Google Lookout app

With Lookout you can have text recognized and read out, request product information based on the barcode, recognize objects in your environment, recognize currency (choice of three currencies), describe a photo and recognize colors.
The reading functions are good with a handy help when photographing a document, but the language of the speech is not automatically set to the language of the recognized text.
The function to recognize products based on barcode is quite good.
The recognition of banknotes works well, even if there is more than one note in view. The number of currencies is limited to three (including the euro)
Lookout can keep a history for most functions, so you can return to previously recognized text or objects.
You can download Lookout for your Android phone for free from the Google Play Store.
