I’m not if this is satire. If so, well done because you’ve written something about a “business” that is quite literally based on crap.

It’s not a “real business” by any stretch of the imagination.

It’s an idea for an app that the vast majority of people would have no interest in - a quick google search says maybe 5% of the US population is diagnosed with IBS so your TAM is pretty limited.

Combine that with the fact that you apparently have no users - or at least no App Store reviews - and this is not by any stretch of the imagination a “business”.

Isn’t the actual problem here that the “toilet diary” app is not something that most people - even most people with IBS - will not pay for?

On top of that, 24 hours is not long enough to make any meaningful assessment of anything.

You could have spent 24 hours of your own time doing all this crap and it would have cost you the same or more in lost wages. Plus sleep deprivation.

Nonsense app, nonsense experiment. Half way amusing write up. But why on earth did you waste the time?
