About

Hi, I'm Brani 👋

I'm the founder of Rapivio and a Business Information Systems student at Uni Hohenheim in Stuttgart. For over two years, I've been building mobile apps with FlutterFlow and Flutter — for my own projects and for founders who want to validate ideas fast.

I believe great apps don't have to be expensive or complicated.

Process

From idea to app in 4 steps

1

Discovery call

We talk about your idea, goals, and scope. 30 minutes, free, no strings attached.

2

Plan & design

I map out user flows, data model, and create a clear project plan with a clickable design. You see exactly what's being built before development starts.

3

Build & test

I build your app in short sprints with regular updates. You test along the way and give feedback. After 25% — you decide if we continue.

4

Beta & launch

Final testing, beta phase with real users, then App Store submission and go-live. After launch: support as needed.
