Clock Informer has been a personal passion project since 2019. Everything here — the firmware, over-the-air updates, and these 3D-printable cases — is free to use, and always will be.

I build and improve it in my spare time, just because I enjoy it. If it found a place on your desk and you'd like to support its continued development, you can buy me a coffee here:

No pressure at all — a like, a comment, or a photo of your build makes my day just as much. Thanks for being part of this! 🙂
