1. Friends and family will always tell you your app is good. You need to do customer validation. http://momtestbook.com/ http://momtestbook.com/ is a good book on the subject. 2. Do some quick math: how many copies will you need to sell to cover your living expenses? If this is a mobile app you sell for $5, it's going to be a huge number. 3. How are you at marketing? If you have no experience at marketing you're basically relying on luck. And this is small business marketing, not "I'm a giant company doing branding" marketing, which is all you're likely to learn in school. If you're just graduating you probably have few responsibilities. So find a job that isn't all-consuming, learn marketing and work on your app in your spare time.
