What We Build

Apps for the way your business actually runs.

From back-office tools to customer-facing apps — we build for the Indian operating reality: spotty network, UPI payments, regional languages.

Business Apps
Internal apps for sales, ops, attendance, approvals — the daily software your team needs on their phones.
Field Staff Apps
For technicians, delivery, sales reps and supervisors on the move. GPS check-in, photo upload, offline-first.
Payment Apps
UPI, cards, EMI — Razorpay-backed payment flows with receipts, refunds and dispute handling baked in.
Customer-Facing Apps
Loyalty, bookings, orders, support — branded apps that put your business in your customer's pocket.
B2B Integrations
Apps that talk to ERP, accounting, GST, e-way bill, marketplaces and existing portals via secure REST APIs.
Manager Dashboards
Real-time KPI dashboards — revenue, attendance, stock, tickets — for owners and senior managers.
Technical Capabilities

A modern stack — battle-tested in production.

We build cross-platform first to keep your costs down, with native modules where it matters.

React Native & Flutter
Cross-platform — one codebase, Android and iOS. Native performance where you need it, faster delivery overall.
Node.js Backend
Production Node.js services with PostgreSQL or MongoDB, deployed on managed hosting with monitoring.
REST APIs
Versioned, documented REST APIs — easy to extend, easy to integrate with web portals and partners.
Firebase
Authentication, Crashlytics, Cloud Messaging and Analytics — for the parts where Firebase wins on speed.
Razorpay SDK
Native payment SDK with UPI intent, cards, netbanking, EMI and Razorpay X for payouts.
Push Notifications
FCM and APNs with topic, segment and per-user notifications. Delivery receipts and quiet-hours respected.
Offline Mode
Critical actions work offline — sync when network returns. Built for the Indian connectivity reality.
Biometric Auth
Fingerprint and Face ID for app unlock and high-value actions. Falls back to PIN gracefully.
Security

Secure by default — DPDP Act compliant.

Mobile apps handle login data, payments and personal information. We treat security as a first-class deliverable.

SSL / TLS Everywhere
All API calls over HTTPS with certificate pinning to block man-in-the-middle attacks.
JWT Authentication
Short-lived access tokens with refresh-token rotation. Stolen tokens stop working fast.
Encryption at Rest & in Transit
Database, file storage and on-device storage all encrypted. Keys rotated on schedule.
‍
Role-Based Access
Per-role permissions enforced both client-side and server-side. No hidden admin surfaces.
VAPT Before Release
Vulnerability Assessment and Penetration Testing on every major release, with findings tracked to closure.
No Third-Party Data Sharing
Your customer data is never sold or shared. Analytics scoped, ad SDKs avoided unless requested.
🇮🇳
DPDP Act Compliant
Consent-first flows, data principal rights, breach reporting — built to the letter of the DPDP Act 2023.
Audit Logs
Every privileged action logged with user, IP, device and timestamp — investigation-ready.
How We Deliver

From idea to live on stores — in weeks, not months.

A predictable, fixed-scope delivery process with checkpoints you control.

1
Requirements
A working session to lock the app's purpose, users, must-have screens and integrations. We send back a written scope.
2
Wireframes
Low-fidelity wireframes for every screen and flow. We iterate fast — usually 2–3 rounds, no scope creep.
3
Development
Sprints with weekly demos. You see the app on your own device every week, not at the end.
4
VAPT
Independent security review before launch. Findings tracked to closure with you copied.
5
Play Store / App Store Submission
We handle store listings, screenshots, privacy policies and the review back-and-forth. You go live.
6
Post-Launch Support
Crash monitoring, OS-version updates, store policy changes — covered for the first 90 days, optional retainer after.

Frequently Asked Questions

Everything you need to know about mobile app development with Digitruinx

Which is the best mobile app development company in India? +

Digitruinx is one of India's top AI-first mobile app development companies, specialising in building business apps for Indian SMEs. Every app we build comes with GST compliance, WhatsApp Business API integration, Razorpay payment support, and AI agent automation built in from day one. We handle everything from design to Google Play Store and Apple App Store submission — real deployments, not just prototypes.

How much does mobile app development cost in India? +

Mobile app development through Digitruinx costs from ₹75,000 for a simple single-platform app to ₹4,00,000+ for a full cross-platform app with backend, admin panel, payment gateway, WhatsApp integration, and AI agents. A standard business app for both Android and iOS using React Native typically costs ₹1,20,000 to ₹2,50,000 depending on features. All projects come with fixed pricing and a detailed scope document — no surprise billing.

Do you build both Android and iOS apps? +

Yes. Digitruinx builds apps for both Android and iOS using React Native and Flutter, which are cross-platform frameworks that allow a single codebase to run on both platforms. This reduces development cost by 40-60% compared to building separate native apps for each platform. Native development in Kotlin (Android) or Swift (iOS) is also available for apps requiring maximum platform-specific performance.

How long does it take to build a mobile app? +

A simple mobile app with 5-10 screens takes 4-6 weeks. A standard business app with login, database, backend API, and payment integration takes 8-12 weeks. A complex app with AI agents, multi-role access, WhatsApp automation, and an admin dashboard takes 12-20 weeks. Digitruinx follows a milestone-based delivery model — you get weekly progress updates, a test build for review at each milestone, and a final UAT phase before app store submission.

Can you integrate GST billing in a mobile app? +

Yes. Digitruinx integrates full GST billing directly into mobile apps — including invoice generation with HSN/SAC codes, IRN-authenticated e-Invoice generation via the NIC portal, GSTR-1 export, Razorpay payment link generation, and automatic payment reconciliation. Business owners can generate, send, and track GST invoices entirely from their mobile phone without needing a desktop computer or Tally software.

Do you submit apps to Play Store and App Store? +

Yes. Digitruinx handles the complete app store submission process for both Google Play Store and Apple App Store. This includes preparing all required assets (screenshots, app icon, store description, privacy policy), setting up or using your developer accounts, managing the review process, responding to any policy feedback, and getting the app approved and live. We also assist with post-launch version updates and Play Console/App Store Connect management.

What is React Native vs Flutter — which does Digitruinx use? +

React Native (by Meta) and Flutter (by Google) are both cross-platform mobile frameworks that build Android and iOS apps from one codebase, dramatically reducing cost and development time. React Native uses JavaScript and integrates well with existing web or Node.js codebases. Flutter uses Dart and produces apps with excellent UI performance and smooth animations. Digitruinx uses both: React Native for most business and IT portal apps, and Flutter for apps requiring high-performance UI or advanced animations.

Can you build a mobile app for my IT Portal? +

Yes. Digitruinx builds custom mobile apps that connect directly to the IT Portal SaaS via API. These include role-specific apps for field staff — teacher attendance apps for schools, delivery driver apps for logistics companies, service technician job card apps for automobile service centres, and site manager daily report apps for construction firms. All mobile apps sync in real time with the IT Portal, ensuring data is always consistent across web and mobile interfaces.
