Overview
Signal Test is a product developed by PT. Immobi Solusi Prima for tracking network performance in specific areas using geolocation. This application is a redesigned version of “Signal Viewer,” which was initially released around 2018and primarily used by internal technicians for field testing and monitoring.
In 2020, the app was rebranded and officially published on the Google Play Store, expanding its reach to the general public. It was marketed as a useful tool for Indonesian users traveling to their hometowns (mudik), especially in remote or rural areas, to help them monitor and report network quality easily.
Exploration
We are planning to new branding of previous version app and rearrangement of existing features in the application. After exploring “Signal Viewer”, I tried all the features and found things that can be redesign to improve the branding of the app itself.
Comparison with existing UI
After identifying key usability challenges, our design direction focused on simplifying interaction and improving readability. We aimed to make network testing effortless and intuitive for both technical and non-technical users.
We reimagined the app’s structure from the ground up — turning overwhelming layouts into clear, guided experiences. The new design features a clean dashboard, easier access to key functions, and a smoother flow for testing and monitoring signals.
