"Straighten your feet. Stop slouching. Lift those shoulders!" Classic mum stuff.
Having (hopefully) progressed beyond the ever-correcting gaze of the maternal eye, you've probably got a vacancy in the department of 'Posture Corrector' - which is where Arki comes in.
In addition to the usual fitness-monitoring tricks of counting your steps and sleep patterns, the main focus of Arki's six-axis motion sensor is to improve your posture (which is a cue for you to you sit upright in your office chair) by measuring the way you walk.
Worn on your wrist, the band monitors a range of motions to determine how well you're walking - from how quickly you swing your arm to the rotation of your body. It's then able to determine bad habits you might be picking up, like walking long distances with a hand in your pocket or reading a smartphone for extended periods. As soon as you begin to hunch your shoulders or unbalance your gait, Arki will notify you with a small vibration.
In addition to pestering you on your morning commute, Arki looks to improve your posture with its accompanying app: wearing the band on your non-favoured wrist allows it to calculate how unbalanced your body is, providing stretches and body exercises to help even out your kinks.
Available with a range (and boy do we mean range) of interchangeable straps, you can order an Arki from its Kickstarter project page for around £64 ($99).
Then again, Christmas is only a month away - you could always wait for your mum to tell you everything wrong with your spine at six paces?
