What We Build

Native

Mobile Apps (iOS & Android)

Native apps built for one or both platforms, with full access to device features and the best possible performance.

  • Best forPerformance-critical or platform-specific apps
  • Trade-offHigher cost if building both platforms
Cross-Platform

Cross-Platform Apps

One codebase, built with frameworks like React Native or Flutter, deployed to both iOS and Android.

  • Best forMost startups & MVPs
  • Trade-offFaster & cheaper, minor performance cost
Web App

Custom Web Applications

Browser-based applications and internal tools that don't need to live in an app store at all.

  • Best forDashboards, portals & internal tools
  • Trade-offNo offline access or deep device integration

How It Works

Our App Development Process

Seven stages, from first conversation to a live app you actually own.

01

Discovery & Scoping

We map the problem you're solving, your users, and the core features that need to be in version one.

02

UI/UX Design & Prototyping

Screens are wireframed and designed, then turned into a clickable prototype you can review before development.

03

Architecture & Tech Stack

We choose native, cross-platform, or web-app architecture based on your users and budget, not by default.

04

Development in Sprints

The app is built in short, reviewable sprints, so you see working progress regularly.

05

QA & Testing

Tested across real devices and OS versions for crashes, performance issues, and edge cases before launch.

06

Store Submission

We prepare listings and manage the submission and review process on the App Store and Play Store.

07

Post-Launch Support

Optional maintenance plans cover OS updates, bug fixes, and monitoring after the app is live.

  • Timeline6–10 weeks
Full-Featured

Full-Featured App

A complete consumer or business app with the full feature set, ready for public launch.

  • ScreensFull feature set
  • PlatformiOS & Android
  • Timeline3–6 months
Enterprise

Enterprise / Custom Platform

A larger custom-built system integrating with your existing business tools and workflows.

  • ScreensCustom-scoped

Why It's Worth Doing Properly

Why a Custom App Matters

A direct channel to your users — not filtered by a platform's algorithm
Push notifications bring users back without paid ads
Built around your exact workflow, not a generic template
Offline access & device features a website can't offer
Usage analytics tell you exactly how the app is being used
An owned asset you can improve, scale, or sell over time
A presence in the App Store & Play Store builds credibility
Integrates with payment gateways, APIs & internal systems
Decide Faster

Native vs Cross-Platform vs Web App

TypeBest ForDevelopment CostPerformance
NativeNative AppPerformance-critical or platform-specific appsHigher — separate iOS & Android buildsBest possible
CrossCross-Platform AppMost startups & MVPsLower — one shared codebaseVery good for most app types
WebWeb AppDashboards, portals & internal toolsLowest — no store submission neededGood, browser-dependent

Most consumer apps launch cross-platform first and only go native later if performance genuinely demands it. Talk to us about which fits your idea.

Why Legalkarobar.com

Why Founders Choose Legalkarobar.com for App Development

We scope honestly before we build, so the app you get actually matches what you needed.

We scope before we quote

A clear discovery phase means the quote you get actually matches what gets built, not a number padded to cover unknowns.

One team for your app and your business setup

If you're also incorporating, registering a trademark, or setting up GST with us, your app development runs alongside the rest of your launch. See our company incorporation service.

MVP-first, when that's the right call

We'll tell you honestly if a smaller first version gets you real user feedback faster than building everything up front.

You own the code, not just the app

Full source code and assets are handed over on delivery — you're never locked into us for every future change.

Questions, Answered

Frequently Asked Questions

A focused MVP with core functionality typically takes 6–10 weeks to design, build, and test. A full-featured app with a broader set of screens and integrations usually takes 3–6 months, and the timeline stretches further for complex, enterprise-grade platforms.
It depends on where your users actually are — if you don't know yet, cross-platform development lets you launch on both iOS and Android from a single codebase, which is usually the more cost-effective starting point for a new app. If your audience is clearly concentrated on one platform, building natively for that platform first can make sense.
A native app is built separately for iOS (Swift) and Android (Kotlin), giving the best possible performance and access to platform-specific features, but at roughly double the development cost of a single codebase. A cross-platform app, built with frameworks like React Native or Flutter, shares one codebase across both platforms, which is faster and cheaper to build and maintain, with a small trade-off in raw performance for most app types.
Yes. We prepare the store listings, screenshots, and metadata, and manage the submission and review process on both the Apple App Store and Google Play Store, including responding to any reviewer feedback that comes back.
Yes, and we usually recommend it — an MVP with just the core functionality lets you get the app in front of real users and validate the idea before investing in the full feature set. Most of what we learn from an MVP launch directly shapes what gets built next.
Optional maintenance plans cover OS updates, bug fixes, and minor changes after launch, since both iOS and Android update frequently enough that an app needs occasional maintenance just to keep working smoothly. Larger feature additions are scoped and quoted as separate work.
Yes. Once the project is delivered and paid for, the source code and any custom assets belong to you, and we hand over full access rather than keeping you tied to us for every future change.
Yes. A progressive web app or browser-based application can be a faster, cheaper alternative to a native app for many use cases, especially if your users don't need offline access or deep device integration like camera or push notifications. We can advise which approach actually fits what you're trying to do.
