Describe your week in plain English and Timely generates a full schedule respecting availability, roles and your custom rules, then lets you fine-tune with drag and drop.
Publish a schedule and every employee receives it by SMS automatically — no downloads, no logins, with open rates around 98% as the site claims.
Set max hours, required rest between shifts, minimum staffing or 'always have a keyholder on' and Timely warns or blocks the save before a bad shift is published.
