This idea is very intriguing. I believe the product is very doable if you have the appropriate tech resources and the right team. I'm unsure of what the target market may be for this application? Middle-aged individuals? And are you planning to make this free because I'm not too sure people will be willing to pay for this unless it has more attractive features. I would love to talk further about this and help you brainstorm some concepts + viable business models. Ping me!
