Doing one minute of almost anything will not cause adaptation or any improvement in your fitness - or a very minimal improvement and then nothing further whatsoever. We're talking 'you are almost completely sedentary, this might help.' You know what else is good? Going for a walk, and you don't need a stupid app to help you do it (also there are no shortage of youtube videos and subreddit routines, all for free, no personal/device data collection, nothing.)
This "you can work out in 1 minute" is just another version of the 80's/90's "crunch your abs /air box / step your way to this beach body!" crap.
The studies are bunk - done on college-age people whose bodies are already in pretty good fitness.
Exercise is work.
It's hard.
It's supposed to be.
There are no shortcuts.
You need to get lots of low intensity exercise, a moderate amount of...well...moderate intensity, and a bit of very high intensity exercise. Ideally in that order - establish a "base" over weeks if not months before you dip much into the latter two.
