TIP JAR — THE APPS STAY FREE EITHER WAY

PRICE0.00 €

ACCOUNTnot needed

Every app here is free — no ads, no tracking, no accounts, no upsell. If one of them saved you time and you feel like it, you can drop a tip. Entirely optional, and the apps stay exactly the same either way.

Not into tipping? Just as welcome: tell a friend or star a repo on GitHub.

01 Where it goes

Hosting & signing

Webspace, the Apple Developer account, and notarization so every app installs cleanly and updates over Sparkle.

New apps & updates

Time to keep the existing apps current with each macOS release — and to build the next ones.

Never paywalls

Tips don't unlock anything. There's no Pro tier hiding behind this — the free apps are the whole deal.

02 Good to know

No pressure

The apps are free whether or not you ever land on this page. This is a tip jar, not a checkout.

Your privacy

Tipping happens entirely on Ko-fi. This site sends nothing anywhere — no analytics, no accounts.

Thank you

Genuinely. Even a coffee's worth of support means a lot to a one-person studio.
