I’m working on https://creditcardchecklist.com It lets you keep track of your credit cards and which perks you have used and when the annual fee is going to hit. I often forget to use up the perk before it expires. You don’t even need an account buts you get notified if you make one. Also it’s free!

I also am working on https://trypixie.com - a way to employee your kids legally. It gets money into their Roth and saves you taxable income all while teaching them about working.
