App Development & Publishing

We turn app ideas into apps people actually use.

Sevenko Apps is the Auckland studio that designs, builds and publishes mobile apps for iOS and Android — from first sketch to live on the stores, and beyond. No hand-offs, no guesswork. One team takes your idea all the way to a shipped, growing product.

What we do

Full-cycle app development. One partner, the whole journey.

We don't hand you a spec and disappear. One in-house team carries your app from idea to launch to growth, so nothing gets lost in translation.
