I hate throwing away food and often buy food I already have or that my girlfriend has bought. I have been trying to think of ways to monitor what food is at home and to reduce the amount of food wastage in our home.
I think an app that allows you to scan shopping receipts, the contents of which are automatically loaded into a database and synced across multiple apps would be very useful.
It could be monetized using the freemium model, e.g. more complex functionality the more you pay and also by integrating with online shopping engines such as instacart.
Any feedback on this greatly appreciated.
