So I recently used a shared tab for the first time. Amazing!
Except for when it wasn’t. Let me explain.
It did everything that it was meant to, but I think that it could do with a bit more help to the user around the edges. Two examples:
when I went to pay, the app asked me for my PIN (which was odd as I usually auth with fingerprint). Then the tab was just settled immediately. I was expecting a nice explanatory screen showing where money was going and why. Or, at the minimum, an “are you sure?” prompt. But no.
my friends then messaged me asking why one of them got much money than I owed them and one much less. I pointed out that the app had netted off the money owed between them, but we still spent 30mins over WhatsApp checking the maths.
So, I think what I’d suggest is:
Somewhere in the app to show what everyone (currently) owes/is owed and why (hopefully shareable by SMS/WhatsApp etc
a better “are you sure” prompt when going to settle, compete with the option to send an explanatory “this is how much you’ll get and why” message
a better in-app experience when paying / receiving money from a tab. Maybe a link to tap to see the details, and/or more info in the notes.
