Data persistency in cross platform environments is key. We understand dealing with offline functionality in cross-OS and cross-platform environments.
Based on the operating system regulations and the technology in charge, providing offline data as well as data synchronisation are leading factors.
Caching app assets needs to be considered, just as well as technology decisions, e.g. regarding the local database. Depending on the requirements, the correct patterns for offline synchronisation need to be applied, e.g. read-only, read-write and last write wins.
