The wearable device for sleep, reinvented 

Use this simple wearable device to:

  • fall asleep sooner for a longer night’s rest
  • take the perfect power nap
  • measure sleep with incredible accuracy


How it works

Sleep re-training

This gentle waking must be done within 60 seconds of entering your first, lightest stage of sleep. Only the incredible accuracy of Thim’s sleep tracking makes this possible.

The perfect powernap

how it works

You begin by placing Thim on any finger as you go to bed. Thim will detect when you have fallen asleep to the nearest minute. After 3-minutes of sleep, Thim wakes you up. You then fall asleep again and have another 3-minute sleep. Falling asleep again and again will condition your body to fall asleep sooner so you learn to fall asleep with ease.

You can customize the length of time spent re-training (more time or less time). We recommend you spend the first hour of your bedtime repeating this sleep re-training process. For example, if you go to bed at 10pm, conclude sleep re-training at 11pm.

the science

University Professor Leon Lack and his colleagues discovered a way to help people fall asleep 30 minutes sooner and sleep almost 70 minutes longer (Harris et al, 2007 & 2012).

They discovered you can train your body to fall asleep sooner; if you experience the sensation of falling asleep over and over again. They called this technique sleep re-training. This discovery paved the way for Thim.

In their research, participants fall asleep and after 3-minutes are woken up. This gave participants the sensation of falling asleep, repeatedly, over a short period of time. Falling asleep again and again conditioned participants to fall asleep sooner.

power napping module

Shift workers, elite athletes, executives and students use power-naps to increase energy, concentration and performance.

The perfect power-nap should last for 10 minutes. Sleeping too little or too much will leave you feeling groggy after your nap. Exactly 10 minutes ensures you wake up refreshed and reinvigorated.

Alarms can only countdown time. They are unable to know when you have entered stage 1 sleep to begin counting down from 10 minutes. Thim knows when you’ve fallen asleep – to the minute. Providing you the perfect power-nap for the first time.

thank you!

In just over 30 days, 1,000 people supported the development of this novel technology by contributing AUD $170,000. THIM is now in development and will be available from mid 2017.

In the meantime, you can pre-order THIM from Indiegogo and save $50.

The design journey

Our story

Professor Leon Lack conducted a University trial in 2007. He found a sleep training program which provided an increase in total sleep duration of almost 70 minutes.

Whilst the Professor experienced wonderful results in the lab, the expensive equipment meant most people could not afford access to this training. So the Professor started to prototype a simple, in-home solution.

Many design meetings later… here we are.

We collaborated with Professor Lack in 2012 to launch the Re-Timer Light Therapy Device. We’ve now sold more than 30,000 Re-Timer units worldwide and have won several design awards. We’re excited to do it all again.

We hope you’ll love this product as much as you loved our first.
