Gramblr is the only program out there that I have seen with the ability to post directly to Instagram via PC. They appear to have fixed all the bugs with broken hashtags, an earlier complaint for many users. Thus far, I have been floored by the results that Gramblr provides, especially for a free program! There are many tech companies out there that would LOVE to have the backdoor into Instagram that Gramblr has, but that isn't even my favorite part about Gramblr. They have the most effective tools in gaining likes, even local-area likes! You can add likes to things you have already posted or images directly posted through Gramblr. They even throw in 50+ free likes for you every now and again. You earn coins, the currency for gaining likes, by liking other Gramblr users' photos. It's a win-win for everybody! I LOVE THIS PROGRAM, PLEASE KEEP IT FREE!!
