Both of the iPhone features nominated as this week's Apps of the Week by an expert are free of charge, perhaps highlighting the affordability of the revolutionary device.
Jason Parker, writing a piece for CNET, explains the pair of tools should help people with their Christmas shopping, as the big day is now less than a month away.
The first of the recommended apps is Amazon Mobile, which allows consumers to shop and check prices via their mobile, in a similar style to the facilities on the firm's website.
"Apart from the usual searching and browsing, Amazon has given its app special mobile powers that make the most of the iPhone's features," states Mr Parker.
He goes on to name The Find as the next app to meet with his approval, with this function able to provide a list of prices from the web when a product's barcode is scanned by the phone.
Apple's latest version of the model, the iPhone 4, was released in the UK and US in June.
