Is there any demo or beta/alpha version of the platform so, that we can get an idea about the product before investing?
Just read one post above you. He already said and i replied. Don't be that lazy. What happens If everyone comes here and ask anything not before checking it?
Does anyone know if they will release a beta of the mobile app before ICO?
I'm not allowed to say anything, but lets just say that our Engineers are working over time at the moment and I don't think you will have to wait till 2018

Also Ben and I try to monitor this forum as much as possible but sometimes we miss questions which I apologise for. If you want to engage with more of the Dev team please sign up to our Telegram
https://t.me/gatcoin our Founder/CEO is very active there and also considerably smarter than me so its a great place to ask questions as well!
So it will probably a beta in two months. That's great news.
By the way, you don't need to apologize. You are one of the most active devs in ico threads. I always see some long answers to all posts from you. Thank you for that.
