Design that shines, tested by real users.

Zzzone, a sleep-tracking app I designed in Figma
From idea to clickable prototype
My process: designed and tested with real users

Design that shines, tested by real users ✦

Hi, I'm Mert, the designer behind HoshiLabM. "Hoshi" means star in Japanese, and I want everything I make to shine.

I'm studying Artificial Intelligence & Data Science at La Salle in Barcelona, where I design apps in Figma and test them with real people. Zzzone, a sleep-tracking app with 24 screens tested with 5 users, is one of my projects. You can see it in the photos and video above.

At HoshiLabM I offer two things:
✦ Custom app design: clickable Figma prototypes, with user testing in the bigger packages, ready for your developers.
✦ Printables: party kits and kids' charts you can download instantly and print at home.

Got an app idea or a question? Send me a message, I usually reply within a day.
