Just when you thought you had a phone with every cool feature there is, out comes the Wellness Phone.
The prototype Wellness mobile phone from Japan's NTT DoCoMo was unveiled this week at the CEATEC electronics show outside Tokyo.
It can take your pulse, check your body fat, time your jogs and tell you if you have bad breath. It even assesses stress levels and inspires you with a pep talk.
The phone has an inbuilt motion sensor that detects body movement and calculates how many calories you burn.
The sensor can tell whether you're walking, running, climbing stairs, or resting, and counts the calories accordingly to tally daily totals.
Hold the phone with outstretched arms, and it turns into a mini body fat calculator. A sensor at the top of the phone takes your pulse from your fingertip.
Worried about bad breath? Use the phone's breathalyzer. Blow on a tiny hole on the side of the handset for about three seconds and it will tell you.
The Wellness phone also asks questions to assesses stress levels and offers advice.
At the show when a busy spokesman answered "Yes" to a series of questions - including "Do you feel lethargic?" and "Do you go to bed after midnight?" - a message appeared on the screen warning he was under a lot of stress.
"Don't worry, tomorrow's a fresh new day," the phone then flashed. "Keep your chin up!"
Japan has some of the world's most advanced cell phones, enabling users to surf the Web, check in at airports and play motion games.
DoCoMo has not set a release date or price for the Wellness phone. The Tokyo-based company's phones are not sold overseas.
