A. Ensure that the object you are trying to scan is well-lit and clearly visible. Avoid scanning objects that are too small or have complex patterns. Try to hold your device steady and at the right distance from the object. If the app continues to struggle, consider updating the app to the latest version, as updates often include improvements to recognition algorithms.
B. If the app fails to recognize objects consistently, try resetting the app's cache. Go to your iPhone's Settings > General > iPhone Storage > Blippar > Offload App. This will remove the app but keep its documents and data. Reinstall the app from the App Store to see if this resolves the recognition issue.
