First Days is a simple, private newborn tracker made by a new parent, for new parents.
 Being a new parent is its own challenge, the last thing you should need to worry about is a pen-and-paper spreadsheet to track the last time they ate and for how long, when they made a dirty diaper… 
In First Days, with just a tap, you can track all the essentials; - Feeding - Diapers - Sleep And for those times when baby is being extra spicy and it’s “all hands on deck”, you can use voice commands with Siri to add events or start a session. 
Reviewing your baby’s data in the app couldn’t be simpler, with clean, interactive charts. Privacy is a fundamental human right, and First Days was built with this principle front and center. - Your data syncs to your other devices automatically through your iCloud account - No signing up for yet-another online service; your iCloud *is* your account - No advertisements, in-app usage tracking, or any other invasive nonsense - Your data is YOURS; export all your baby’s data any time to a simple CSV format In addition to everything above, First Days comes loaded with great features. To name a few: - Customizable Feeding notifications - Daily and Weekly Smart Charts - Various accessibility features - Dark/Light mode - App Icon customization - Left-handed mode - Shortcuts integration To support ongoing development, First Days offers two subscription tiers that unlock even more. For the price of a few cups of coffee a year, the Premium subscription unlocks the following: - Caregiver Sharing! Securely share your baby’s profile with other caregivers, so they can view and log events for your baby as well. Share with a simple link, and revoke access any time. - 5 baby profiles (up from 2) - Smart Daily Goals that grow with your baby, based on recommendations from the American Academy of Pediatrics (aap.org) - More than 30 days of history visualized in-app (all data remains exportable with or without a subscription) - Trends and Insights, to help you see how your baby’s metrics are changing over time at a glance A Pro subscription unlocks all of the above, plus unlimited baby profiles.
