Install PepCue on iPhone or Android.

PepCue ships on both the App Store and Google Play and is free to download. There is no trial to start, no card to enter, and no account to create before you can log your first dose.

On iPhone or iPad.

1. 01Open the App Store and search for PepCue, or scan the QR code from any install button on this site.
2. 02Tap Get, then confirm with Face ID, Touch ID, or your Apple Account password.
3. 03Open the app and work through onboarding: your units, your first compound, and whether you want reminders.
4. 04Allow notifications if you want dose reminders. You can change this later in iOS Settings, and the app works without it.

PepCue can read weight and body-composition data from Apple Health if you grant permission, which keeps progress charts current without retyping numbers. That permission is optional, is asked for separately, and can be revoked at any time from the Health app.

On Android.

1. 01Open Google Play and search for PepCue.
2. 02Tap Install, then Open.
3. 03Work through the same short onboarding.
4. 04Allow notifications when prompted. Android 13 and later asks for this explicitly, and reminders will not fire until you do.

If the app does not show up in search.

Store search is regional and can lag a release. The most reliable route is the direct store link behind any install button on this site, which opens your store app on the correct listing. If the listing reports that the app is unavailable in your country, that is a store-level restriction rather than something the app can work around.

Moving to a new phone.

Tracking data lives in an on-device database, not on our servers, so a fresh install starts empty unless your phone's own encrypted backup restores it. If you are changing devices deliberately, take an export from Settings before you wipe the old handset. Signing in does not by itself move your dose history across.
