I recall the original post about Lungy.

Having had an incentive spirometer prescribed for post-surgical use after being on bypass, my experience was that it seemed boring and like a waste of time, so anything that makes breathing exercises more engaging and feel more worthwhile is a win.

Yes, exactly - that's what I saw working on post-op wards – the spirometer would just sort of sit on the bedside and collect dust.
