With a very reasonable cost the Fitbit Ultra is not likely to cause any health afflicting palpitations. Though you´re going to need to be pretty dedicated to the regime, and the reminders; the rewards are there for the taking. Better move now before I get told off again…

2012 is already being hailed as the year that fitness is going to be more affordable, accessible and apparently, more fun. You may already be a member of a gym or have workouts stashed on your smartphone – so why not join the revolution and take a look at the Fitbit Ultra, your own personal fitness trainer.

Why struggle to motivate yourself into using that old exercise bike languishing in the spare room when you can carry around a gadget the size of a packet of gum which incorporates a personal trainer, dietician and lifestyle coach?

The Fitbit Ultra clips onto your belt or pocket and takes a record of all of your activity in the course of a day. Incorporating an accelerometer, the Fitbit Ultra can log the number of steps you´ve taken, stairs climbed and miles walked or run. It also calculates the calories burnt performing these activities.

The Fitbit will even monitor how long you´ve been sitting still for, and issue appropriate enticements to get you moving again, such as ´vamos´, ´start moving´, and ´come on´. It would seem more likely that this feature would illicit the close attention of a hammer, which counts as an activity, though the Fitbit´s ability to record this will be somewhat reduced.

But the real fun starts when you upload all of this information using the included dock and USB cable to your private account on the Fitbit website. Once saved, you can track your activities over the coming days, weeks and months. Once you´ve added your personal details you can calculate your BMI, set fitness goals and even control your diet. If you also enter your meal information you can access the calories needed per day to achieve your targets.

And of course, there´s an app for fat – download the Fitbit app to your iPhone and you can access your details whilst on the move, or sitting down – as long as you don´t stay still for too long otherwise it´ll chastise you…

The Fitbit Ultra uses a MEMS 3-axis accelerometer that measures your motion patterns to tell you your calories burned, steps taken, distance traveled, and sleep quality. A built-in MEMS altimeter measures your vertical climb up stairs and hills.

Wireless sync

Fitbit Ultra - Portable Fitness Monitor syncs easily wirelessly to your base-station
The Fitbit Tracker syncs wirelessly to the base station (included in package) using an ultra-low power 2.4 GHz ANT radio transceiver.

Sync occurs automatically, anytime your Tracker is within about 15 feet of any base station and relatively motionless. The base station plugs into your Mac or PC’s USB port.

Syncing and uploading requires use of the Fitbit uploader application.


While we recommend you sync your data regularly, the Tracker can store up to seven days of detailed, minute-by-minute data, as long as it has minimum

battery power. It will also store daily totals (calories, distance, and steps) for the trailing 30 days, but without minute-by-minute stats.

Battery and power

The battery will last a minimum of 3 days between charges. The typical user’s experience is 5-7 days.

To check the battery level, place the Tracker on the base station and press the button. You can also see your battery level on your personal dashboard at, based on the last time you synced wirelessly.

To charge the battery, just put it on the base station. It takes about an hour to fully recharge from a low indicator.
