Independent mobile product studio

We build mobile apps worth keeping.

Indus Apps is an independent studio that designs, builds and ships its own products for iOS and Android — one carefully crafted app at a time.

The studio

We don't take client work. We build our own products — designed end to end, held to a single standard, and made to last on the one device people never put down.

Independent

Our roadmap is ours. No outsourcing, no compromises.

Product-led

We design for real behaviour, then refine until it feels effortless.

Built to last

Fewer apps, made properly — and maintained for the long run.

Our apps

A small, growing
family of products.

Each app is its own product with its own home. This is where the family begins.

How we build

Craft over quantity.

01

Mobile-first

Designed for the phone first — the device people actually reach for, not a scaled-down desktop.

02

Owned end to end

Idea, design, code and roadmap under one roof. That ownership is what holds the bar.

03

Quietly powerful

Deep capability with a calm surface. Polish isn't decoration — it's the experience.

04

Made to last

A shared foundation and clear standards keep every app consistent, and maintained for years.

Our vision

A studio behind a family of mobile products people are glad to keep — each one useful, elegant and quietly indispensable.

We're building that family patiently, across the categories people live in every day. CalcOS is chapter one.
