Hello,
Greetings from Milecore!!
I read the description in full & we are very much aware about instagram app. As far as RATINGS are concern we do have a rating bit below due to: One WP Project where client wants to use the camera for screen shot purpose but as we do have our own policies that we won't allow camera access to developer, he has given 1.5 only out of 5.
Else you can check all ratings for Mobile Apps, those are up to the mark + we do have 100% completion ratio.
For portfolio & other details kindly refer to your PMB.
Thanks.
