Mobile AppsNative-feeling. Built to ship.

iOS, Android, and cross-platform — offline-first, biometric-secured, push-aware, store-ready. Built on a shared TypeScript codebase with native escape hatches when you need them.

02What we build

What we ship. Every kind of app.

Categories that cover the full range of what “a mobile app” means in 2026 — from a launch-day consumer brand to a hardware companion app for a connected device.

For connected devices

IoT & Connected Apps

Companion apps for hardware — smart home, wearables, industrial sensors. BLE / Wi-Fi onboarding, real-time control, and fallback modes.

03Challenge & Solution

Common problems, honest answers.

The pain points we hear on almost every mobile-app kickoff call, and the way we solve each one. No magic — just the right architecture done with care.

Phones live in pockets, not in dev consoles. We build for the device the user actually has, on the network they actually have it on.

Honest fixes for common challenges. Same playbook on every engagement, calibrated to the size of your build.

04Why Devsoleil

What you can expect, on every project.

Native-feeling UX, offline-first sync, push and biometrics wired in, performance on real devices, and a store submission that lands first try.

Native-feeling on every platform

Platform-aware components, gesture conventions, system fonts, and animation budgets that match each OS — without a separate codebase per platform.

Shared TypeScript codebase

One language, one design system, one logic layer across iOS and Android. Native modules only where the gain is worth the maintenance cost.

Push, deep links, and background sync

Notifications, universal links, scheduled background tasks — wired in, scoped per platform, and honour Do Not Disturb.

Biometric & secure auth

Face ID, Touch ID, fingerprint, plus secure enclave / keystore-backed token storage. Compliance-ready for finance and health surfaces.

Performance on real devices

Tested on a 3-year-old Android too — animation budgets, image pipelines, lazy bridges. The cheapest target device gets a 60fps experience.

Custom features

Flows your users actually ask for, on-device or cloud AI where it earns its keep, and the team past v1.

05AI-driven development

Built with AI. Driven by humans.

AI accelerates execution across every layer — UI, native modules, tests, store assets. Human judgement decides what gets shipped. Leverage, not replacement.

  • 01

    Agentic AI workflows

    Multi-step agents that plan, execute, and self-correct on cross-platform tasks.

  • 02

    AI-assisted development

    Pair-programming with Claude on RN screens, Swift modules, Kotlin services.

  • 03

    Faster iteration cycles

    Spec → prototype → on-device review in days, not weeks.

  • 04

    Automated review & testing

    AI-generated UI tests, snapshot regressions, and cross-device matrices.

Featured pipeline

Agent loop

Planning, execution, evaluation, and shipping — cost-capped, human-approved, eval-gated.

07How we ship

How we ship. No surprises.

Same workflow on every engagement, calibrated to project size. Discover, design, engineer, optimise, launch.

  1. 01

    Discover

    User journeys, device matrix, platform expectations, integrations. We map what the app must do, what the OS allows, and the gap.

    Design

    Native-aware design system — gestures, type, spacing tuned per platform. Every state designed before code, including offline + permission-denied.
