- Manufacturers, distributors and field-sales teams replacing paper forms and spreadsheets with a staff app

What you can expect
- One codebase, two stores when cross-platform fits, or native builds when performance or device features demand it
- A clickable prototype before code, so scope and screens are agreed early
- A backend and admin panel your team can use to manage users, orders and content
- Store-ready builds with listings, privacy details and review submissions handled
- Source code, accounts and credentials in your name from day one
What’s included in an app project
Every engagement is scoped to your goals, but most projects combine the building blocks below. We tell you plainly which ones you need now and which can wait until users ask for them.
Native Android and iOS
Kotlin and Swift builds for apps that lean heavily on Bluetooth, background location, camera pipelines or other device-level features.
MVPs for startups
A focused first release covering the core user journey, analytics and crash reporting, so you learn from real usage instead of guesses.
E-commerce and booking apps
Catalogs, carts, Razorpay or Stripe checkout, slot booking, order tracking, coupons and push notifications tied to your existing store or system.
Business and field-staff apps
Attendance, site visits, order capture, inspections and photo uploads that keep working with patchy connectivity and sync when back online.
APIs and backend
Secure REST APIs and databases on Node.js, Firebase or Laravel, plus a web admin panel for your operations team.
Play Store and App Store publishing
Developer account setup guidance, store listings, screenshots, data-safety and privacy forms, and handling reviewer feedback.
Post-launch maintenance
OS-update compatibility, bug fixes, dependency upgrades, performance monitoring and small feature releases on a monthly plan.
Technology we use for mobile apps
We choose the stack based on your features, budget and the team that will maintain the app later, not on what is fashionable.

How we build your app
1
Discover & scope
Workshops on users, features and integrations; a written scope with a milestone plan.
2
Design & prototype
User flows and a clickable Figma prototype you can test with real people before development.
3
Build in sprints
Two-week sprints with a test build on your phone after each one, so progress is visible.
4
Launch & support
Store submission, launch monitoring and an optional maintenance plan for ongoing updates.
Engagement & pricing
A typical MVP takes 6–10 weeks from signed scope to store submission. Larger apps with multiple user roles, complex integrations or offline sync take longer and are planned in phases.

Mobile app development FAQs
Should I choose Flutter, React Native or native development?
For most MVPs, e-commerce and business apps, Flutter or React Native gives you Android and iOS from one codebase at a lower cost. We recommend native Kotlin or Swift when the app depends heavily on device hardware, background processing or platform-specific features. We explain the trade-offs during the free consultation.
How long does it take to build an MVP?
A typical MVP takes 6 to 10 weeks, depending on the number of screens, user roles and integrations. We share a milestone plan with dates once the scope is agreed.
How much does a mobile app cost?
App MVPs start from ₹1,50,000 or $3,000. The cost depends on features, design complexity, backend needs and integrations. Final quote after a free consultation.
Will you publish the app on the Play Store and App Store?
Yes. We prepare store listings, screenshots and privacy declarations, submit the builds and handle reviewer feedback. The developer accounts are created in your business name so you keep full control.
We are based in the US, UK or UAE. How do you work with international clients?
We work with clients across time zones using shared project boards, weekly video calls and test builds through TestFlight and Play Console testing tracks. IST overlaps with UK and European working hours, and we schedule calls in US mornings or evenings. Payments can be made via Wise, PayPal or international wire.
What happens after the app is launched?
We offer monthly maintenance plans that cover OS-update compatibility, bug fixes, dependency upgrades and small feature releases. You can also take the code to your in-house team at any time, since you own it.
