Great concept, but seems like they've given up – Quadro Review

There are a LOT of features listed as "coming soon". Do NOT buy this app in the hope that any features will be coming soon. The lack of updates from the company clearly indicates that nothing at all is coming soon, they are probably going to stop updating all together. You may find the features that exist to be enough, in which case you should go ahead and buy it, though it's unclear what will happen to your subscription if they give up. I understand being an independent developer is tough, but this lack of communication and broken promises, particularly at this price point, is unacceptable.
