Connect friends using 'Username' or show friends list.
The biggest problem that exists is connecting with friends. Splitwise should allow people to be found using a simple username & connect them with ZERO email involvement just like on Instagram. Nobody scans QRs to connect each other. People don't wanna send each other links to connect.
Emails or 'sending' invites shouldn't be involved at all & nobody should be able to see my email ID. People should be able to connect each other just using the 'username' or if they wanna send links, then 'splitwise.com/user/username' to ease it.
Also, we shouldn't have to connect to the Google account to find friends or connect anyone. The app should allow users to just scan their device contacts & connect with friends (if the friend has allowed visibility using email) if their friends are found using the same email ID just like how WhatsApp does with mobile numbers.
EASE IT. CONNECTION IS TOO MESSY.
