App development in Bengaluru and Kochi.

We design, build and launch mobile and web apps for startups and established businesses, using the same process and technology we use for our own products, GameHarbor and MindHarbor. You get one team for product strategy, UI/UX, development, store release and the marketing that follows.

Signs it is time.

You have validated demand and need a product people can install, you are replacing a fragile app built by a freelancer, or you need an internal tool your team will actually use.

What is included

Scope, in plain words.

01

Product discovery

User journeys, feature priorities and a scoped MVP with a fixed budget range.

02

Cross-platform apps

Flutter or React Native for one codebase on Android and iOS when that fits.

03

Native and game builds

Kotlin, Swift and Unity where performance or platform features demand it.

04

Web apps and PWAs

Installable web apps for audiences on low-end phones or limited data.

Questions

App development: common questions.

How much does an app cost in India?

It depends on scope: number of screens, user roles, integrations, offline needs and whether you need an admin panel. We quote after a discovery call with a written scope, timeline and cost. Our guide to app development costs explains the main cost drivers.

Do I own the code?

Yes. Code lives in a repository you own from day one, and store accounts are registered in your company name.

Have you shipped apps of your own?

Yes. Old Port publishes GameHarbor, a wellbeing arcade with an AI companion, and MindHarbor, an open-world wellness game, and is building ZEVORA, a cozy open-world mobile game.
