Built a free app to discover gluten-free products at Costco — would love your feedback

I'm a GF shopper who got frustrated hunting for products at Costco every trip.

Built Checkit to solve it: basically a map of what gluten-free products are available at your Costco location.

It's free and still being built out. I'd genuinely love feedback from this community:

• What products do you hunt for most?
• What's the biggest friction point?
• What would actually make this useful?

Check it out: http://getcheck.it

Thanks for the feedback!
