Hello Devs,
I am looking for an ad space in top iOS app review websites for my app. I have analyzed a lot, but I am still in a confusion to find which would be the right choice.
Please share your thoughts on websites and the results of ad campaigns if you have done that for your apps previously. I am looking for a banner ad that need to reflect some improvement on my ROI. I am not in a very high budget to go for an ad in Mashable or Techcrunch

I need some websites with medium ranged cost. So I am looking forward to your valuable suggestions and results you made for your apps from those banner ads so that I can choose a right one.
Please share your experience.
Looking forward to your replies.
Thanks in advance,
Tessa.
