One developer. Four apps. Zero investors.
MrNick Apps is Niklas Nilsson, working solo out of southern Sweden. Every app in the catalog is designed, coded, shipped and supported by the same person — no team, no ad networks, no analytics that sell your data.
The apps share a philosophy more than a look: track your own thing carefully, keep the data yours, and stay out of your way the rest of the time.
How these apps are built
- // no-ads
None of the apps show ads. Ever. If an app has a Pro tier, that's the only way it earns.
- // privacy-first
Data stays on your device or in your own account. Nothing is sold, shared, or handed to advertisers.
- // focused
Each app does one job and does it clearly. No feature-creep, no bundled services.
- // personal
Every app in the catalog is one I use myself. If it wouldn't survive on my own home screen, it wouldn't ship.
Feedback, bugs, ideas — all welcome.
The fastest way to reach me is email. I answer everything, though sometimes not on the same day (solo dev, remember).
