  • Native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose)
  • Cross-platform with React Native and Flutter
  • Offline-first data sync and background jobs
  • Push notifications, in-app messaging and deep linking
  • App Store and Play Store publishing, plus CI/CD for weekly releases

Testimonials

What our clients say

Long-term partnerships built on measurable outcomes, honest communication and code we're proud to ship.

Extko rebuilt our fee reconciliation module in eight weeks. What used to take our office three days now takes three clicks. Their team genuinely understands how schools operate.

Ananya Rao
Director, Everbright Schools

The AI-powered lead scoring model Extko delivered doubled our sales team's efficiency in one quarter. They shipped on time, on scope, and stayed for the post-launch support that actually matters.

Vikram Menon
CTO, Atlas Pay

We evaluated four vendors for our ERP migration. Extko was the only team that mapped our workflow before pitching a solution. Six months in, adoption is at 94% across three plants.

Priya Shankar
Head of Operations, Orbit Logistics

A design partner and an engineering partner in one team. Our mobile app launch hit 50,000 downloads in the first month with a 4.8 rating. That's Extko's craftsmanship.
