poor performance – Marksta Review

I was hopeful but it's a waste of time and money. SLOWWWEER than molasses and then gets stuck. I have no problems with my other apps or speed on my iPad..issue is not on my end. Would be nice if you fixed this to work as you say it does and show in your demo. But, actions are what I care about and PAID FOR. Refund please or i'll call this a scam & false advertising.
Review by fix it or refund me on Marksta.
