A viral loop is where the consumers of a product become the primary marketers. Growth is fast, cheap, and self sustainable as users are driven to generate more users. This slide deck explores the importance of setting up viral loops within mobile applications in order to generate free exposure and downloads.

invite my friends to this app.
Viral, but not yet a loop…

7. Why are viral loops so important
for indie developers?

8. A: Because indie developers can’t
afford to pay $2.27 per install.

9. How does a viral loop work?
1 user -> invite 1 new user = 2 users
2 users -> invite 2 new users = 4 users
4 users -> invite 4 new users = 8 users
8 users -> invite 8 new users = 16 users
16 users -> invite 16 new users = 32 users
32 users -> invite 32 new users = 64 users
64 users -> invite 64 new users = 128 users
128 users -> invite 128 new users = 256 users

10. How does a viral loop work?
VC = N x P1 x P2
This stands for “Viral Coefficient”
!
The average number of customers who are invited by each
active user who invites people.
!
The proportion of invited users who tend to actually sign up
and become active users.
!
The proportion of active users who tend to invite other people.
VC

N

P1

P2

11. !
• If VC is greater than 1, you can expect to see the growth
of your viral loop increase exponentially into every area
possible.
!
• If VC is less than 1, you’ll need to constantly monitor
and remarket your content to keep it going.
!
• If VC is 0, you will see no growth whatsoever.

13. Implementing a viral loop on iOS
• Plan viral loops early on in your product’s
development. Social integration is essential.
!
• Viral loops are an iterative process.
!
• Limited to App Store policy. Can’t setup
incentivised referral loop like Dropbox.

14. Here are 3 examples of viral
loops with mobile apps

15. 1. Social Competition
• User downloads a game.
!
• User sets a score and sends it to a friend as a challenge.
!
• The user’s friend receives a push notification, prompting
them to download the app and beat their peer.

16. An example…

17. 2. Request Help From Your Friends
• User is stuck on an action with an app/game.
!
• User requests help from friends in order to progress
through the app.
!
• Initial user receives help from a friend, then progresses.
Other user joins the app as a referral.

18. An example…

19. 3. The Queue Jumper
• Create a queue at a point within an app (on sign up
or before reaching a higher level).
!
• Allow users to skip the queue by inviting friends to
the application (Mailbox).
Mailbox used the above strategy to build a waiting
list of over 1 million users.

22. In Summary…
• Developers that execute a viral loop perfectly often
have major growth in a short space of time.
!
• For every user you acquire, if they feel compelled
enough to invite one more friend, from the outset -
the need to spend on expensive CPI channels
halves.
!
• Viral loops are cheap to implement.
