Sometimes you’re inner self doesn’t motivate you to act because it doesn’t feel this is the right path; and these instincts are usually right - the first thing you need to do is to validate the idea to yourself; would anyone buy or use this app?

In the education sector there are some easy ways to establish if organisations that largely depend on public funds would be willing to purchase and use your app - simply check on public procurement portals and look for tender opportunities and award notices to see if establishments are, or have in the past, sought after new technologies similar to you idea; if they have before, they certainly will again.

Once you have validated it to your inner voice; you can use the same argument to validate it to an angel investor. If the answer comes up negative; take all the best elements of your idea and combine it with another sector, or another need and do the same again. This way the worst case scenario is that you develop a habit of coming up with useful ideas that make your life and others easier.
