The short version

Heystack is a collaborative task and shopping list, built for friends and family sharing a list together. It detects nearby shops, like a supermarket, while you are out, and reminds you what's on the list close by. I designed the entire product, every screen.

Reminders where you already are

Instead of asking people to check a list on their own, Heystack looks at where you are and surfaces the list when it is actually useful, near a shop.


01

Share a list together

Friends or family build one shared list instead of separate ones.


02

Detect nearby shops

Heystack picks up when you are near a supermarket or another relevant shop while you are out.


03

Remind at the right moment

It nudges you there, at the shop, instead of only back home when the list was made.

Full ownership of every screen

I designed every screen in the product, working as UI and UX designer through Zemoso Technologies.

Where it stands

This was built for a company through Zemoso Technologies. As far as I know, it has not shipped to users yet, and I would rather say that plainly than claim an outcome that never happened.
