Expense manager.. but for lazy people

There are plenty of expense manager app in the market, but most people find it very much boring to add entries, check expenses on regular basis. Eventually it unable to solve the problem of keeping user in his/her budget.

I was just thinking of a possible solution let me know your feedback.

1. You will get a phone call on daily basis. It will ask you “bhaiya aj kitna kharcha hua” , you can reply “ aj 200 ka bus main, 500 ka zomato main lag gaye”

2. A physical statement will be delivered on your address on month end.

3. There will be an app also if anyone wants to track expenses in realtime or add manual entries, configuring call timing etc.
