SumDay is a platform that helps people understand how they spend their time so they can build better habits, improve consistency, and make more intentional decisions.

Which integrations does SumDay support?

SumDay connects with Strava to auto-import workouts and with your Outlook / Microsoft 365 calendar to sync events. It also tracks sleep and offers a REST API with personal access tokens for your own integrations.
