Hi,
Next to sleep quality, it would be nice to be able to track on a daily basis in the same way the following measure:
- energy level: Happy smiley = High energy level, Grumpy smiley = low energy level
- stress level: Happy smiley = low stress level, Grumpy smiley = high level
- self esteem level: Happy smiley = high self esteem level, Grumpy smiley = low self esteem level
Related to other algorithm, it could be a way to signal possible depression, burn out or other dysfunction of a person.
Kind regards,
