Your comment was quite the ride.

> There doesn't need to be any justification. If that's what OP wants to charge then that's reason enough.

Yep, makes sense.

> That being said, OP should probably realize a lot of people don't pay for software--even in HN.

Indeed. Maybe people pay even less on HN, seeing as many of us can hack together something for personal use.

> That's why OP needs to make sure the users are the product and find some way to sell the user data to advertisers.

Er…

> OP should contact restaurants and allow them to place ads in the recommendations. He should also sell access to user data and allow restaurants and advertisers to target free users.

Wait, what? This is app for eating at home, restaurants have nothing to do with it.

> He can have a subscription tier that gives you privacy.

Full-on dystopia.
