Hey Product Hunt 👋 I built Calendar DND because I kept having the same embarrassing moment. Phone buzzes in the middle of a call, I scramble to silence it, everyone notices. The fix felt obvious: my phone already knows I'm in a meeting. It has my calendar. Why doesn't it just go quiet on its own? So I built that. Calendar DND reads your calendar and automatically activates Do Not Disturb when a meeting starts. When the meeting ends, your sound comes back. That's the whole thing. A few things I'm particularly happy with: - Smart merging: back-to-back meetings stay silent without a gap between them - Respects you: if you manually change DND mid-meeting, the app backs off - Privacy first: everything runs on-device, no accounts, no cloud - Open source (Apache 2.0), every line is on GitHub Free on the Play Store, Android 8.0+. Happy to answer questions or debug edge cases with your calendar setup, just drop a comment. - GitHub: https://github.com/BrunoAFK/Cale... - Play Store: https://play.google.com/store/ap...
