Begin market research for your appIf you do decide to monetize your new app, your work is cut out for you. You can easily find in-depth guides and videos with tips on selling your app, but you'll want to do some market research first, including your target demographics, competitor apps, and the price you should charge. One common piece of advice is to go to related subreddits and ask people to test out your app, tell you how much they’d pay for it, and give feedback. Any advantage over existing products is a plus.
