Every club, society and cafe around campus could use an app, and none of them has a studio.
A campus is full of people who need small apps: a society collecting dues, a sports club running a rota, a cafe that wants a stamp card, a class fund nobody can track.
You are already in all those rooms. A Studio gives you a storefront with your name, a shelf picked for schools, groups and cafes, and scripts for the first message. Every order is built and delivered behind your storefront.
Then the line on your CV is not an internship you applied for. It is a studio you run, with clients you can name.
