This gadget nudges you to stand tall

Another gadget is joining the wearable device space, and this one in particular is meant to help improve body posture in addition to tracking activity levels.

Lumo Lift, a small device that clasps on to a piece of clothing, tracks a user's body position and movement to prevent slouching.

The gadget works with a mobile app that lets consumers activate a "PowerUp" session to calculate how much time is spent in a proper posture. If they tend to hunch over, Lift will gently vibrate to remind them to pull their shoulders back.

If users don't want to receive vibrations anymore, they can switch out of PowerUp mode and Lift will passively track their posture, said Lumo Body Tech CEO Monisha Perkash.

Like many other wearable gadgets, such as the Fitbit Flex or the Jawbone UP, Lift can also track a user's activity and estimate calories burned throughout a day.

Lumo Lift is expected to be available in late spring for $99. A less expensive option that shoppers might want to consider is iPosture, which has a list price of $75.
