interface App

An App is the main client-side entry point for interacting with an Atlas App Services Application.

The App can be used to:

  • Register and authenticate users.

  • Synchronize data between the local device and Atlas using Device Sync.

This can be done as shown below:

    class MyApplication {
val app: App = App.create("<APP_ID>")
val realm: Realm

init {
realm = runBlocking {
val user = app.login(Credentials.anonymous())
val config = SyncConfiguration.Builder(
user = user,
partitionValue = "my-partition"
schema = setOf(YourRealmObject::class),
