A few thoughts on this:
Firstly, congrats on getting featured. I think there's definitely a space for this in the world somewhere, as your own twist on an established concept. Like an old school "swear jar" or one of the other rewarding/punishing apps out there I know about the concept of, but don't use or know the names of (quick google got me this list:
Want to kick a habit? The 6 best goal-tracking apps to kick your butt )
As someone who
used to be perennially late, I know change is possible! I still struggle sometimes (but I've at least managed to shift it back so the struggle to get out the door doesn't
always equate to my actually being late to the target destination). But it certainly took a) deciding for myself that I had a problem & b) wanting to change it.
Getting people to admit they have a problem when they feel they don't is one of the hardest things you can ever do in business. And that describes most people who are "habitually late". It becomes a part of their self identity.
Absolutely. It is my identity, & that didn't used to be an especially bad thing, it just was what it was. My whole family struggled to leave on time. I still think of myself as a "late person" because it still takes effort, I don't think I'm
habitually early without effort yet. (Oh gosh, it making me think of those people who still say they're alcoholics even once they're twenty years sober, maybe that's what it takes!) But I measure my victories when I find someone who mentions in passing that I'm usually early, or when an old friend actually comments on the change unprompted.
For those who want to change, this app could provide some positive (or negative) feedback, for those who don't (but whose boss wants them to) it could provide the nudge in a different way that speaks to them. (I wouldn't use this app for instance, but I have my own conscience punishing me, or if I did use this app, I wouldn't want to pay money as punishment).
However, one last thing it made me think of, alas I forget where I read it, was about a nursery who had a problem with parents picking up their kids late, so they decided to institute a punishment, & fine the parents money. What actually happened though is that late pickups
increased. It turns out previously the parents had been feeling bad about it the late pickups, but now they felt like they'd paid for it, so it was ok. It wasn't a fine, it was a service. Which also reminds of the certain group of people in London who like to park their flashy cars directly outside of Harrods (fancy department store). To them the £80 fine is just the price of parking where they want to park, no big deal.
I would make sure to offer a range of potential punishments (& rewards) because some will work for some & not for others.
