Mobile App Development

Custom mobile apps that ship fast, not 4 quarters.

Native and cross-platform apps for businesses with 10–500 employees. Fleet and consumer platforms we've built are live in the app stores. Engineered for healthcare, fintech, education, logistics and consumer, by the founder, not a junior team.

What we build

Six capabilities. One team. One commit log.

Every project is staffed by the same engineers from kickoff through App Store submission. No handoffs, no offshore relay, production code from day one, your team gets GitHub access on week one.

01

Native iOS & Android

Swift / SwiftUI and Kotlin / Jetpack Compose. Production-grade architecture, not template-based, the same patterns that ship at scale on Fleet tracking platform.

  • SwiftUI + Combine, Kotlin coroutines
  • MVVM / Clean architecture
  • Offline-first, background sync
02

React Native / Flutter

Cross-platform when budget or speed demands it. Same UX, roughly half the build time, the right call when you're validating, not when you're scaling Instagram.

  • Expo & bare RN, Flutter 3
  • Native modules where it matters
  • One codebase, two stores
03

Backend APIs

Node.js, Python or Go. Custom auth, payments (Stripe, Razorpay, RevenueCat), real-time data sync, push notifications, wired to your app, not bolted on later.

  • REST + GraphQL + WebSockets
  • Stripe / Razorpay / RevenueCat
  • Postgres, Mongo, Firebase, Redis
04

AI-first features

Chat agents, voice transcription, document processing, recommendation engines, built into the app, not pasted in as a chat bubble. OpenAI, Anthropic, on-device where useful.

  • Voice → text → action pipelines
  • RAG over your data
  • On-device Core ML / ML Kit
05

App Store + Play Store launch

Compliance, ASO, beta testing via TestFlight and Play Console internal tracks. We handle the submission, the review tickets and the resubmission if Apple bounces it.

  • TestFlight + Play internal tracks
  • ASO copy, screenshots, previews
  • Privacy manifests, IDFA, ATT
06

Maintenance & growth

Post-launch retainer for bug fixes, OS updates and feature iteration, or we hand over a clean codebase and walk away, your choice. Cancel the retainer anytime.

  • Sentry + Crashlytics from day 1
  • Monthly OS-update guarantees
  • Feature roadmap, owned by you
The stack

The build cycle

A clear path to App Store.

No discovery-phase loops. No "Phase 0" that bills for 8 weeks. You leave the kickoff call with a written quote and a timeline, typically 4-8 weeks, scoped after discovery.

01

Discovery

A 30-minute call. We map your scope, audience and the one success metric that matters. You walk away with a quote, in writing, after the call.

02

Build

Weekly demos. Production code from day one. Your team gets GitHub access on day one, so review happens live, not at handover.

03

Ship

Submit to App Store and Play Store. Beta cohort tested on TestFlight. Crash reporting and analytics wired before the first real user lands.

04

Iterate, Month 2+

Optional retainer for ongoing development. Or we hand over a clean, documented codebase and walk away. No lock-in, no licensing on top.

Why us

Two things we won't compromise on.

There are a thousand mobile-dev shops on the internet. Two things are true about this one, and you can verify both before you sign anything.

01 · Verifiable proof

Real apps. Real users. Public proof.

Our fleet tracking platform runs on phones for fleet operators. Wikolo is live in the App Store and Play Store for university students. The apps are downloadable today, so you can check them yourself.

02 · Founder-led, no bait & switch

Founder reviews every commit. No junior swap.

Prakash personally reviews every commit and joins kickoff plus go-live for every project. The senior engineer who scopes your build also writes the foundational code and stays through submission. Same faces from week zero to App Store approval.

Proof in production

The app powering fleet operators.

One quick example. There are seven others in the App Store under our maintenance, case studies on request.

Frequently asked

Honest answers to the five questions every buyer asks.

If you have a question that isn't here, email Prakash directly. No SDR layer, no form-funnel, replies usually come back the same day.

What does a typical project cost?
We quote a scoped price for the build, a starter app with a basic backend and a complex build with custom integrations, real-time features or AI are very different projects. The discovery call confirms the price in writing before work starts, there's no scope creep clause, and we don't bill against time.
Do you sign NDAs?
Yes. We'll sign a mutual NDA before the discovery call if you'd like, just request it when you book the slot, and we'll send our template within the day.
Who owns the code?
You do. Full source-code and IP ownership, written into the contract. Source, repos, design files, App Store and Play Store accounts, all handed over to your jurisdiction (US, UK, UAE or India) on delivery and final payment. No licensing on top, no leverage held back.
What if I need ongoing updates?
Most clients move onto a maintenance retainer after launch. It covers bug fixes, OS-update tracking, security patches and a small feature iteration budget. Cancel anytime, no minimum term.
Can you take over an existing app?
Yes, we do this often. We start with a free one-hour codebase audit: architecture, dependency health, test coverage, store-listing status. From there we quote either a clean-up sprint, a full rework or a "leave it and ship features" plan. You pick.

Bring a problem. Leave with a quote.

Every Matrytech engagement starts with a 30-minute discovery call, with Prakash or a senior engineer, never an SDR. You bring the brief; you leave with a quote in writing after the call.
