Taking Calibrate to the next level


An opportunity to fill in the gaps and explore Calibrate's potential



The initial product

Calibrate came out of an earlier project, but due to prior constraints, I was unable to go into depth on research and app design. I've been given the opportunity to have an additional four weeks to expand on this project and fill in the gaps I want to explore further.


Why & What 

Female athletes need HRV* monitoring to optimize training and reduce injury. Calibrate provides the ability to measure and control HRV through cycle specific workouts, relaxation techniques, and recovery support.

To attain this, Calibrate uses a combination of a wearable (for the wrist) that measures heart rate variability and an app that tracks HRV data in addition to providing cycle specific training plans, food plans, and recovery support.

*HRV, also known as heart rate variability is the naturally occurring irregularity of our heartbeat. For example, your heart may beat 60 times in a minute, but the time between those beats isn't equal. Exercise physiologists have uncovered that HRV is a powerful tool in determining optimized training loads, especially in response to physiological stress. 


The Next Round of Calibrate

My main objectives in this next project iteration include:

1. Research (interviews, cultural probes)
2. Addressing gaps in current application design
3. Creating system maps (user journey mapping, device conceptual models)
4. Building out more complete app flows (based on design gaps and research insights)
4. Usability testing of new flows
5. Integrating insights into final design

I want to dive deeper into research by interviewing pro and amateur road and mountain bike racers. Bike racers tend to use a lot of "gadgets" and like to examine data, so they are a high level audience to research. Some of the areas I want to explore with these women include:

  • How they train
  • What tools they are currently using
  • How their menstrual cycle affects their training
  • Training wishes
  • Do they eat for their menstrual cycle
  • Altered training based on where they are in menstrual cycle
  • If they have irregular menstrual cycles

Interview Recruits

Research Methods

  • Interviews
  • Case Studies
  • Card Sorting
  • Journey Maps

Design Gaps
Areas I want to address in the current design include:

  • How to charge
  • Device feedback (lights + haptics)
  • When would feedback occur
  • Filling in gaps in user flow

Usability Testing
Areas I want to address in usability testing:

  • Minimal display face
  • Ease of navigation
  • Ability to understand feedback provided
  • Does HRV make sense
  • Does the scale of measurement make sense
