Deepinder Goyal has announced November 1 as the opening date for pre-orders of Temple, his new wearable hardware project. The device is designed to collect health-related signals from the head and is being developed as a new type of personal technology product.
The first batch will be handmade to order. Goyal says customers should expect delivery within three months of purchase. The company has not yet announced the price, the number of units available or the complete technical specifications.
What is Temple?

Temple is a head-worn device that uses optical sensors to track changes in blood flow towards the brain. The company refers to this measurement as BrainFlow.
The idea is to collect signals that may help users understand changes in their body over time. However, the company has not yet published enough independent evidence to establish what the device can reliably tell users or how its measurements should be interpreted.
That distinction matters. A wearable can collect data, but the data is only useful when the measurements are reliable and the information is explained clearly. A new health-related metric should not automatically be treated as proof of a medical condition or a measure of brain performance.
Pre-orders and delivery timeline
Temple Batch 01 pre-orders are scheduled to open on November 1. Each unit will be made to order, with delivery expected within three months of purchase.
The initial batch is planned in six colours. Real Jade, Deep Blue and Purple Funk have been described as limited editions. The company has not yet disclosed the total production quantity or final pricing.
The made-to-order approach suggests that the first batch will be limited. Customers should read the order terms carefully before paying, particularly the delivery estimates, cancellation rules and warranty conditions.
Since the full specifications and price are not yet public, buyers should avoid making a decision based only on promotional descriptions. More information about battery life, app support, sensor accuracy and long-term software support will be important before the product can be assessed fairly.
How it differs from a smartwatch
Most smartwatches focus on measurements such as heart rate, movement, sleep and exercise. Temple takes a different approach by placing its sensors on the head and focusing on changes in blood-flow signals.
That makes it an interesting hardware experiment, but it is not yet possible to say that it is more useful than a smartwatch or a smart ring. The products collect different signals, and their value depends on how accurately those signals are measured and what users can learn from them.
For everyday consumers, comfort will also matter. A head-worn device must be easy to wear, charge and use without becoming uncomfortable during normal activities.
Health claims need careful testing
Temple’s measurements should be viewed as experimental wellness information until the company provides stronger evidence for specific uses. Optical sensors can measure changes in light signals, but interpreting those signals requires careful testing.
Users should not rely on an experimental wearable to diagnose a medical condition, change medication or replace advice from a healthcare professional. Any concerning symptoms should be discussed with a qualified medical professional.
Privacy is another important issue. A wearable that collects health-related data should clearly explain how information is stored, who can access it and whether it is shared with other services.
What to watch before buying
Before pre-orders open, buyers should look for the final price, a complete specification sheet, the companion app’s features, battery-life details and clear warranty information.
Independent reviews will also be important. They can help show whether the device is comfortable, whether its measurements are consistent and whether the app offers useful information instead of simply presenting unfamiliar scores.

Passionategeekz Take
Temple is an unusual wearable that could bring a new approach to personal health tracking. But the important questions remain unanswered: how much it will cost, how accurate its measurements are and what users can reliably learn from them. The November 1 pre-order date is a milestone, but buyers should wait for detailed specifications and independent testing before judging its value.
