Modern mobile apps are powered by the cloud

We asked two questions to our mobile customers:
What makes your mobile apps unique?
Where are you spending most of your time?

Concrete Software builds cross platform mobile games
Concrete Software has been making hit mobile games
like Jellyflop and PBA Bowling Challenge since 2003.
With Amazon Cognito, We
can build games much faster
and provide great user
experience to our customers.
Keith A. Pichelman
CEO, Concrete Software
”
“ •  Provide a seamless user experience across devices
and platforms to our users.
•  Store save games in the cloud and synchronize them
across all of a user’s devices without creating or
hosting a backend.
The Challenge
The solution
•  Amazon Cognito helps us securely access our AWS
resources.
•  Cognito Sync gives us flexibility to save data in the
cloud, and cache it on a user’s devices, without
managing any backend infrastructure.

Amazon Cognito Sync
Offline: The client SDK manages a local SQLite data
store to allow the app to work even when connectivity is
not available.
Fast: The methods to read and write data only interact
with the local SQLite database.
Intelligent Sync: The sync method compares the local
version of the data to the cloud sync store, pushes up
deltas and pulls down new changes.
Flexible Conflict resolution: The sync method first
reads the changes then writes its local changes to the
cloud sync store By default Cognito assumes that the
last write wins. Developers can override and
implement their own conflict resolution programmatically
Local SQLite Cache

Integrating Cognito Sync functionality is simple
Initialize the CredentialsProvider and CognitoClient
Call synchronize on the dataset
Create or open Dataset and Add Key Values
provider = new CognitoCachingCredentialsProvider (context, AWS_ACCOUNT_ID,
COGNITO_POOL_ID, COGNITO_ROLE_UNAUTH, COGNITO_ROLE_AUTH, Regions.US_EAST_1);
cognito = new CognitoSyncManager (context, Regions.US_EAST_1, provider);
dataset.synchronize(new SyncCallback(){..});
cognito.openOrCreateDataset(datasetName);
dataset.put(key, value);

Integrating Cognito Sync functionality is simple
Initialize the AWSCognitoSyncClient
Create or open Dataset and Add Key Values
DataSet *dataset = [syncClient openOrCreateDataSet:@"myDataSet"];
NSString *value = [dataset readStringForKey:@"myKey"];
[dataset putString:@"my value" forKey:@"myKey"];

AWSCognitoSyncClient *syncClient = [[AWSCognitoSyncClient alloc]
initWithConfiguration: configuration];

[dataset synchronize];

Analyze User Behavior: Amazon Mobile Analytics

Amazon Mobile Analytics
Scalable and Generous
Free Tier
Focus on metrics that
matter. Usage reports
available within 60
minutes of receiving data
from an app
Fast
Scale to billions of
events per day from
millions of users.
Own Your Data
“Easily collect, visualize and understand your app usage data at scale”
Data collected are not
shared, aggregated, or
reused

Getting Started with Mobile Analytics in 3 steps
Sign up for AWS Account and create or use existing Cognito ID in
the AWS Management Console
View engagement and session activity reports in the
AWS Management console within minutes
Download and integrate the Mobile SDK with one line of
code (Android/FireOS, iOS)

Key Business Metrics
(with one line of code)
1.  Monthly Active Users
(MAU)
2.  Daily Active Users
(DAU)
3.  New Users,
4.  Daily Sessions,
5.  Sticky Factor,
6.  1-Day Retention,
7.  Avg. Revenue per DAU,
8.  Daily Paying Users,
9.  Avg. Paying DAU

Track Retention
User retention is a key
indicator to judge the
outcome of a marketing
campaign, new feature
introduction, UX changes,
app updates, etc.
Mobile Analytics provide four
charts to track daily or
weekly rate of returning
users, after first use of the
app

Get behavioral insights into app specific
actions that your users take
Reports provide a view of how often custom
events occur. You can add further context
with Attributes and Metrics, to each custom
event
Examples
Track the number of
Likes/Shares, per
article, in a news app
Understand player
abort rates per
level, in a game
Number of songs
played, per user
session, in a music
app
In-app item popularity
in a shopping app
Track Custom Events

Integrating Mobile Analytics is super simple
Initialize the MobileAnalyticsManager. That’s it! Get Session
Activity in the AWS Management Console.
For Custom Events activity reports, add events.
Add OnResume() and OnPause()
private static MobileAnalyticsManager analytics;
analytics = MobileAnalyticsManager.getOrCreateInstance(
this.getApplicationContext(),"yourCompany.yourAppId",
Regions.YOUR_REGION, config, cognitoProvider );
EventClient eventClient = analytics.getEventClient();
MobileAnalyticsEvent visitEvent = eventClient.createEvent("speedSet");
eventClient.recordEvent(visitEvent);
analytics.getSessionClient().resumeSession();
analytics.getSessionClient().pauseSession();
Analytics.getEventClient().submitEvents();

Integrating Mobile Analytics is super simple
Initialize the AWSMobileAnalytics object. That’s it! Get Session
Activity in the AWS Management Console.
Submit the event. If we don't call submitEvents, events
will automatically be submitted at periodic intervals.
Create add Custom Events
[eventClient submitEvents];
id<AWSMobileAnalyticsEventClient> eventClient =
analytics.eventClient;
id<AWSMobileAnalyticsEvent> level1Event = [eventClient
createEventWithEventType:@"level1Complete"];
AWSMobileAnalytics* analytics = [AWSMobileAnalytics
defaultAWSMobileAnalyticsWithIdentifier:@"someuniqueid"];

Outplay Entertainment – Amazon S3 Connector via AWS Mobile SDK
Outplay Entertainment is mobile-focused game
developer on a mission to deliver fun, free and
innovative games for smartphones, tablets, and social
networks.
With Amazon S3 connector, we can
improve the users experience by
dynamically downloading game assets
in the background. No long up-front
delays for our users.
Douglas Hare
CEO, Outplay Entertainment
”
“ •  Improved User Experience. Using the Mobile SDK,
they can download the game assets in background
while the user starts playing the game. No limits on
downloading extra assets.
•  Dynamic updates. They can update the assets
dynamically and avoid AppStore release cycles.
•  Unquestioned Scalability. Different assets for
multiple screen densities go up to 170 MB+. By
storing this data on S3 and directly downloading to
the mobile device, they can scale seamlessly.
•  Excellent Performance. Highest resolution devices
end up downloading about 90MB of extra content.
