What users could place and compare in the room.

ARrange came out of Netguru’s R&D work: a demo app that puts furniture into a real room in augmented reality, in real time.
It was built to show retail clients what AR can do at a Netguru event in Berlin — letting the end user try furniture arrangement, and a prospective client see a way to improve their customers’ experience and their conversion.
Five weeks, a live audience, and no appetite for a crash on stage.
The app had to be crash-free inside a short timeframe, with no lag and no unpredictable behaviour.
AR had to earn its place: helping someone picture the right set of chairs in their own interior.
Several chair models, colours and wood types had to be on show, with snapshots users could share — and the whole thing had to stand apart from other R&D retail apps.

What we did
Built in SwiftUI for iPhone, ARrange lets a user set two or three chairs around a table in AR, standing in for their home.
Chairs can be positioned at different angles and locations, even partly hidden behind a table to imitate how objects really block each other.
Users browse the available models and switch chair colours and wood types directly, with scaling that keeps products the right size in perspective.
A built-in snapshot feature captures the setup and shares it through the system’s own messaging or email.
Unit tests on the ARViewModel and crash analytics through AppCenter kept the app steady, with onboarding screens, a coaching overlay and a pre-recorded demo video as a safety net for the live presentation.
