Crimsonandclover review for Rontar Ad Exchange: Free Ads

App is faulty. The math on it is consistently incorrect inflating the profit. For example it says I spent $140.74 on ads and made $115.60. And that my profit was $95.59. Um how is that possible? Despite numerous emails to Rontar they can't seem to answer the question and just go in circles. In addition the sales they say they made show up in Shopify as first time visitors so how exactly is that retargeting? No thanks.
