Mobile App Development — Native & Cross-Platform, Shipped to Both Stores

Ujjwal Technolabs builds production mobile apps for both the App Store and Google Play — using Flutter for cross-platform speed, or native Swift/Kotlin when a product demands it. Founded by Deepak Nagar, a full-stack engineer with 12+ years of experience, we ship the app, its backend, and deployment from one team, so nothing falls between the seams.

What we build with mobile apps

Mobile is one of our daily-driver disciplines, not a side offering. We design and ship complete apps — not prototypes that stall before review submission. Typical work includes:

• Cross-platform Flutter apps — one codebase, native performance, both stores. This is how the three apps powering FlexiCommerce are built (storefront, admin, and delivery).
• Native iOS (Swift) and Android (Kotlin) when a product needs platform-specific depth — advanced camera, background processing, or tight OS integration.
• App + backend together — Laravel/Node APIs, real-time data, push notifications, offline sync, and secure auth, all owned by the same engineers who build the app.
• Field and operations apps — inspection, logistics, data-capture, and on-site tools that work with patchy connectivity (we've shipped a Flutter + Next.js field-inspection app for a Brazilian client, now in production).
• Payments and commerce — Razorpay, Stripe, PayU, and PhonePe integrated and live in real apps.
• App Store and Play Store submission — we handle the review process, store listings, and the inevitable rejection back-and-forth.

Where mobile apps fit

A native or cross-platform app is the right call when your product genuinely needs the phone — not just a smaller website. Mobile earns its keep when you require:

• Reliable offline behaviour and on-device data capture (field work, inspections, logistics).
• Camera, GPS, sensors, biometrics, or barcode/QR scanning.
• Push notifications that actually re-engage users.
• A home-screen presence and store distribution your customers expect.
• Smooth, fast interaction that a mobile browser can't match.

For most products, Flutter gives you both stores from one codebase with near-native performance — the pragmatic default. We reach for native Swift or Kotlin when a single platform-specific capability is core to the experience and a shared codebase would compromise it.

Our proof

We don't just build mobile apps for clients — we run our own. FlexiCommerce, our flagship multi-tenant e-commerce SaaS, ships three native Flutter apps alongside its web platform, backed by ~500 API endpoints and 187 data models. It was built solo in roughly 2.5 months across ~450,000 lines of code — which means we've lived the full lifecycle of mobile apps in production with paying customers, store submissions, and real-world payment flows.

On the client side, an app we built passed 10,000+ downloads, and our Brazilian client's field-inspection app (Flutter + Next.js + Supabase) is in production today. That's the honest extent of our mobile track record — real, shipped, and verifiable, not a portfolio of mockups.

Is a mobile app the right choice for you?

We'd rather tell you the truth than sell you the wrong thing. A mobile app is a great fit when you need device hardware, offline reliability, push engagement, or store distribution — the things a browser simply can't do well.

But a mobile app is often not the fastest path to value. If your audience reaches you on desktop, if your product is content- or dashboard-heavy, or if you're still validating demand, a responsive web app (or a progressive web app) will get you to market faster and cheaper, and it updates instantly without store review. Many of our SaaS builds start web-first and add native apps once usage justifies it. If you're unsure, we'll say so before you spend on two platforms you don't yet need.

We're remote-first and work worldwide, and we're not locked to one stack — we build with whatever the product actually needs.
