Download

Every download is built automatically from Daylo's public code. Nothing hidden.

Windows Windows 10 or later. The Store installs it without any warning.
Mac Mac may ask you to allow it in Privacy and Security.
Linux Works on most Linux systems.
Android Phones and tablets from 2017 onward. Allow installs from this source when asked; when Play Protect blocks it, tap the small Install anyway link.

Daylo is new, so Mac and Android will most likely show a warning the first time you install it, and so will the Windows installer. That is normal for apps not yet registered with Apple or Google. On Mac, allow it in Privacy and Security. On Android, Play Protect blocks the install with a big Got it button: the small Install anyway link below it is the one that continues. On Windows, the Microsoft Store version has none of this; if you use the installer instead, click More info and then Run anyway. Every release includes a list of file checksums if you want to double-check a download.
