Kidney stone prevention made simpler and smarter

Kidney Stones are Brutal. Prevention Shouldn’t Be.

Most people are just told “drink more water” and “stop eating oxalates” - but real prevention is way more complicated.

What can I actually eat?

Am I drinking enough water?

Is my diet going to cause another kidney stone?

That’s where stone free ai comes in
