1 Stair machines
Define what each level means (steps per minute) and how big a step is. You can name each level.
2 Activity plan
Pick a machine and build your workout as a list of (level, minutes). Drag segments to reorder.
3 Align & preview
Upload a GPX or FIT file with heart-rate data, then slide the plan to line it up. (Optional — without a file, a record is written every 5 seconds.)
Drag the graph left/right, or type an offset. Green = plan, purple = heart rate. Shaded band = your workout window.
4 Generate & download
Produces a FIT activity with laps per segment, plus heart rate, cadence, distance and altitude.
Keep your own copy of anything you upload
A file you upload here is only ever read, never changed, and the FIT this
produces is a brand-new file. Keep your own copy of the original all the same —
it is the only way back if the generated activity turns out not to be what you
wanted.

arising from its use.
