Winsome is on the way

Winsome

in development

Small wins. Big momentum.

Winsome is a personal productivity app built around one habit: writing down up to three wins every day. Each win takes seconds to log, and a category keeps it organized.

Three wins a day
Log up to three wins daily, small enough to actually stick with.
Categories
Tag each win so patterns show up over time.
Progress over time
Watch consistency build into momentum.
Daily reminders
An optional nudge at the time you choose.

Behind the studio

Merixu is a one-person studio. I'm Ujjwal Tyagi, and I design and build every app end to end: the idea, the interface, the backend, and the store listing.

Most of my work pairs React Native and Expo on the front with Java, Spring Boot, and Supabase behind it.

Mobile

TypeScript

Backend
