- Add it to your Home Screen to use it like an app
- Updates itself every time it opens
Installing the early access app
- On your Android phone, tap Download the app above.
- Open the downloaded file. If Android asks, allow your browser to install apps — you can switch this off again afterwards.
- Tap Install, then open Lowkei.
Only install Lowkei from this site. If you got the file anywhere else, delete it and download it here.
On iPhone
- Open getlowkei.vercel.app/app in Safari.
- Tap the Share button, then Add to Home Screen, then Add.
- Open Lowkei from your Home Screen. It runs full screen, like any other app.
On iPhone, what you write is kept in Safari’s storage on your phone — not uploaded, but not encrypted the way the Android app is, so keep a passcode on your phone. Adding Lowkei to your Home Screen keeps Safari from clearing it. Voice and Health Connect are Android-only.
What you’ll need
- An Android phone running Android 8.0 or newer.
- To read sleep, steps or heart rate: Health Connect, which is built into Android 14 and available from the Play Store for older versions. It’s optional.
- To use the Mirror: an internet connection. Everything else works offline.
- On iPhone: iOS 17 or newer, and Safari.
