How much is my app worth?

[Sunjay Soekhradj]

So, i just created an app, a Twitter API
It helps me to get more followers, i gained 500 followers in 2days

so here is a short list of what i can do with my client

'
Auto Tweet
Check profile/Status ETC
Automaticly add peoples that want to follow you back (#TeamFollowBack)
Auto Shoutout creator (send shoutouts without typing anything...)


So here is my question; how much is this client worth? im not talking about paying per month but just a single license for ever?
i was thinking about 2$ / €2 but not really sure

I don't have twitter, so I don't really know.
(nor care to be honest)
but yea $2 is a fair price for people who really want followers.
