Independent app studio · iOS · Android
ByteHaven Studios is an independent app studio. We design, build, and ship our own native iOS and Android apps — and the backends behind them — then stay on to maintain and grow each one. Private by default: no ads, no tracking, no dark patterns. Finished, not just shipped.
Craft
Four things every ByteHaven app is made of. Each line below is in an app you can download today, not a capability we are advertising.
Native iPhone and iPad apps in Swift and SwiftUI. TuneHaven is the one on the App Store: a SwiftUI interface over a shared Kotlin core, with a home-screen widget, Live Activities while you practise, and StoreKit purchases.
Native Kotlin and Jetpack Compose, with a shared multiplatform core when it earns its keep. BootForge is native Android talking to real USB hardware; TuneHaven runs one Kotlin core on both phones. Built for the real spread of devices, not just the demo phone.
The parts an app needs to be real, built alongside it rather than as a separate project. Ours are all in production: the image catalogue BootForge downloads from, the CDN and signed update feed behind the Mac build, and the feedback intake this very site runs on.
Most studios disappear at launch. We stay: OS updates, crash triage, performance work, and the features that turn a v1 into something people keep on their home screen. The Mac build carries its own signed update feed with incremental patches, so an install that has been sitting for months catches up by itself.
Apps
A native Android app for building Ventoy multiboot USB drives over USB OTG — rescue systems, installers, and disk tools on one drive. Private by default: no ads, no accounts, no tracking.
iPhone version still in the workshop.
bootforge.bytehavenstudios.com →A tuner for guitar, bass, ukulele, violin and 14 more instruments, plus voice — with courses, a chord library and a practice toolkit around it. It asserts nothing it can't actually know: no early green, and it never switches strings behind your back. Fully offline, no ads, no account.
A short, deliberate lineup — each app fully finished before the next, never a pile of half-built ones. Neither of these is on a store yet, and we say so here until a listing is genuinely public.
An offline income, mileage and expense ledger for mobile notaries and loan-signing agents: every signing, every mile, and Schedule C-ready exports when tax time arrives. Android and iPhone, and it asks for no permissions at all.
Built and tested · not submitted yet

Process
Every app starts by pulling the idea apart — what's the smallest version that proves it works, and what's genuinely hard.
Short cycles, working builds on real hardware early via TestFlight and Play tracks — tested across the actual spread of phones, not just the one on the desk.
Review submissions, signing, store listings, release management — the unglamorous half of shipping, and the half that decides whether launch day is uneventful.
After launch we keep the app current and the roadmap moving. The same person who built it is the one improving it.
Principles
We ship fewer things, fully finished. A release waits until it is.
No ads, no nags, no dark patterns. Private by default.
We say what's done, what isn't, and what it costs. No launch-day overclaim, no roadmap we can't keep.
Clean foundations and restraint with fads. We build things meant to age well, not just to demo.
The person who builds the app is the one who answers your email.
Built to keep.
Questions
Native iOS and Android apps — utilities and tools built to do a real job well. Each one is private by default, works offline where it can, and is made to keep rather than to chase a trend.
Honestly — and never by selling your data or your attention. There are no ads and no tracking, full stop. Where an app is paid, it's a straightforward price on the store, and in return you get software that keeps working for you.
Our focus is our own apps, so we're not a general dev shop. If you're building something that's genuinely a fit for how we work, say hello — but no promises, and no sales pipeline.
Depends on the app. We build native for each platform rather than cutting cross-platform corners where they'd cost quality, and each app ships where it makes sense — sometimes one platform first, then the other.
That's the whole point. We stay on after release — OS updates, fixes, performance work, and the steady stream of features that turn a v1 into something worth keeping on your home screen. Same people, start to finish.
