Q) What is the difference between a smart alarm and normal alarm?

Normal Alarm:

A morning alarm that will wake you at a time you select. The alarm is an ascending vibration.

Smart Alarm:

If you set your Smart Alarm for 8:00am, THIM will wake you up sometime between 7:30-8:00. THIM will select your lightest sleep stage to alarm.

The Smart Alarm can be used in conjunction with the Sleep Re-training feature. That is, you may undertake 1-hour of sleep re-training between 10pm and 11pm, and then use your Smart Alarm in the morning to wake up.

Q) Do I need to plug my THIM into my smart device (phone) to sync the data with the application?

Answer: No. All THIM data and information wirelessly syncs with the smartphone via Bluetooth LE (Low Energy) technology.

Q) What is vibration calibration and how do I do it?

Answer: When you run a sleep re-training program, THIM will emit a vibration every ~30 seconds. You will let the ring know you have felt the vibration with a single tap of your finger when you feel this vibration. This is how THIM knows you are still awake. This vibration should be subtle enough for you to feel it when awake, but not too strong that it will wake you when you are asleep.

To get the vibration customised to your own sense of touch, you need to calibrate your THIM.

To get started, tap on Calibrate your THIM. When setting up the vibration calibration, THIM will cycle through 12 pre-set vibration levels in ascending order. Tap the Acknowledge button on your phone screen in the app when you feel your preferred vibration level.

Answer: No. There is no ON/OFF switch for THIM. When THIM is not in use it will enter a low power state to conserve battery.

Q) How do I sync my sleep data?

Answer: Select the Sync App with THIM button on the home screen.

Note: You must be connected to THIM and have completed a sleep program in the app to have data to sync.

THIM is vibrating before I fall asleep

If you feel that the vibration is sounding before you fall asleep, there are two possibilities:

1) THIM is not detecting your finger tap. Tapping your index finger (with THIM on it) against your thumb is the optimal tap for THIM

2) You have actually entered your first stage of sleep (the mind and body begin to ‘slow down,’ causing us to feel drowsy and relaxed. This is when your mind starts to wander). Your sleep time is only very brief during sleep re-training. As a result you may feel like you did not fall asleep at all. Trials at Flinders University have shown that people have entered sleep even though they may verbally report not doing so.

I cannot see my sleep data

You can see your sleep data by completing the following steps. Tip: you must be connected to the internet to see sleep data. 

1. Tap the green Sync app with THIM button from the home screen (pictured below). If successful, you will see Getting recent data from THIM on the button.

Tip: you must be connected to THIM first and have completed a sleep program. You can see your bluetooth connection status by visiting the settings page.


2.  Once downloaded you will see the previously completed programs on the home screen in most recent order first. There is a summary on the button and you can tap on the button to see more details.

My THIM is still not working. How do I reset my device?

You can perform a device re-set by inserting and then removing the USB power cable 3 times in 10 seconds. Ensure the USB cable is plugged into power first. 

I cannot see the Settings menu

The settings icon is located on the home screen (pictured below) in the bottom right of the screen. Selecting this icon will take you to the details on your THIM, but only when you are connected to the ring. This page displays bluetooth connection status and battery level.



Q) What is the finger band made of?

Answer: All four finger bands are made of 100% silicone. Silicone is a highly stable material and therefore the most stable material to use to avoid skin reactions for persons with sensitive skin.

Q) Can I replace the battery in THIM?

Answer: No. THIM has a non-replaceable battery.

Q) How should I store THIM

Answer: If you are not planning on using your THIM for an extended period, before placing it away in storage to prolong the life of the battery ensure you fully charge your THIM. Periodically charge THIM once every six months to ensure optimum battery life performance. Before using THIM if you haven’t for a while make sure you fully charge the battery.

Q) How long will THIM’s battery last on a single charge?

Answer: This depends on the features you load onto THIM. For most users, there will be sufficient battery for up to 3 nights of use before charging is required. If the battery is below 30%, you should charge your THIM before loading any sleep programs.

Q) How long does it take to charge the battery?

Answer: It takes approximately 2 hours to fully charge an empty battery.  

Q) What is the stop button in the sleep program?

Answer: This will stop the current program that THIM is performing. THIM will glow red when you select STOP. This will also erase any data for that program. To continue the program, tap OK.
