These days, most of the users expect apps to work even when they’re offline. Else, bad network connection translates into poor user experience. Near about 21% users uninstalls an app just after one use. In app messaging, Push notifications and offline mode helps to retain users. Offline mode is necessary for delivery apps having GPS navigation, banking apps and apps for urgent medical assistance. Users like offline apps because it can work constantly without delays, can load immediately, and consume less battery.

Types Of Offline Apps-

Based on the nature and function of app, offline apps are divided into 3 categories-

One user can edit other user’s data- making edits to an offline Google doc type app.
Data can be edited and synched offline, for example, note taking app.
Data stored offline- without any editing functionality, eg., On-demand Uber – X app
Selecting An Architecture To Create Offline App-
While selecting the architecture for your offline, consider the following points-

• Why is it important to know how and where to cache the data?
• What is the reliability of caching?
• How to handle concurrency?
• Which safeguards are in place to handle data conflicts?
• How is this architecture going to handle connectivity changes?

Types Of Offline- First App Architecture-

The data storage, sync and access may change according to the device, server and architecture. Some of the best development approaches are as follows-

Caching-
Data caching on local browser/server is simplest approach to help users with data reading in offline mode. This offers access to data on a device, renders the UI, providing a predictable user experience within a short time.
Manual Replication-
With this users can edit the data in offline mode by marking changes in objects. All changed objects are sent by push and pull operation once the network connectivity recovers.
**Real Time Data Sync By Platform– **
In this case data synchronization is automatic. Changes are send between device and server in minor binary format. Only some particular operations with data are synchronized, capturing the information intended by user, permitting the system to automatically resolve any conflicts, This focuses on performance because there is no manual intervention.

Selection Of The App Types Based on Offline Mobile App Architecture-

One should look for quick data retrieval upon multiple requests, complete offline capabilities and no reliance on the UI while selecting the architecture of offline-first application. On-demand type offline architecture are good for e-commerce apps, news apps, real time apps, map apps etc. Offline architectures are suitable for notes taking apps, weather apps, email apps, finance type apps, messaging apps.
