What offline-first changes in a mobile product

Start with the working experience

Remnesa stores flashcards and study sessions on the device. A connection is an option rather than a condition for learning. That changes the architecture: the local data model must support the real product, not merely cache a server response.

Make the connected boundary explicit

The connected option uses versioned mutations, retries and an API backed by PostgreSQL. Study remains local, while synchronization is a separate concern with its own failure cases.

Make ownership part of the interface

Import, export and media workflows are part of the engineering and the user experience. They help people keep control of the material they build. Those flows deserve the same attention as the main study screen.

The product behind the decisions

Remnesa

A calmer place to learn. Personal flashcards, thoughtful review sessions, and the freedom to study wherever life takes you—even offline. We also prepared the store assets, fully set up both store listings and released the iOS and Android apps ourselves.
