2.0
2021-06-08
Release 2.0 represents multiple major changes, which are summarized here.
ACCURACY -- We've added a calibration process that takes you through 3 good vs. bad choices and calibrates the algorithm to your heart rhythms. This is now required to use the app and make choices -- it adds a lot to the accuracy of the app. Now you no longer need to enter your gender; the calibration steps will select the best algorithm for you based directly on your heart activity.
CONVENIENCE -- On iOS only, you can now connect to Choice Compass with a Polar or CorSense/Elite heartrate variability (HRV) monitor so you can think about your choices while you relax, and let Choice Compass do the rest. You can also choose to connect the old-fashioned way, with your finger on the web camera. Both work, and you can switch back and forth. But you do need to calibrate once before using each method.
DESIGN -- We've created an all-new updated design for iOS only, too many improvements to UX/UI to list. We also removed the need to create a userID.
SUPPORT -- Our new pop-ups, more informative error messages, help video and Help tab offers support and troubleshooting tips for most scenarios you are likely to experience, but let us know if there's something we didn't cover!

2015-04-14
Based on feedback and heart rate data from multiple testers, we improved the algorithms Choice Compass uses to both detect heartbeat rhythms and analyze these rhythms.
Because we found a gender difference in the data that seems likely to be produced by hormones, we now ask you to choose a gender before you use the app. If the previous version of the app was working well for you, choose "female" as your gender, because the new "female" algorithm is closest to the algorithm in the previous version. If the previous version of the app often chose what seemed like the wrong choice to you, choose "male" as your gender. Otherwise, just choose the gender that is closest to your own, and read Choice Compass Tips (in Settings) for more information about gender.
Added Twitter and Pinterest sharing buttons to enable you to easily share a Choice Compass session result.
Enhanced the documentation for how to achieve the best results and to further explain the science behind Choice Compass.

This version adds new functionality to help you have a more streamlined experience with Choice Compass:
A Practice tab allows you to experiment with finger placement to achieve optimal heartbeat detection.
Allows for restarting the session from the second choice if the first worked and the second didn't.
You can now start a session from History tab by sliding your finger left on the choice you wish to re-run, then selecting "Run."
Choice recording time has been shortened to 50 seconds, down from 60.
The tutorial is can now be zoomed, so it is easier to read.
Updated the Tutorial and Tips launched from the Settings tab.
Corrected minor typos and text display problems.
