How we work: Agile methodology & sprint framework
We eliminate the risks of traditional waterfall agency contracts by building your product in rapid, transparent 2-week agile sprints. You get continuous visibility, weekly staging demos, and the flexibility to adapt priorities as your vision evolves.
2-Week Sprint Cadence
Work is broken into predictable 14-day sprint cycles with defined story points, clear acceptance criteria, and transparent milestone commitments.
Free First Wireframe (Sprint 0)
We de-risk your investment by delivering your initial wireframe and architecture roadmap for free before any long-term contract is signed.
Live Staging & Weekly Demos
You test real, working software every week on a private staging link. No static slide decks — see actual progress in real time.
Adaptive Scope Flexibility
Market conditions change. Re-prioritize your product backlog at the start of any sprint without painful change orders or penalties.
Direct Engineer Access
Collaborate directly with your dedicated Scrum Master and engineers in a shared Slack or Teams channel. Zero middlemen, zero miscommunication.
100% Code & IP Ownership
Every commit belongs to you. Complete Git repository, documentation, deployment scripts, and credentials handed over at milestone completion.
The 14-Day Sprint Lifecycle
1. Sprint Planning
User stories groomed, acceptance criteria locked, story point commitments agreed.
2. Focused Build
Daily async standups, test-driven code execution, continuous integration to dev branches.
3. Demo & QA
Live walkthrough on private staging URL, client feedback incorporated directly.
4. Release & Retro
Milestone pushed to staging/production, sprint retrospective held, next sprint planned.

How much does it cost to make an app in India?
Mobile app development cost in India depends mainly on the number of screens and features, whether you need iOS, Android or both, and how much backend work is involved — for example payments, real-time tracking or an admin panel.
We scope a focused MVP first so you can launch, learn from real users and invest further with evidence. You receive an itemised, milestone-based proposal after a free consultation. Many MVPs launch in 8–12 weeks.
Key factors that affect investment
- ✓iOS, Android or both (native vs cross-platform)
- ✓Number of screens and user roles
- ✓Backend, APIs and admin panel
- ✓Payments, maps, chat or real-time features
- ✓Third-party integrations
- ✓Post-launch maintenance

Frequently asked questions
Everything you need to know about our sprints, timeline, code handoff, and support.
[01]How much does mobile app development cost in India?+
It depends on features, platforms and backend work. We send a fixed, itemised proposal after a free consultation, and usually recommend starting with a focused MVP to control cost.
[02]Should I build with Flutter or React Native?+
Both are excellent cross-platform choices. React Native suits teams already using React on the web; Flutter is strong for highly custom interfaces. We recommend one based on your product and team.
[03]How long does it take to develop a mobile app?+
A focused MVP typically takes 8–12 weeks. Larger apps with multiple user roles, payments and real-time features are delivered in phases.
[04]Do you build both the app and the backend?+
Yes. We build the APIs, database and admin panel alongside the app so you can manage users, content and orders from day one.
[05]Do you publish the app to the App Store and Google Play?+
Yes. We prepare listings, screenshots and privacy disclosures, submit the builds and handle any review feedback from Apple or Google.
[06]Can you take over an existing app?+
Yes. We start with a code audit, fix critical issues, then continue development or plan a rebuild if the existing codebase is holding you back.
