their phone.

Internal operations tools

Apps for warehouse, logistics, and on-the-floor teams who need fast, reliable mobile tools rather than a laptop and a browser.

Companion apps for existing systems

Mobile front-ends for software you already run, giving your team the parts they need most while on the move.

FAQ

Common questions

Should we build native or cross-platform?

It depends on your requirements. Native suits apps that lean heavily on device features or demand the highest fidelity per platform; cross-platform with React Native or Flutter is usually faster and cheaper when one shared codebase serves both stores. We will recommend the right fit for your case — talk it through with us at our contact page.

Can the app work without a connection?

Yes. We build offline support with local storage and sync, so the app keeps working in the field and reconciles its data once the device is back online.

Do you handle App Store and Google Play submission?

Yes. We manage builds, signing, store listings, and the review process for both the App Store and Google Play, and we support the app through later updates. Reach the team at [email protected] or via our contact page.
