rollando.dev — web & software development
I’m Roland Matuz, a developer based in St. Gallen. I build web applications, desktop tools, and websites with clear interfaces and maintainable code. Explore the projects below to see how they work.
What we do
Websites, browser tools, desktop apps and plugins — designed and engineered end to end, in English and German, with the same attention to detail.
04
Native apps for Mac and Windows. Private, offline, on your own device.
03
Portfolios, editorial sites and link hubs. Bilingual, fast, built to be read.

Calm PDF reader & annotator for Mac & Windows
A calm, distraction-free PDF app for study and work. Highlight, draw and write on any page, turn passages into numbered citations with footnotes, and keep it all as editable annotations inside the PDF itself. Offline, no account, no cloud.
Reading on a screen asks for a kind of attention that the screen itself keeps interrupting. Notifications, toolbars and badges all compete for the same narrow channel.
A good reading tool therefore does less, not more: it steps back until you need it, and then gets out of the way again.
Marking a passage is a way of thinking with the text. The margin is where reading turns into writing.
When we cite, we make that conversation public: we show where an idea came from and invite the reader to follow it back to its source.
11 Good framing for the introduction; compare chapter 3.
On-device speech transcription for Mac and Windows
Turn calls, videos, podcasts, and voice notes into text. Speech recognition runs locally, with an interface for reviewing and saving transcripts.
Okay, let's get started. Thanks everyone for joining the weekly sync.
First up, the launch checklist. The website copy is done and the download page is live.
We still need final screenshots for the press kit, ideally in both light and dark mode.
Can we have those by Thursday? Then marketing has a day to review them.
Great. Next topic: the customer interviews from last week.
YouTube downloads and local media conversion
Download video or audio from a link, or convert media files on your computer. Guppy brings these tasks together in a desktop interface for Mac and Windows.
Fluid Mac cleaner and system space optimizer
Reclaim storage from hidden system caches, developer artifacts, and Time Machine APFS snapshots. Free and open source with a fluid liquid glass interface.
Source code Mac
Analyze system junk, developer artifacts, and reclaim disk space
Application cache files safely rebuilt by macOS on demand
Mail downloads, iOS firmware IPSW, incomplete downloads, & system media caches
Xcode DerivedData, CocoaPods, npm, and Homebrew caches
Diagnostic reports, crash logs, and system logging buffers
Cached web assets from Safari, Chrome, and browsers
Items sitting in user and external volume trash cans
Pinch-to-zoom plugin for Obsidian
An open-source Obsidian plugin that adds pinch-to-zoom to notes on touchscreens and trackpads — in reading and editing view. Text and images grow and rewrap to the pane like browser zoom, or magnify like a PDF. Each pane keeps its own zoom.
Personal website and professional background
A personal website bringing together my work, experience, and contact information, with light and dark themes and English and German content.
One place for profiles, projects, and links
A compact link page for my professional and creative profiles. Designed for quick navigation on phones and desktop screens.
A portfolio of photography and architecture
A photography portfolio presenting selected images and series. The layout gives photographs room and keeps navigation simple.
Typing practice with live feedback
Practice typing with timed exercises, word-count sessions, and a visual keyboard. Track speed and accuracy as you type.
