A Callendar-ról
We believe meetings shouldn't slip through the cracks. Callendar turns every meeting into an incoming call — the only reminder your brain still respects.
Küldetésünk
Callendar was built because silent notifications get dismissed in a glance and calendars are on mute. Founded in 2024, we're a small team of engineers and designers obsessed with the question: why is a text message a push notification, but a scheduled meeting is too?
Whether you're running back-to-back calls, working in Focus mode, or just have your phone face-down — Callendar rings your phone like a real call so you never miss a standup, 1:1, or board update again.

Értékeink
Reliability
A meeting reminder that fails is worthless. We obsess over VoIP push, background execution, and edge cases so the ring always comes through.
Privacy First
We read your calendar read-only to schedule rings. Your events are never sold, shared, or used to train AI models.
Respect for Focus
We only break through silent mode because the meeting warrants it. Quiet hours and per-calendar overrides keep you in control.
Globális távoli csapat
Callendar is built by a fully remote team of mobile engineers, product designers, and operators who have lived the pain of back-to-back meetings across every time zone. We know what it feels like to glance up from deep work and realize a meeting started six minutes ago.
That's why we built the only reminder that actually gets your attention — a full-screen phone call, not a toast that disappears in half a second.
