At any give time,there are millions of businesses out there with unsolved problems and no software solutions to them. Some are niche, so not really commercially viable to pursue,while some are big enough to have really nice revenues. My advice is stop looking at the app stores, where 20 more calculator apps being added every day. Instead,talk to people outside software industry, ideally with those as far as possible from the tech sector. They will flood you with their problems. Listen carefully,then you'll have some good ideas to work on.
