Absolutely, yes, but if you are writing your own apps rather than being paid to write apps for other people, there's a strong luck element as with any entrepreneurial activity. I have six apps out right now, of which just one accounts for 90% of my revenue. Rather than setting out to write apps, I think it's better to think about an app as merely a vehicle to deliver a service, a product, some unit of customer value, from you to your customers. If you have something to offer that is of high value, you can definitely make a lot of money from an app. If you don't, no matter how well designed and built the app is, it is likely to fail.

I think it is also good to keep in mind you won't get customers from app stores.

You need to get in contact with your customers in another way and then let them know where they can download your app.
