Nifty product! I think I'd purchase an app if I could get gifs without the watermark. It's a bit annoying to me. Nothing against your product, just giving feedback from this users perspective :)
That's completely understandable. To tell you the truth, we would also want to provide the GIFs without a watermark. However, we need to create brand awareness. Let's hope we will get to the point when we can remove it very soon :)
