How can we help?

A) Create a new household (Household Owner)

Use this on the first device that will own and manage the household.

1. 1Install BillPlex on your device.
2. 2On the first screen, select “Create new household”.
3. 3Set up your household members and (optionally) a monthly budget.

B) Join an existing household (Second person)

The fastest way: the Household Owner shows a QR code, and you scan it with your phone’s camera. The two phones pair themselves over the same Wi-Fi.

1. 1On the Owner’s phone: open BillPlex → Settings → Sync. The QR code is already on screen — keep it open.
2. 2On your phone: open the Camera app and point it at that QR code.
3. 3Tap the BillPlex link that pops up. (If BillPlex isn’t installed yet, the App Store will open first — install it, then come back and scan again.)
4. 4You’re in. Both phones now share the same household.

Already have BillPlex open? Tap “Scan QR code” inside the app instead.→

C) Add more devices later

After the first pairing, the Household Owner can add more devices the same way — show a QR, scan, done.

1. 1On the Owner’s phone: open Settings → Sync — the QR is right there on the screen.
2. 2On the new device: open the Camera and scan the QR (or, inside BillPlex, tap “Scan QR code”).
3. 3The new device joins the household automatically.

A) First-time setup between two devices

Use this flow when two people want to share the same household for the first time.

1) Steps for the Household Owner

1. 1On the Household Owner’s phone, open BillPlex → Settings → Sync.
2. 2The QR code is already showing on that screen — keep it open while the other phone scans it.

2) Steps for the second person (Join existing household)

1. 1On the joining person’s phone, open the Camera and point it at the Owner’s QR.
2. 2Tap the BillPlex link that appears. (If BillPlex isn’t installed yet, install it from the App Store, then scan again.)
3. 3The two phones connect automatically over the same Wi-Fi — no Accept/Decline tap needed.

B) Adding more devices to the same household

1. 1The Household Owner opens Settings → Sync on their phone. The QR is shown there by default.
2. 2Each new device scans the QR with its Camera (or inside BillPlex, tap “Scan QR code”).
3. 3Each device joins the household automatically.

C) Syncing after initial setup

1. 1To sync updates, open Settings → Household Sync on the Household Owner’s device and on the devices you want to update.
2. 2On the Household Owner’s device, tap “Sync now” (or the equivalent sync action).
3. 3Keep the Household Sync screen open on all devices until the sync completes.

D) Removing / unpairing a device

1. 1On the Household Owner’s phone, open BillPlex → Settings → Sync.
2. 2Tap “Edit Household”, then remove the device you want to unpair from the list.
