FINMAN

An app developed to keep record of the income and expenditure of someone.

• The plan is to create an android app which will help keep record of all your transactions and give you a daily, weekly, bi-weekly or monthly report.

• Inspired by the Apple Card's App which gives you detailed view of where you've spend your money and when.

• It'll keep track of how much money a person have iun which account and they can make transactions from each account.

• Future plan is to add data-minig capabilties to seemlessly adding transactions without the interaction of the user from Mobile phone's SMS or user's email.

Technologies used

• Django - python web framework

Disclaimer

Well, I did test it, but I can tell there are so manny security holes, bugs. Extra points if you can make the backend better as well.
