Its worth the dollar it costs.Its helped stay straight in my research and keeps me from burning through rune stones when enchanting. There are a few things that would make this app AMAZING. 1. Update quicker. Wrothgar stuff was added right before Thieves Guild released. 2. Add motifs into the app. For crafters, we like to keep track of motifs that we have obtained. It would be nice to mark off the ones we have. That way buying or trading, we can take a quick glance to make sure we are not trading or buying something we already have. Great work!
