Entry, Engagement, Ecosystem, 3 Pillars of App success
PS: Tl;dr version at the end.
3E Formula.
Every popular app gets a high score on when you apply the 3E formula. But what is 3E ? 3E formula helps you growth hack your app objectively.
App score (is proportional to) Entry x Engagement x Ecosystem
S ∝ EnEgEc
Now, let us understand how 3E works. It is proportional the product of 3 functions.
Entry (En)
How many entry points does the app have, or what are the ways by which a user can come back to your app.
Engagement (Eg)
People think engagement is the holy grail metric for app success. But did you know engagement can be broken down into just two type of actions? A core action followed by a trigger to another core action.
Eg = Ca → Ta → Cb → … Tn → Exit
Ecosystem (Ec)
Ecosystem can also be called Scale. This function will be boosted by user acquisitions. Also, this is one hardest variable to boost.
tl;dr
- En = Number of times user opens the app.
- Eg = Number of minutes user spends on the app.
- Ec = Number of users who are using the app.
- Your success is the product of the above 3.
S = kEnEg*Ec
