My feedback suggestion is that I’d like the Monzo app to use some AI to make recommendations on how I could improve my spending habits.
Like… “Allan… you’ve spent a small fortune in Pret this week. Maybe rein it in next week so that the kids can actually go to Disneyland?”. In their tone of voice, of course.
What’s your thoughts?
Or how about they message you a photo of the gym if you spend too much on JustEat… that may work in my case 
Retitled your idea to make it slightly more generic as I really like this idea. A few other banks have this now and it’s very insightful seeing “did you know you spent £100 at Starbucks last month” or you spent £200 on things under £10 last week"
It is far too easy to overspend in retailers without actually realising so I’m all for this idea too!
Or a photo of your waistline! Now that would be clever.
Now nobody will read it! 
Better 
You could do this by …
Monzo IFTTT everything you spend at Pret add to Google sheet
Then another applet if sheet reaches row 10 send notification to phone “stop eating Pret”
Only thing you’d need to do is clear your sheet once a month or whatever timeframe!
I’d like a robot to do this for me 
In the interim the AI/Robot needs to see real uses, if enough of demand the development fairies fly down and code it ha ha…
You could use the Emma app as well it gives you insights like this.
I’ve got Alexa in my life. I can’t handle an Emma too.
Cortannaaaaa then?
