The brief
Osortoo already ran contests on the web. This engagement turned that product idea into a giveaway and winner-selection mobile app — UI/UX for running contests from a phone, not only a browser.
The challenge
Moving a web contest tool to mobile is not “shrink the site.” Touch targets, interrupted sessions, and on-the-go moderation change the product. Winner selection and giveaway management needed to feel native to a phone while staying familiar to existing Osortoo users.
Approach
We used the web product as source material, then redesigned flows for mobile realities: fewer steps per screen, clearer confirmation states, and hierarchies that work one-handed. The app had to feel like a product, not a responsive afterthought.
What we designed
- Giveaway creation and management UI
- Winner selection experience
- Mobile-first patterns adapted from the web product
- Screens ready for engineering handoff
Outcome
Osortoo gained a mobile UI path for contests and winners — extending the brand beyond the redesigned marketing site into a usable app experience.
