Native Apps
iOS and macOS apps built in SwiftUI with the care of a first-party product: offline-first data, App Store polish, and native performance from the menu bar to the pocket.
Independent software studio Building software
Building software
that ships.
NᵗʰCube designs and builds apps for iOS, macOS, and the web, from the first sketch to the App Store. Considered, fast, and privacy-first by default.
Now building
A small studio that builds
across the whole stack.
We don’t hand off between teams. The same people who design the interface write the code and ship the release, which is why the details hold together.
Web & Cloud
Fast, resilient web apps on Cloudflare’s edge: Workers, D1, and R2. No servers to babysit, privacy-first by default, and latency measured from the nearest city, not a distant datacenter.
Product & Craft
We take an idea from the first sketch to a shipped release: interface design, engineering, and the thousand small details that decide whether people keep an app or delete it.
What we’re building right now.
4 products in active development across iOS, macOS, and the web. Each one is our own, designed and engineered end to end.
wherewasi
Web appTurn a pile of photos into a map of where you have been.
Drop in your photos and wherewasi reads their GPS and timestamps in the browser, groups them into the places you actually stopped, names each one, and lays the trip out as a timeline beside a map. Your trips follow you between devices, and every photo is encrypted on your own machine before it is uploaded.

Battery Watcher
macOSNever get caught at one percent.

The studio A studio, not a
A studio, not a
software factory.
NᵗʰCube is a small, independent software company. We work on a handful of things at a time and give each the attention it needs. That is the kind of care that only shows up when the people designing a product are the ones building it.
Fifteen years of shipping has taught us that the details are the product. We sweat the empty states, the offline case, and the millisecond of latency, because that’s what people actually feel.

Before you write in.
The things people usually want to know. If yours is not here, ask us directly.
How is NthCube pronounced?
"Enth Cube", as in the nth term of a sequence. It is written NᵗʰCube, with a superscript "th", and spelled NthCube anywhere a superscript will not travel.
What does NthCube build?
Native apps for iOS and macOS in SwiftUI, and web applications that run on Cloudflare’s edge with Workers, D1, and R2. We currently have four products in active development across those three platforms.
Do you take on new projects?
Yes. We are available for new projects and reply to every message ourselves. Email contact@nthcube.com and tell us what you have in mind, even if it is still only an idea that needs a second opinion.
Do you handle design as well as engineering?
Both, under one roof. The same people who design the interface write the code and ship the release, which is why the details hold together instead of getting lost in a handoff between teams.
What does privacy-first actually mean here?
It means your data moves as little as it can, and never in the clear. Battery Watcher has no account, no network calls, and no analytics at all. wherewasi encrypts every photo in your browser before it is uploaded, and its advanced mode puts the key behind a passphrase we do not hold, so we could not read your library if we were asked to.
How big is the studio?
Small and independent by design. We work on a handful of things at a time and give each the attention it needs, which is the kind of care that only shows up when the people designing a product are the ones building it.
