taxx.lu Scanner

Mobile App Design & Advertising Campaign

A complete design project for taxx.lu, a Luxembourg-based platform that simplifies tax filing — no need to be a tax expert to submit your tax return. The work centered on the taxx.lu Scanner mobile app, which lets users scan the QR code in their tax return, photograph or upload tax certificates, and have them automatically imported into their return on taxx.lu.

The project covered the full app experience: onboarding flow, the complete scanner journey (QR scan, document capture, upload, and automatic import), and store screenshot sets for both the App Store and Google Play, fully localized in three languages — French, English, and German — to serve Luxembourg’s multilingual market. All built on the brand’s clean navy-and-white identity, designed to make a traditionally stressful task feel simple and trustworthy.

The engagement also included the production of three advertising videos for digital out-of-home (DOOH) campaigns, displayed on public screens in high-traffic locations across Luxembourg — extending the brand’s reach beyond digital channels into the physical spaces where people commute and circulate daily.

Deliverables: mobile app UI design, onboarding flow, App Store and Google Play screenshot sets in three languages (FR / EN / DE), scanner flow screens, and three DOOH advertising videos for nationwide public display.
