It builds the routines that fit naturally into your schedule — and brings all your calendars together in one place.




Outlook, iCloud, Google, your boards — in one clear view. Two-way Outlook sync; the rest read-only via an iCal link.
Set a goal and Calendæ places the sessions in your free slots — respecting your working hours and your lunch break.
Habits kept, measurements tracked, compounding effect: each small session adds to the last, day after day.
Paste an iCal link (Outlook, iCloud, Google) or connect your Outlook account to create and edit your appointments.
Piano, running, reading, a treatment to follow… choose the rhythm and the length of a session.
Sessions drop into your calendar gaps on their own. You check off what's done — even afterwards.
Three reasons Calendæ works where the others stop.

Pick a rhythm — piano 3×, running 2×, 20 min of reading — and the sessions drop themselves into your free slots, respecting your working hours and your lunch break.

Rising streaks, cumulative time, records broken, “X days without…”: your compounding effect is right there. You come back each day to watch the curve climb.

Outlook, iCloud, Google and your routines in one clear schedule. No more juggling a calendar, a habit tracker and a planner — Calendæ ties them together.
Calendæ adapts to the nature of what you track.
Calendars handle your time. Trackers handle your habits. Planners handle your day. Calendæ does it all — and connects them.
