Osu combines calendar management with client admin and makes it easy. Schedule appointments, plan your day, and add client notes on the go in just a few taps. We know your time is precious - that’s why we’ve made it so simple.

Osu’s scheduling tool makes life easy. In one place send invites, add events to your calendar, and view and adjust your daily schedule. For your clients, it’s equally easy - they receive an email with all the necessary details, click accept, and they’re done - in their calendar too! And if there’s a last minute change? No problem, you can contact your client from the app!
