Will you use a bill splitting app like Let's Dutch? How do you normally split bills?

Some of our enterprising juniors from NUS just launched a bill splitting product (similar to SplitWise in US).

Was wondering would you use something like this? Or if not, why not? Or how do you normally split your expenses these days? Using Google Pay, GrabPay or PayLah! and more?

P.S Reminded us of the painful early days launching the Seedly app 😂
