Spotify - Data Saver Feature
At Spotify, I designed a low-data music streaming experience for users in emerging markets — conducting field research in Brazilian favelas, and launching a feature that reduced data usage by 99%.

Field Research in Brazil
Traveled to Brazil to conduct field research and live user testing. Observed how users in emerging markets interact with streaming services under data constraints. Adapted designs in real-time based on what we saw — understanding that data costs were the single biggest barrier to Spotify adoption.
Data Saver Design
Designed a distinct Data Saver mode with a dark-blue theme that made the data-saving state visually clear. The feature allowed users to play four on-demand playlists using just 1% of normal data. The visual differentiation was key — users needed to feel confident they were in a safe, low-data mode.
A/B Testing & Launch
After rigorous A/B testing, the Data Saver feature proved to be a game-changer. It made streaming feel safe and accessible even without Wi-Fi. Increased adoption in target markets and measurably improved retention among users who previously downloaded music only.
Users felt confident using Spotify while on the move. It was a game-changer, making streaming on Spotify feel a whole lot safer and more accessible, even when Wi-Fi was out of reach.

The Dark Blue Theme
We designed a distinct visual mode so users could immediately see they were in Data Saver mode. The dark-blue theme wasn't just aesthetic — it was functional, giving users constant visual reassurance that their data was being protected.

Testing in the Field
We didn't just test in a lab — we went to Brazil to watch real users interact with Spotify under actual data constraints. The insights from field testing fundamentally shaped the final design. Features that seemed intuitive in Stockholm needed rethinking for São Paulo.

Design for Emerging Markets
Designing for data-constrained markets isn't about stripping features away — it's about making the core experience feel complete even within constraints. The best Data Saver mode is one where users don't feel like they're missing out.
