GROPYUS Home is the primary tenant-facing digital channel across all GROPYUS apartments – a single app that needs to work across buildings with different hardware setups, serve diverse tenant needs, and scale across the portfolio.

The redesign shifted the product vision from a static remote control to a modular, real-time digital home companion: smart home controls, energy insights, keyless access, and tenant services, all built on one adaptive UX backbone.

I led the design effort alongside a project lead and brand designer at GROPYUS, with an external design agency involved during the development phase.

My role covered defining the strategic direction and UX mental model, running the design sprint, synthesizing user research, performing market research and competitor analysis, defining the full feature set, managing stakeholders across product, tech, sustainability, research, and sales teams, delivering information architecture and wireframes, and collaborating on high-fidelity UI.

Discovery

Understanding current pitfalls through UX audit, research synthesis, and identifying new opportunities

I utilized existing qualitative research based on tenant interviews and feedback on the current app use, ran a UX audit, and organized a workshop with the design team, PM, and tech to collectively map frictions and UX pitfalls. Alongside this, I conducted market research, industry trend analysis, and competitor research across all key feature areas.

I mapped user journeys through the 'moments that matter' framework to understand where the expansion into real-time feedback, sustainability, and proactive communication could create meaningful new value for tenants.

Painpoints

App required apartment WiFi connection to control devices, limiting perceived smartness.

Tenants weren't able to find all smart home controls due to limited navigation and discoverability.

Air quality data (temperature & humidity) was collected by sensors in every room but never surfaced to tenants.

Scenes had limited customization and a hard-to-discover access point.

Consumption data was static and fact-focused, with no actionable outcomes or contextualization.

Access controls (digital key, remote unlocking) were absent.

No outside-app communication: no widgets, no meaningful push notification system.

Constraints

Not every building has the same hardware setup, the app needs to adapt without fragmenting the product.

Some features depend on backend readiness and hardware availability per building.

Opportunities

Real-time sensor data (temperature, humidity, heating) already exists across all apartments, enabling data-driven features at no hardware cost.

Modular architecture enables scalable rollout across diverse building configurations and opens a services monetization layer.

New B2C brand integration creates a strong product differentiation and ESG activation moment at scale.

Definition

From static smart controls to a real-time digital living companionship: mental model, information architecture, wireframes, and brand integration

The core direction was to evolve the app from a smart home remote into a proactive digital companion – real-time, communicative, and sustainability-focused. Key to this was establishing a modular architecture: one UX backbone that adapts per building configuration, avoids product fragmentation, and enables scalable rollout across GROPYUS's portfolio, with future-readiness for white-labeling and services monetization.

In collaboration with the external design agency, we integrated the new GROPYUS B2C brand into the product. The visual direction is grounded in Swiss design principles: rational grids, modular card surfaces, bold numerals for glanceable data, and an intentional three-color system — green for active states, orange for attention, lilac for tips and assistant communication.

Develop

High-fidelity UI, user flows, and a cross-platform, agentic-ready design system

We delivered high-fidelity UI and user flows across three distinct app areas, while ensuring that a) visual design is grounded in the defined brand identity and b) experiences are scalable according to the modular architecture.

We established a mobile design system for iOS and Android, crafting components, defining consistent rules, and making them composable, while ensuring that the naming conventions & component usage documentation is clean & in place to provide structured & relevant knowledge for Claude Code.

Delivery

App in active development, full release expected Q4 2026

The redesign directly addresses all 5 KPIs – adoption & retention, app store rating, ease of use, improved features and information architecture, and GROPYUS brand promotion. It introduces a real-time, modular digital home companion with a new visual identity, a unified IA across all app areas, a full new and revisited feature set, and an agentic-ready mobile design system for iOS and Android.

As the sole designer supporting engineering, I continue detailing interaction patterns, haptics, screens, and user flows, and standardizing the design system to ensure production-ready handover.
