What This Tool Does

Scenario Compare lets you save a result from any sleep calculator and compare up to four results side-by-side — for example, your current schedule versus an optimised one.

When to Use It

After running any calculator: save the result, try different inputs, save again, then open Scenario Compare to see both together.

Fields Explained

Saved Scenarios

Automatically saved when you click Save Scenario in any calculator. Stored privately in your browser.

Select to Compare

Tick the scenarios you want to compare — up to 4 at once.

Reading the Result

A side-by-side table of key metrics from your selected scenarios.

Pro Tips

Save your "before" scenario today, make one change to your sleep habits, come back in a week and save an "after" to see the difference.

Export scenarios before clearing your browser — they are stored locally and will be lost with the browser data.

You can rename scenarios to keep track of what each one represents.
