Hi! This is my first ever product launch and it has been so fulfilling to work on a personal project that allowed me to use my brain and flex my creativity. I really appreciate anyone willing to take a look and give some feedback! It has been a labor of love. I am a Personal Finance nerd at heart and on the hard days at work, I can spend time staring at retirement calculations day dreaming about when I can delete work email off of my phone once and for all. When I would go to some of the free sites, sometimes it felt like I was giving my most personal financial data over to a site to scrape my info. Slingshot runs locally on your device and financial details are 100% private. I am most particularly interested in feedback on my 301 "Pro" (free) model. The math is much more involved, but I've documented it for anyone to throw stones at! All results and assumptions are printable or downloadable to CSV. You can also enable Local Storage (off by default) to keep your sessions live on a device. Thank you so much for looking!
