Indie iOS app studio
Small apps that do
one thing perfectly.
noshu is a two-track studio. We build a growing shelf of small, focused iOS apps of our own — and we build custom apps for clients who want the same care.

A few we’re proudest of.
The lead is the one we’d hand you first. The rest are ordered by what’s actually selling and getting downloaded. Same idea every time: pick one honest problem, then solve it beautifully.
On the App Store
Live on the App Store.
Every one does a single job, works offline, and is paid for once. No ads, no subscriptions, no accounts, nothing phoning home.

How we build
The same four rules, in every app we ship.
One job, done properly
Every app has a single, sharp purpose — no feature bloat, no dashboard you'll never open. It does its one thing and gets out of your way.
Private by default
No accounts, no analytics, no tracking. Almost everything runs on-device and works fully offline. Your data stays on your phone.
Pay once, keep it
Most are a one-time purchase; a few are free. None of them will ever nag you to subscribe or gate the app you already bought.
Native and fast
Built in Swift for iOS, so each app feels like it belongs on the phone — quick to open, quick to use, quick to put down.
Work with us
Need something quick, simple,
and to the point?
If you’ve got one clear idea — a tool, a tracker, a calculator, the kind of small app that should just exist — we’ll design it, build it, and ship it to the App Store. Native, no bloat, no drawn-out agency process. Tell us what it needs to do; we’ll tell you what it takes and what it costs. Usually less than you’d expect.
Fast, not sloppy
Modern tooling lets us build in days what used to take months — without shipping something half-baked.
One flat price, up front
Agreed before we start. No retainer, no surprises. Small scope keeps it a fraction of agency rates.
Genuinely native
Real SwiftUI that feels at home on iOS — not a web page in a wrapper.
Yours, and shipped
We take it all the way to the App Store and hand over the finished app. No loose ends.
