The v1.0 of the app should have

• user authenticating with their phone number
• be able to import expenses
• be able to create tags & add tags to imported expenses
• be able to share tags with friends who can then see those expenses
• be able to see the monthly aggregate value of expenses against a tag

Good to have

• pay button in the app which will direct the user to a upi app from which user pays & then user gets redirected back to kilvish with import data populated from the payment. For time being - only one or two upi apps can be supported (like google pay & phonepay).
