Free tools · Nothing to sign up for
Tools that run in your browser
These are free scheduling tools that compute on your own machine: rota and rotating-pattern generators, a nurse-to-patient ratio calculator, an acuity-weighted staffing calculator, an FTE and NHPPD establishment calculator, and an emergency department model. Each opens straight away with no account, and each exports what it produces as a CSV emailed to the address you give.
Why is there no account to make?
Because the arithmetic happens in your browser. There is nothing to log in to and nothing to give before a tool opens: the results are on the page as you type, and an email address is asked for only when you want the CSV sent to you.
Almost every free scheduling tool on the web is a trial with a grid attached. It wants an account before it shows you anything, or it shows you a result and then charges you to take it away. Both are reasonable businesses, and neither is what somebody typing 'free shift schedule maker' at nine on a Sunday evening is looking for. So these compute on your machine, with no account and no charge, and a CSV you ask for arrives in your inbox. If you close the tab without one, the work is gone.
What none of them is, is a rules engine. They know what you typed and nothing else: not who is signed off on the unit, not whose license expires on Friday, not the eleven-hour gap between the night somebody just finished and the day you are about to give them. Each page says so in its own words, on the page, rather than leaving you to discover it. The version that checks those things is the product, and there is a live demo of it that needs no account either.
When the arithmetic is not the hard part
MedAligna checks credentials, rest, ratios and overtime before an assignment can be saved, in the browser as you drag, and again in the database before the write lands. Fourteen days free, no card.
