My recommendation would be to stay away from Quicken altogether. I had nothing but problems with both the desktop and mobile apps. To answer your question, it looks a lot like Mint, which I've never been crazy about either.
I haven't worked a lot with mint or mobile but my impression is that mobile is an offshoot of Mint but mobile falls short. If you are disappointed with Mint you will be less thrilled with the mobile app.
Hi. I am not sure about this. I am familiar with Mint but don't use it. I can tell you that the Quicken app shows cash accounts and your budget information. You can set up alerts and enter transactions into the cash accounts through the app. You have to manually sync Quicken to the Intuit cloud. This should be done automatically. I hope this helps.
