About Callendar
We build reminders that help people notice their next meeting and find the details they need.
Our Mission
Callendar focuses on a familiar problem: a meeting is on your calendar, but its reminder is easy to overlook while you work.
Our aim is to make Google Calendar reminders more noticeable and meeting details easier to reach. Test the alert to find a setup that fits your routine.
Our Values
Reliability
Clear setup and test alerts help you check reminders on your own device. Review permissions after changing phones or system settings.
Privacy First
Calendar access is read-only. Our privacy policy explains how information is processed and how to manage your account.
Respect for Focus
Choose reminder times and use available quiet hours and per-event settings to fit your schedule.
A Global Remote Team
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.
We focus on clear reminders, practical controls, and easy access to meeting details.
