How We Build Your App
— From Idea to App Store

A clear 5-phase process — you see progress at every stage and nothing goes into development without your approval first.

Discovery & Planning

Free consultation — we map your app idea, define features, choose the right platform (Android/iOS/both) and create a project plan.

2

UI/UX Design

Wireframes then full app screens designed and shared for your review. Development starts only after your design approval.

3

Development

Frontend app + backend API built in sprints. Regular builds shared for your review throughout development — no black box.

4

Testing & QA

Tested on real devices — functionality, performance, security, edge cases and user acceptance testing before submission.

5

Launch & Support

App Store & Play Store submission handled. Training provided. Source code & all assets delivered. Post-launch support included.

FAQ

Frequently Asked Questions
About Mobile App Development

How much does it cost to build a mobile app?
App cost depends on complexity, features and platforms. A basic single-platform app starts from $599. A full-featured Android + iOS business app typically costs $1,299-$2,500. Complex on-demand apps (like Uber or food delivery) with multiple user types are custom quoted. We provide a detailed cost breakdown after a free consultation where we understand your full requirements.
Should I build for Android, iOS or both?
For US businesses — iOS first, as iPhone users in the USA tend to have higher spending power. For India/global — Android first, as it has 73% market share. For most businesses, we recommend both platforms using cross-platform development (React Native or Flutter) to save cost while covering all users. We’ll advise the best approach based on your target market during consultation.
How long does it take to build an app?
A simple app (5-8 screens) takes 30-45 days. A medium business app (15-25 screens with backend) takes 60-90 days. Complex apps with multiple user types (like food delivery or on-demand services) take 90-150 days. We work in sprints and share regular progress — so you always know exactly where your app stands.
Do I get the source code?
Yes — 100%. After final payment, you receive complete source code for the app AND backend, along with all design files, database structure and documentation. Everything is yours. You’re never locked into our services — you can hire any other developer in the future if you choose to.
Do you handle App Store and Play Store submission?
Yes — we handle the entire submission process. This includes preparing screenshots, writing app descriptions, setting up app categories, submitting for review and responding to any rejection feedback from Apple or Google. You’ll need a developer account (Apple Developer: $99/year, Google Play: one-time $25) — we’ll guide you through setting these up.
Can you build apps for businesses in the USA and UK?
Absolutely. We work with clients in USA, UK, Canada, Australia, UAE and 200+ countries. All communication is in English, we work across time zones, and accept secure payments via PayPal in USD, GBP, EUR, CAD and AUD. Your app can target any market worldwide and will be optimized for your target audience.
What happens after the app is launched?
All projects include post-launch support (30-90 days based on project size) for bug fixes, small adjustments and help with App Store issues. After this period, we offer ongoing maintenance plans for regular updates, new features, OS compatibility updates and security patches. We’re always reachable via WhatsApp for urgent issues.
