Sharp little tools.

Four free apps for the Mac and Android, each built to do one job well: screenshots, downloads, file transfer and your clipboard. Made by one developer.

airshot freezes your screen when you press the shortcut, so you select from a still image. Mark it up, record a GIF or a video, copy text off the screen, and find any capture again in your history. Nothing leaves your Mac unless you upload it.

Built the way I'd want software built for me.

01

Your data stays yours

airshot keeps captures on your Mac. AirBridge sends files straight across your Wi-Fi, never through a server. Klipboard never saves your passwords.

02

One job each

Every app solves one problem from my own day, and lives where you already work: the menu bar, the share sheet, a keystroke.

03

Free

No trials, no accounts to make before you can try them. Download and use them.

Questions

Are the apps really free?
Yes. Every app is free to download and use, with no ads, no trial and no subscription.
Do I need an account?
No. There is no Kronyx account, and none of the apps ask you to sign in.
What do the apps send back?
No analytics and no automatic crash reports. The apps check dl.seqavo.com for new versions, and a bug report leaves your device only when you send one. Each app’s page lists exactly what it can access.
How do I install an app that isn’t from a store?
On a Mac, open the download, drag the app into Applications and open it. The first time, macOS blocks it: go to System Settings › Privacy & Security and click Open Anyway. On Android, open the APK and allow installs from your browser when asked.
When will the other apps be out?
Each one is released once it has held up in daily use. Its page offers a download the day it is ready.
I found a bug. Where do I report it?
Write to hello@kronyx.dev. Flume can also send a report itself, from Help › Report a Problem….
