Creating Free and Open Source Applications

Welcome to Dark Rock Studios. My mission is to create useful, high-quality software that's accessible to everyone. My apps are free and open source, and focus on privacy and offline first operation.

If that sounds good, I'd love your support!

Hammer

A simple tool for building stories.

hammer.ink

The Hammer Editor is a versatile and user-friendly tool for building stories, available across multiple platforms including phone, tablet, and desktop.
Designed for offline use, it stores your data in human-readable files, giving you full control over your content. Enjoy seamless, intelligent syncing between devices, allowing you to work on your stories from anywhere without concern for overwriting.
With adaptable light and dark modes and responsive design, Hammer ensures a comfortable and productive writing experience.

SnapSafe

Snap pics of anything, safely.

snapsafe.org

We capture photos locally, encrypt everything in private storage, let YOU decide if GPS tags are added, and strip out tell‑tale metadata automatically.

Fast Track

Track what your body is doing while fasting

Simple, Free, Open Source. No ads, no in-app purchases, no permissions. Just tell the app when you start your fast, and check back in to see what your body is doing during your fast.

Support FOSS Development

I think Free and Open Source development is an unalloyed good in the world.

It fills niches that commercial development can't justify, and helps people who can't now, or maybe ever, pay for the software they want or need.
It provides auditable code to protect privacy and security in a world increasingly dominated by bad faith corporate interests.
The code it's self can serve as a springboard for new developers who can dive in and learn how an interesting thing is done, and become better developers for it.
I make free end-user applications, as well as permissively licensed libraries for the wider developer ecosystem. If you believe as I do that Open Source software is an important good in the world, then I'd love your support.

Open Source Libraries

Compose Text Editor

Compose has been missing a Rich Text Editor since its inception. This library attempts to fill the gap. It handles large documents and fully flexible rich text.
The flexibility afforded by it has been used to implement a fully cross-platform Spell Checking solution. The first of it's kind in the Kotlin/Multiplatform world.

MIT
SymSpellKt

A Kotlin/Multiplatform port of the SymSpell algorithm. Designed for performance, it brings edit-distance-based spell checking to any Kotlin target.

MIT
FDic

A binary file format for frequency dictionary libraries. It is both 40% smaller on disk, and 70% faster to load and parse than text-based frequency dictionaries.
A native CLI program is provided to encode frequency dictionaries into the .fdic format.

MIT
Godot Opus

Opus is an industry standard library for compressing real-time audio for VOIP applications. Godot Opus is a library implementing Opus in an easy to consume library for Godot 3.x games to implement voice chat.

MIT
LAN Server Broadcast

A simple Godot 3.x library enabling peer-to-peer server browsers in Godot games. No match-making server required, great for LAN games.
