Mobile apps people actually open.

Native iOS, native Android, and cross-platform Flutter or React Native apps — designed for App Store quality, fast cold starts, and long-term maintainability. From discovery brief to App Store listing, all under one roof.

Overview

What it means to work with us.

Mobile is unforgiving. A slow launch, a janky scroll, a missed dark-mode token — and the user closes the app, often forever. We build for that pressure: cold-start budget tracked weekly, considered offline behavior, and platform-native feel even when the codebase is shared between iOS and Android.

What we deliver

Capabilities & deliverables.

Every engagement is shaped to fit, but these are the building blocks we rely on.

01

iOS & Android Native

Swift and Kotlin when peak performance and platform fidelity matter. The premium tier of mobile development, deliberately chosen.

02

Flutter Cross-Platform

One Dart codebase, two App Stores, near-native feel. The most cost-effective path for many apps without sacrificing user experience.

03

React Native

When your team is already JavaScript-heavy. Familiar tooling, shared code with the web, and acceptable performance on most flows.

04

Backend & APIs

We build the server side too — authentication, push notifications, sync engines, payments, and analytics. One vendor, one contract.

05

App Store Submission

Listing copy, screenshots, video previews, ASO research, and review-readiness. We get the app live, often on first submission.

06

Post-Launch Support

Crash monitoring, A/B testing, OS upgrade compatibility, and feature iteration. Apps need ongoing engineering, and we plan for it.

Why it works

The SD Technolabs difference.

Two decades of practice sharpened into a way of working that respects both craft and clock.

01

Native feel always

Even cross-platform apps respect each OS's gestures, navigation patterns, and visual conventions. No lowest-common-denominator UI.

02

Cold start obsessed

Startup time is benchmarked weekly. Slow apps lose users in week one; fast apps earn week-four retention.

03

Crash-free as a metric

Sentry, Crashlytics, and dashboards on the wall. Quality is observable, debatable, and improvable — not vibes-based.

04

App Review savvy

We've shipped through every reviewer mood. Submissions pass first time more often than not, because we know what flags.
