Engineering

Apps your users open every day.

Native and cross-platform apps for iOS and Android — designed, built, submitted and supported.

Sound familiar?

  • Your customers keep asking for an app and your competitors already have one.
  • You built an app two years ago and nobody uses it because the onboarding loses them.
  • Maintaining separate iOS and Android codebases has doubled your cost and halved your release pace.

If any of those land, this is the page for you. Here's how we approach it.

What you get

What mobile app development actually changes.

01

One codebase, both platforms

Cross-platform where it fits, which typically cuts cost by 30–40% and keeps both stores on the same version.

02

Native where it counts

When you need camera, sensors, background processing or serious performance, we go native rather than fight the framework.

03

Onboarding that doesn't lose people

The first ninety seconds decide whether an app gets a second open. We design for that specifically.

04

Works on low-end devices

Tested on the mid-range Android phones your users actually own, not just the newest iPhone.

05

Store submission handled

App Store and Play Store listings, screenshots, review responses and the rejections that come with them.

06

You can see what's happening

Analytics, crash reporting and funnels wired in from launch, so decisions are based on data.

What's included

Everything in the engagement.

iOS & Android

Both platforms from one project, released together.

Offline support

Works without a connection and syncs cleanly when it returns.

Push notifications

Segmented, scheduled and measured — not blasted at everyone.

Payments

Razorpay, Stripe, UPI and in-app purchases where the stores require them.

Authentication

Phone OTP, email, social login and biometric unlock.

Maps & location

Live tracking, geofencing and route optimisation.

Analytics

Funnels, retention and crash reporting from day one.

Store deployment

Submission, review handling and phased rollouts.

FAQ

Mobile App Development questions.

Still have one? Talk to an engineer, not a salesperson.

Flutter for most apps — one codebase, excellent performance, fast to build. React Native if you already have a React team and want to share knowledge. Native when you need heavy device integration or the last few percent of performance. We recommend based on your situation, not our preference.

A focused first version is 10–16 weeks including store submission. A complex app with payments, real-time features and an admin panel runs 5–8 months.

A well-built first version typically starts around ₹12 lakh. Complex apps run considerably higher. Be cautious of quotes far below that — they usually mean juniors, no testing, and a rebuild within eighteen months.

Yes, including the listing copy, screenshots, privacy declarations and the rejections that are a normal part of the process. Apple in particular will reject a first submission for something minor.

Ninety days of support are included. Apps need more ongoing attention than websites — OS updates, store policy changes and device fragmentation all force periodic work, so most clients keep a retainer.

Often, yes. We start with a paid code audit so both sides know what we're inheriting. Sometimes the honest answer is that a rebuild costs less than a rescue, and we'll tell you if that's the case.
