I have spent the last year learning how to create a web application and now that I am capable, I am having difficulty finding a utility that would be worth the time investment to create it. All the obvious ones exist and are controlled by a major player and I have no means to compete with my part time involvement. I'm not looking for 'the next big thing' as much as a usefull utility that could development into a livable income's worth of paying customers. Note: I am talking about a web only application. I am unfamiliar with android/iphone.
For UK market: Budgeting for people on benefits. It needs to be really simple to use, and cover benefits in (with dates) and money out. Have space for telephone numbers of various benefit offices and utility suppliers. Have reminders for when to pay. Have links to useful information - job centres and cv writing and CAB and etc.<p>Because of the limited funds of these users you'd monetise with ads.<p>---<p>"Mood Tracker" - there are lots of these. But yours would be better. In the UK we have something called IAPT - Improved Access to Psychological Therapies. These are first line therapies for people with mild to moderate depression, anxiety, etc. Your app would describe what CBT (cognitive behaviour therapy) is, and would help the user with some of the processes.
Million dollar question dude. Best way to find a good idea is to quietly examine problems you or people around you face, and come up with better solutions.
Study aids. Flash cards I could make on my desktop & use from my mobile browser at the bus stop or whatever. Teachers might pay to create decks. Sharing decks might be popular. Featured curriculum specific decks might make money.
