Thanks FatFork. Decent app. Would have been perfect if it wasn't limited to only 3 alerts and I could pair.
Yes, unfortunately there is a limitation in the free version. But for just 3.99 a month, which is the price for a 'Trader account' subscription, you are able to create up to 20 alerts with unlimited notification options. I understand that you're looking for a free solution, but if you don't find one, I don't think this price is that high considering what it offers.
I will update this thread with alternatives if I find any.
