Ask HN: Need App ideas for ice cream product

I'm working on a campaign for an ice cream product and need to develop some ideas to promote this product via an app or social media concept.

Now, I'm not too experienced in developing apps, so I figured the HN is very helpful and would love to contribute ideas since that's what its all about!

I came up with: app shows you local store locations app that let's you check-in showing your friends which flavor your enjoying

All help is appreciated. Thank you.
