9. Most (seeded) apps look like this

10. Instead of… like this

11. Why? Everyone wants to be ‘viral’ Virality is how many users join based on the activity of other users over a period of time (my own definition). E.g. for every user engaging in the app, another user engages for each time period (a viral rate of 1 = true viral)

12. But… A viral rate of 1 is extremely difficult – it’s normal to be much lower (e.g. for every 10 users you get one more in each time period) So – if people only use your app once, there’s only one time period. If you seed it to ten people, you’ll only get one more user.

13. The answer Retention rate! To make your app spread virally, you need to keep people coming back. Even with a viral rate of 0.1, if you’re users come back every week, they’ll double every ten weeks

14. Turn this… (50% retention)

15. To this (99% retention)…

16. And if you get the viral right as well, maybe even this….
