About Baby I/O

Baby I/O is for tracking your baby’s input (feeds) and output (poop/pee). It has these features: - One-time purchase NO SUBSCRIPTION FEE! - Track feeds - Track Breast Feeds specifics - Track bowel movements - Estimate next feed time - Track age in months, weeks, years—even days - Track multiple children at once - 2 units of measure to chose from: ml or oz - All the info you need for the pediatrician visits at your fingertips Some Back Story: Baby I/O is an app built by a new dad for his wife, a new mom, after she was frustrated with the existing baby tracking apps out there. Most apps were to hard to manage at 3am when she just wanted note that our baby ate and had a pee. Seeing these issues and trying out these apps myself I found other issues. Most of these apps require a subscription of sorts which, when you’re a new parent, you have already had to pay for a lot of things (i.e. diapers, formula, etc…) the last thing you want is to have to add an app subscription to all the other expenses. So, to solve these issues I went about designing and building an app that would be super easy to use. So when you’re half a sleep you can still use it with ease. Thus Baby I/O was born: an app with very simple controls, high contrast, big icons, and no subscription. These elements combine to make an app that even the sleepiest of parents are able to use with ease. This app allows you to see your baby’s input and output history at a glance. Have twins and you can track both in the same app no extra cost! *one-time purchase applies to base app in the future there maybe add-ons that will be an additional fee.
