I’m happy to announce that bill splitting has left labs, and we’ve rolled it out the wide world of all Monzo users!
Thanks so much for using it over the last month and providing loads of feedback. We’ve fixed the show-stopping bugs you reported and added the top-requested missing feature of adding non-monzo users. We’d like to think bill splitting is in good shape as a successor to the old functionality (“Split cost with monzo.me”), and I hope you agree it’s a good step in the right direction.
Often we can’t address every bit of feedback we see in labs (but we do read all of them!), so I’m sorry if you haven’t seen your particular request addressed in the wider release. Labs was really helpful for a feature like this because it let us release very early; e.g before we even had a full Android version ready. Rolling out a feature to all users doesn’t necessarily mean we consider it feature-complete or “done”. It lets us extend the feedback net to everyone once we’ve addressed the glaring issues in labs and we think the feature would be an improvement to everyone’s experience. In addition, we have some exciting work in progress that expands upon the idea of bill splitting (as teased in a post in this thread 
) that I hope will address some more of the feedback here!
