Google adwords for iOS
Do you know that Google adwords has a separate app for iOS? This is probably the best thing that can happen for iOS device users, especially those who want to use Google ads to power their business.
This app makes it possible to do a ton of things. On this app, you can see adwords applications, change your bids, search for the most complicated keywords such as "management + adwords + analytics + site + know + performance" and still get meaningful results, manage your ad campaigns and even act on the many recommendations given by adwords from time to time! The most salient aspect is the visual appealing reports that this tool generates for you.
However, you won't be able to create new ad campaigns or add new keywords to an existing campaign as of now. It could change in the subsequent versions though.
