It's never too late to develop your first app. The most successful companies/apps are started by people with unique perspectives targeting like minded customers. As a 41 year old, you certainly have insights and perspectives that others do not.

Are you looking to develop the app, yourself, or are you considering bringing in a developer? Either route is possible, but the latter is much more time effective. There are plenty of programs designed to pair visionaries (like you) with technically minded people (developers). Some programs are even free or offer development a reduced rate.

You are off to the right start by posting on Clarity. I would strongly recommend having a conversation with mentors on this site or in local networking groups. If you would like to talk about getting off to the right start, I would love to help.

Best of luck and keep hustling!
