How many days before asking the user to pay to unlock app features ?

[hookshy]

What did best for you when choosing right timeline before asking the user to pay for locked feature ?

I wouldn't put it in "days" but rather in "how many times it was used"

Tell us how how many times you let user open your apps !

 

[Cableguy]

I would say not less than 10 times but not more than 15, without inviting them to buy

My Windows software packages have 14 days free trial periods.
If I had Android applications with free trial periods, I would do 14 days again...

From my perspective the answer is same as answer to this question:

"At what point is the user invested in the app?"

That could be defined by almost any unit that makes sense for the app:
- Number of launches
- Time spent in app
- Level reached
- Number of documents shared
- Number of songs played
...etc...
