Custom Mobile App Development Company in Sri Lanka
BATSTACK builds Flutter, React Native, and native Android/iOS apps for Sri Lankan businesses and startups — with PayHere and local gateway integration, offline-first sync for unreliable networks, and bilingual Sinhala/English interfaces. A one-time build you own outright, backed by a local team in Gampaha.
Why Sri Lankan businesses build with BATSTACK
You own it — no foreign rent
A one-time custom build you own, instead of bleeding USD subscriptions to an overseas app platform every month.
Local support that answers
A Sri Lankan team in Gampaha — reach us in Sinhala or English on WhatsApp, not an overseas ticket queue.
Built for local payments
PayHere, DirectPay, Genie, and bank IPG integration so your app collects card and mobile payments the way Sri Lankans pay.
Offline-first for real networks
Your app keeps working when the connection drops and syncs automatically when it returns — no lost data on the road.
International-grade engineering
The same Flutter / React Native stack we ship to overseas clients — clean, tested, and store-ready — at Sri Lankan pricing.
The full engineering stack — mobile to cloud
Cross-Platform Excellence
Flutter and React Native for one maintainable codebase across Android and iOS — faster to ship, cheaper to maintain.
Native Mobile
Native Android (Kotlin) and iOS (Swift) when you need platform-perfect performance and deep hardware access.
Local Payments & APIs
PayHere, DirectPay, Genie, and bank IPG integration, plus Node.js/Go + PostgreSQL backends for real-time sync and offline-first data.
Bilingual & Cloud-Hosted
Sinhala/English interfaces, cloud hosting with backups, and CI/CD — encrypted in transit and at rest.
A transparent 4-phase delivery framework
Discovery
A 30-minute technical discovery call becomes a costed scope — user flows, architecture, tech-stack decisions, and a fixed sprint plan. You leave knowing exactly what, when, and how much.
Interactive Prototype
A clickable, real-data prototype before full engineering begins — so you validate the product and align stakeholders before the expensive part starts.
Agile Sprint Engineering
Weekly sprints, demoed live. Every sprint ships working software to a staging build you can install, with full Git + Jira transparency throughout.
Deployment & SLA Support
Store submission, production launch on AWS/Cloudflare, monitoring, and a defined post-launch SLA for maintenance, updates, and scaling.

Frequently asked questions
How much does mobile app development cost in Sri Lanka?
BATSTACK builds custom apps as a one-time investment scoped to your features, not a recurring foreign subscription. After a free requirements call you get a fixed LKR quote, and you own the source code and app outright.
Can you integrate PayHere and local payment gateways?
Yes. We integrate PayHere, DirectPay, Genie, and bank IPGs so your app accepts card and mobile-wallet payments with settlement to your local bank account.
Will the app work with poor or no internet?
Yes. We build offline-first: the app keeps working without a connection and syncs automatically when it returns — important for delivery, field sales, and rural users.
Do you build apps in both Sinhala and English?
Yes. We build bilingual Sinhala/English interfaces so every user is comfortable, with the option to add Tamil on request.
Do you provide support after the app launches?
Yes. As a Gampaha-based Sri Lankan studio we provide bilingual support and a defined SLA covering updates, OS-version maintenance, and fixes — with a local team that responds.
