Dedicated research and development of cryonics monitoring systems


Our custom solution has <1hr
alarm time, a big improvement over other custom solutions

We seek out solutions that can improve upon exiting options in terms of speed and reliabiliy
Analyzing Motion
You move your wrist 1000s of times per day, and over 50 times at night. While other sensors like heart rate sensors may give false negative readings, motion sensors are accurate in detecting a problem
Continuous Improvement
We use a data-driven approach to improvements in usability, closely measuring error rates and other usability issues, to gain insight into where we can improve
Good Battery Life
Unfortunately, many common
sensor devices, such as the Apple Watch, have a battery life of less than 1 day

Our flagship solution has over 3 days of battery life.
We evaluate other solutions on the basis of average use-case battery life
Devices Evaluated
We've evaluated over 8 off-the-shelf sensor devices for suitability for the cryonics alarm monitoring.
Optimizing for Best, Worst and Average

The best, worst and average times for an alarm are all important. Cryonics Monitoring improves on the worst time by over 80%, coming in at only 2 hours.

See our 'Reviews' for important details about these comparisons, including comparison with Gene Shaver's Fitbit Sense implementation.

Cryonics Monitoring is a non-profit organization founded by Nikki Olson for the purpose of research and development of cryonics monitoring systems. Nikki started working on cryonics monitoring solutions in late 2020 and developed exploratory prototypes for consumer devices such as the Apple Watch, Fitbit, and Android Watches (WearOS). From September 2022 to May 2023, she developed a more complete monitoring system for the Fitbit Sense with help from software developer Philipp Bartels, who created the system's Web UI component. Philipp also contributed research on ballistocardiography (BCG) sensor technology and had editorial involvement in the publishing of the organization's research, review and media content.

The organization shifted direction when the Fitbit Sense was discontinued in late spring 2023, leading to the decision to instead develop a custom system tailored for cryonics monitoring. Nikki, Jordan, and Michael now work enthusiastically on developing a custom smart ring for cryonics. Stay updated on our cryonics monitoring project here.
