how much is a featured ios app worth?

Hi,

because of some private problems in 2015 I decided to sell my app. Now I try to research a little bit to find out how much is my app really worth. Maybe the community can help me?

some details:

- featured in 375 countries in the selfie section "Snap & Share"

~ 100 downloads per day

~ 2000 daily active users

> 224.000 downloads in total

- first release december 2014

some promotions runs with this app for companies like "UK Tickets - Disneyland", Clearasil
