Not free but expensive for what it is. Also has HUGE watermark – GIF Maker for Instagram- GIF to Video to Instagram Review

This app is not free. In order to use it fully you need to pay $3.99 to "unlock" it. There are far better apps out there that are cheaper than this, some are .99 cents. If you're looking for a gif to video app for Instagram then pass on this one and go for a better, cheaper app. This app only has so many 5 stars because they were giving it away for free if you gave them a 5 star rating. Such a scam to get free 5 stars for a bad app.
