My wife and I recently found out we are expecting our first bio kiddo next year so one of the apps I use the most these days is What to Expect. Every week they update it with new graphics and information about how far along your baby is. I would LOVE to have this on my home screen as a constant reminder of what's to come and what's currently happening. It would act like a smart stack and scroll through important things like the size comparison of your baby, how many more weeks to go, developing areas during that particular week, and more. Ideally you could customize the info you'd like displayed. The illustrations are from their app - the fonts have been updated slightly from their current branding. This is a super simple, straight-forward widget that I hope is in the works!
