Logging In on Mobile

All Users

There are two ways to log in on the mobile app: email/password or login barcode.

Email and Password

  1. Open the mobile app in your browser.
  2. Enter your email address and password.
  3. Tap Sign In.

Login Barcode (Faster)

If typing on a phone is inconvenient (especially with gloves in a warehouse), use the login barcode method. See Login Barcode below.

Tip:

The mobile app remembers your session for 30 days. You should not need to log in every time unless you explicitly log out or clear your browser data.

Login Barcode

All Users

The login barcode lets you sign in to the mobile app by scanning a QR code from your desktop session. This is faster than typing credentials, especially for shared devices.

How to Use Login Barcode

  1. On your desktop computer, log in to ListerLeo normally.
  2. Click your profile avatar in the top right corner.
  3. Click Mobile Login QR.
  4. A QR code appears on screen. It is valid for 5 minutes.
  5. On your phone, open the ListerLeo mobile app.
  6. On the login page, tap Scan Login Code.
  7. Point your camera at the QR code on your desktop screen.
  8. You are logged in instantly.

Important:

Login QR codes expire after 5 minutes and can only be used once. If the code expires, generate a new one from your desktop profile menu.

Scanning Items on Mobile

Scanner

The mobile scanning interface uses your phone's rear camera to read barcodes. It supports UPC, EAN, ISBN, Amazon ASIN, FnSKU, Code 128, and QR codes.

Tip:

Hold your phone about 6-8 inches from the barcode for best results. If the camera has trouble focusing, try moving slightly closer or further away. Good lighting significantly improves scan speed.
