iPhone app in beta
HiLo Baby on your iPhone.
The iPhone app is in a public beta on TestFlight, Apple's app for trying apps before they reach the App Store. Anyone with iOS 18 or later can join.
Join in two steps
- On your iPhone, install TestFlight (opens in a new tab) from the App Store.
- On the same iPhone, open the HiLo Baby beta (opens in a new tab) and tap Accept, then Install.
When the app reaches the App Store, install it from there and it replaces the beta. Your log stays. Tell us what breaks or feels slow at 3am: send a screenshot from TestFlight, or write to hello@hilo.baby.
Or wait for the App Store
We keep only the address, for that one email. Our privacy page says more.
