There's none. Before Xgram, Boostagram, and Instaget are all good, Search for those names. They are working fine back last year but since January Instagram with Facebook is hunting down this bots in 2 ways. 1st is lawsuits, 2nd your good old fashion bot killers.
There's none working today or if there is, the devs are keeping it to themselves. Here's what I suggest you do if you are into quality type of shit.
Get Bluestacks(Free) and Get your account rollin there. Download Niche pics from free copyright sites, there are a bunch of them and edit them with Image Tuner (Free) Resize, Rename, watermark on the sides for more traffic. Post like 5-10 pics a day, Like, Follow and comment on a few. In a month you'll get some sexy numbers like 200-300's on all stats just by spending 20 minutes a day and that's no exaggeration, it's really just 20 minutes daily, lesser if you have a grip of it.
