Why teams choose dagtech
One team, end to end
Strategy, design, engineering and launch under one roof, so nothing gets lost between agencies.
We ship our own apps
Our team builds and maintains its own apps on the App Store. We know what it takes to launch and grow a product, not just deliver code.
AI-assisted, senior-reviewed
AI tooling speeds up the routine work; experienced engineers own the architecture, code review and quality.
Clear estimates, your code
A fixed estimate after a short discovery call. You own the source code and every account from day one.
How we work
- 01
Discovery
A short call to understand your goals, users and constraints. You get a clear scope, timeline and estimate.
- 02
Design
User flows and high-fidelity screens that follow Apple’s Human Interface Guidelines — reviewed together before a line of code.
- 03
Build
Iterative development in Swift and SwiftUI with regular TestFlight builds, so you can try the app on your own iPhone as it grows.
- 04
Launch
App Store assets, submission and review handled end to end. Your app goes live under your own developer account.
- 05
Support
Bug fixes, iOS version updates and new features after launch — based on real user feedback and analytics.
