Fix MyFitnessPal Barcode Scanner Not Working Easily

The barcode scanner in MyFitnessPal is a powerful tool for quickly logging your meals and tracking your nutritional intake. However, when the scanner stops working, it can throw a wrench in your daily routine, making it more challenging to keep up with your diet goals. If you’re dealing with this issue, don’t worry—there are several steps you can take to troubleshoot and fix the problem. These my guide will walk you through some unique and detailed solutions to get your barcode scanner up and running again.

Check Your Camera Permissions

The barcode scanner in MyFitnessPal relies on your device’s camera to function. If the app doesn’t have the necessary permissions, the scanner won’t work.

• Check Permissions on iOS:
  1. Go to Settings on your iPhone.
  2. Scroll down and select MyFitnessPal.
  3. Tap Camera and ensure it’s toggled on.
• Check Permissions on Android:
  1. Open Settings on your Android device.
  2. Navigate to Apps or App Manager.
  3. Find and tap on MyFitnessPal.
  4. Go to Permissions and ensure the camera is enabled.

Personal Tip: After enabling camera permissions, close and reopen the MyFitnessPal app to ensure the changes take effect. If you recently updated your operating system, rechecking these settings can solve any permissions reset during the update.

Update the MyFitnessPal App if Barcode Scanner Still Not Working

Sometimes, issues with the barcode scanner can be due to bugs in the app that have since been fixed in newer versions.

• How to Update on iOS:
  1. Open the App Store.
  2. Tap on your profile icon in the upper right corner.
  3. Scroll down to see available updates and find MyFitnessPal.
  4. Tap Update if an update is available.
• How to Update on Android:
  1. Open the Google Play Store.
  2. Tap the Menu icon (three horizontal lines) and select My apps & games.
  3. Find MyFitnessPal in the list and tap Update if an update is available.

Personal Tip: Set your apps to update automatically to avoid missing important updates that could fix bugs or improve functionality. If you prefer manual updates, check for updates weekly.

Clear App Cache and Data

Corrupted cache files or stored data can interfere with the performance of MyFitnessPal, including the barcode scanner.

• Clear Cache on iOS:
  • Unfortunately, iOS doesn’t offer a straightforward way to clear app cache. The best approach is to delete and reinstall the app.
• Clear Cache and Data on Android:
  1. Open Settings.
  2. Go to Apps or App Manager.
  3. Find MyFitnessPal and tap on it.
  4. Select Storage, then tap Clear Cache.
  5. If the problem persists, try Clear Data (note: this will log you out and reset the app to its default settings).

Personal Tip: Clearing the cache should be your first step before clearing data, as clearing data will remove your preferences and require you to log back into the app. Use Clear Data only as a last resort.

Test the Barcode Scanner in Different Lighting

The accuracy of the barcode scanner can be affected by lighting conditions. Poor lighting can make it difficult for the scanner to read barcodes correctly.

• Use Natural Light: Whenever possible, scan barcodes in well-lit areas with natural light, which is less likely to create shadows or glare.
• Avoid Direct Sunlight: Direct sunlight can cause glare that interferes with the camera’s ability to focus on the barcode. Instead, find a spot with indirect light.

Personal Tip: If you’re indoors, try scanning near a window during the day or under bright, even artificial lighting. Experiment with different angles if the scanner struggles to read a barcode.

Restart Your Device

A simple device restart can often fix minor software glitches that might be affecting the barcode scanner.

• How to Restart on iOS:
  1. Press and hold the Side button and either Volume button until the power off slider appears.
  2. Drag the slider to turn off your device.
  3. After your device turns off, press and hold the Side button again until you see the Apple logo.
• How to Restart on Android:
  1. Press and hold the Power button.
  2. Tap Restart (or Power off depending on your device).
  3. If you select Power off, press and hold the Power button again to turn the device back on.

Personal Tip: Make a habit of restarting your device at least once a week to clear out any temporary bugs and ensure smooth operation of all apps, including MyFitnessPal.

Ensure the Barcode Is Legible

Sometimes the problem isn’t with the scanner but with the barcode itself.

• Check for Damage: Look at the barcode you’re trying to scan. If it’s smudged, torn, or partially missing, the scanner won’t be able to read it properly.
• Clean the Lens: If your camera lens is dirty, it can affect the scanner’s performance. Gently wipe the lens with a soft, microfiber cloth to remove any smudges or dust.

Personal Tip: For damaged barcodes, try manually entering the barcode number in the app. MyFitnessPal allows you to input the numbers below the barcode if the scanner can’t read it.

Reinstall the MyFitnessPal App

If all else fails, reinstalling the app can often resolve more stubborn issues.

• How to Reinstall on iOS:
  1. Press and hold the MyFitnessPal app icon until the options menu appears.
  2. Tap Remove App, then Delete App.
  3. Go to the App Store, search for MyFitnessPal, and reinstall it.
• How to Reinstall on Android:
  1. Press and hold the MyFitnessPal app icon, then drag it to the Uninstall option that appears.
  2. Go to the Google Play Store, search for MyFitnessPal, and reinstall it.

Personal Tip: Before reinstalling, make sure your data is backed up to your MyFitnessPal account (not stored locally) so you can easily restore your progress after reinstalling.

Contact MyFitnessPal Support

If the barcode scanner still isn’t working after trying these steps, there may be a more complex issue at play.

• Submit a Support Request: Go to the MyFitnessPal website or app, navigate to the Help section, and submit a support request explaining your issue. Be sure to include details like your device model, operating system version, and the steps you’ve already taken to troubleshoot.
• Check Community Forums: The MyFitnessPal community forums can be a great resource for finding solutions from other users who have experienced similar issues.

Personal Tip: When contacting support, be as detailed as possible. Include screenshots or screen recordings if you can—this helps the support team diagnose and resolve the issue more efficiently.
