Have a question?


1) If I purchase early access, when do I get it?

MaddCog has sensor stock ready to send. Sensors are sent worldwide using DHL. Once received, you can start using it immediately. You will get access to ongoing app updates, and will be sent the new MaddCog headband when available.

2) Are these sensors safe to wear?

The sensors are safe to wear. They use standard BLE to send the data, just like a smartwatch or wireless headphones. The EEG simply detects activity from skin touch, and the MaddCog headband uses optimal sensors to measure heart rate variability, just like many smartwatches do.

3) Is this accurate?

All the sensor hardware is accurate, and we can supply published research if requests. Additionally, MaddCog's measures of fatigue, flow and performance have been developed from hundreds of hours of controlled trials to ensure validity.

4) Why is this only $20?

MaddCog is currently in early access. We are not looking to profit, and the hardware alone costs us several hundred dollars. Rather we charge $20 for access to ensure early access users are committed and have a serious interest in the product. We are after dedicated users who are interested in the product and want to product useful feedback.
