An audio-learning product built around persistent playback, offline access and resilient states.

Explore ↓01 / Player continuity
The experience kept the active lesson visible across discovery, album detail and playback controls.



02 / Offline learning
Availability, access limits and download behavior needed to remain understandable before and after the connection disappeared.


03 / Resilient states
Loading, empty and connection states preserved orientation and offered a clear path forward.



04 / Interaction prototype
The prototype connected album detail, offline availability, playback progress and favorites in one continuous study flow.
05 / Product context
Students already searched for ways to keep studying through audio. Estratégia Cast turned that demand into a dedicated product for discovery, playback and offline learning.
As part of a shared product effort, I contributed hands-on to the iOS and Android flows and resilient interaction states. The product launched publicly on the App Store and Google Play, with continued work in 2020 around download visibility, listened states and in-app feedback.
06 / Platform system
The shipped experience covered the same product logic across iOS and Android without collapsing platform-specific behavior.
The final source files document equivalent breadth across signup, home, search, album, player, favorites, downloads, account and support. The system continued to expand after launch rather than ending at a single release.
07 / Launch reception
At the captured launch moment, Estratégia Cast ranked #2 in Education on the Brazilian App Store. The Google Play capture recorded an equally strong early signal.
Historical store captures dated 4 November 2019. Ratings, ranking and installs are reported as observed launch reception, not as causal design impact.
