Rating symptoms on a numerical scale seems easy, but it can be harder than it appears. How much did it hurt when you stubbed your toe? Was it a two out of 10? A four? How often do you wake up at night? Twice, three times? Regularly? Rarely?

These imprecise, self-reported scales can be found throughout medicine, even relating to diseases where the stakes are higher than a bruised toenail. Koneksa, founded in 2013, is working toward discovering and validating clinical biomarkers. That process begins by looking to turn those analog scales digital — and improve them in the process.
