Independent software studio for macOS

Mac apps that feel at home on your Mac.

VolMa builds focused, native software for macOS. Our apps do one job well, run on your own hardware and keep your data where it belongs — with you.

Our apps

OnFly

macOS 15 or later · Apple silicon and Intel

Torrent video that starts playing before the download ends.

Open a .torrent file or magnet link and press play. OnFly fetches exactly the pieces the player needs, keeps disk use inside a fixed budget and remembers where you stopped.

Guardly

macOS 12 or later · Apple silicon · In development

Home video surveillance that never leaves your Mac.

Guardly will let you connect your IP cameras, record motion events locally and check on home from any browser — no cloud account, no subscription, no one else holding your footage.

How we build

Four rules every VolMa app follows.

  • Native first

    Real Mac controls, keyboard shortcuts, Light and Dark appearance and accessibility labels — built with SwiftUI and AppKit, never a web page in a wrapper.

  • Local by design

    Your media, recordings and history stay on your Mac. No accounts, no analytics, no cloud service sitting between you and your data.

  • Light on resources

    Hardware video decoding, bounded disk caches and careful memory use, so our apps stay quiet in the background and fast on battery.

  • Fair licensing

    Pay once per license, activate on your Mac and keep working offline. Open-source components are credited and their sources published.

About VolMa

A small studio with a narrow focus: the Mac.

VolMa is an independent developer of macOS software. We don’t build for every platform at once — we build for one, and we build it properly: Swift and SwiftUI where they shine, AppKit where precision matters, and Apple’s own frameworks for video, networking and security instead of heavy third-party stacks.

Each app is signed, notarized and distributed directly by us. You buy a license once, activate it on your Mac, and keep working even when you’re offline.
