“To date, there have been no further orders and no manufactured stock has been received in the UK. There is no change to the Company's expectation of receiving its first consignment of stock in the UK later this month.
“The company confirms that it has not recognised any revenue in respect of this order.”

CloudTag Track uses grade ECG (Electrocardiography) technology, allowing for accurate assessments of heart rate and energy expenditure and gives readings good enough for weight loss and health boosting programmes.
It can be worn on the wrist for daily tracking and on the chest during exercise. A one hour charge gives it life for three to five days.
Cloudtag said it is currently renewing its product brand names and is planning on announcing a new brand name in December.
