About
Hello, I'm Karl.
I build useful apps, plugins, extensions, and tools for real work. I care about clarity, privacy, and software that feels good to use.
Why I'm doing this
Too many useful tools come with too much junk.
I got tired of software that wrapped simple jobs in tracking, bloated permissions, upsells, and friction. I would rather build tools that feel clear, useful, and respectful the first time you open them.
Stealthy Apps is where I ship that work. FillPro is the first public release, but the goal is bigger than one extension. I want this to be a home for practical software people trust and keep around.
How I work
What I want Stealthy Apps to stand for.
Real free tier
Free should stand on its own. Paid upgrades are there for extra room, advanced features, or people who want to support the work, while the core product stays useful on day one.
Fair pricing
I price products around the time and frustration they save. If something is paid, the value should be easy to understand and the pricing should feel fair.
No ads. No junk installs.
I am not building Stealthy Apps around ads, bundled installs, or dark patterns. I would rather keep the products straightforward, useful, and easy to trust.
