Organize and Remind Yourself with Time  Blocking

Organize specific time slots for tasks and meetings.

Note

Simple,
Yet Powerful Notes

Write down agendas, tasks, and ideas directly in your calendar. Simple, streamlined, and effortlessly integrated into your daily routine.

No more copy & paste

Instantly send links, notes, or ideas straight
from your mobile to Arch Calendar.
Stay focused on what matters,
without switching devices or losing momentum.
Available on iOS and Android

Built for Google Calendar

Arch Calendar works with Google Calendar. Any calendar block you create is set to Invisible (private) by default, so your colleagues and people on shared calendars can’t see these blocks unless you manually change the visibility.

Privacy by Design

Your data is encrypted at every stage to protect your privacy without slowing things down. Arch-only details like Space, Priority, Links, and Notes never appear in Google Calendar.

Our Values

Minimalism: The Art of Productivity

We believe in the value of minimalism in software. Just as the arch was designed to support immense weight using only a few stones, we aim to maximize productivity through simple yet powerful elements.

Your Calendar, Reinvented

Our days are defined by countless meetings and personal projects, with the calendar always by our side. Because we check our calendars from start to finish, we believe they're the perfect hub for integrating tasks, schedules, and ideas.
