Direct Developer Access
You communicate directly with the engineer writing your application. No project managers, sales translation errors, or bureaucratic delays.
Milestone-Based Billing
Payments are tied strictly to delivered, testable stages. You review working software before releasing milestone payments.
Runnable Test Builds
Regular APK and test builds throughout the sprint so you can touch, test, and experience features on real devices as they are completed.
Store Submission Support
Guidance preparing Google Play Store and Apple App Store compliance assets, privacy policy declarations, and release configurations.
14 Factors That Drive Mobile App Costs
Understanding what drives development effort helps you optimize your requirements and prioritize your budget effectively.
1. Number of Screens
A 4-screen MVP requires far less architectural and layout effort than an 18-screen platform with multiple nested subflows.
2. UI/UX Fidelity
Standard Material & Cupertino components are faster to implement than bespoke micro-interactions and complex custom animations.
3. Platform Scope
Flutter enables 35–45% cost savings by compiling to both Android and iOS from a single codebase compared to two separate native teams.
4. Backend & Database
Connecting to an existing REST API is faster than designing greenfield PostgreSQL schemas, serverless logic, or auth roles.
5. Authentication & Roles
Email/password, OTP/SMS phone verification, Google/Apple social logins, and multi-tenant user permission hierarchies.
6. Payment Gateways
Razorpay, Stripe, or Apple/Google In-App Purchases (IAP) requiring server-side receipt validation and webhook reconciliation.
7. Push Notifications
FCM (Firebase Cloud Messaging) and APNs for automated order updates, transactional reminders, and user re-engagement.
8. Web Admin Portal
A web-based dashboard allowing business owners to manage products, view customer orders, and control app content dynamically.
9. Third-Party Integrations
Connecting with external APIs such as CRMs, ERPs, SMS gateways, analytics suites, or logistics tracking webhooks.
10. Maps & Geolocation
GPS tracking, reverse geocoding, interactive Google Maps/Mapbox overlays, and polyline distance calculation.
11. Realtime & Chat
One-on-one or group messaging, WebSockets, presence detection, and instant unread badge synchronization.
12. Offline-First Caching
Local SQLite/Hive persistence allowing users to browse, create drafts, and perform actions without an active internet connection.
13. Store Policy & QA
Google Play closed testing (20 testers for 14 days), iOS App Store human review compliance, and physical multi-device QA.
14. Ongoing Maintenance
Periodic Android target SDK updates, iOS OS compatibility updates, dependency maintenance, and bug fixes.

Frequently Asked Questions About App Costs
An initial quotation and technical feasibility review is completely free. Once you share your requirements, I review the scope, suggest technical recommendations, and provide a transparent, milestone-based quotation with no obligation.
No! Because I specialize in Flutter, we build a single, natively compiled codebase that runs smoothly on both Android and iOS. This typically saves 35% to 45% compared to hiring two separate native development teams (Swift and Kotlin).
The development and integration of the backend (such as Firebase, Supabase, or a custom REST API) are included in the development milestones. Ongoing cloud infrastructure hosting costs (Google Cloud, AWS, Supabase tier) are paid directly by you to the provider, ensuring you own your data accounts.
Both options are supported. If you already have Figma designs, I implement them pixel-perfectly in Flutter. If you don't have designs yet, I can design intuitive, modern layouts adhering to Apple Human Interface and Google Material Design guidelines as part of the project.
Payments are broken into transparent phases (typically: deposit on agreement, core architecture demo, complete feature demo on device, and final store deployment/code handover). You review verifiable software at each step before releasing the next payment.
Timelines depend strictly on feature complexity and scope. A lean startup MVP or utility app typically progresses through milestones over 4 to 8 weeks, whereas complex marketplace platforms with custom backends and admin portals take longer. Exact milestone dates are agreed upon in your quote.
Yes, this is the recommended approach for most founders. Starting with a focused MVP validates your market with real users at a lower initial cost. The codebase is built modularly from day one so future features can be integrated seamlessly.
You do. All intellectual property, source code, designs, and deployment credentials are 100% owned by you. Full Git repositories are transferred to your accounts upon completion.
