About

I’m Joaquin Marticorena, an independent developer. I design and build iPhone and Apple Watch apps, mostly about health and habits: what we eat, how we sleep and how our body clock works.

The glycemic index guides and charts on this site grew out of building Glycemic Index AI Food Scanner: I wanted reliable, checkable values, so I built the database from the international glycemic index tables and USDA data. The methodology explains every step.

I am not a doctor or dietitian. Information on this site is educational; for decisions about your health, talk to a professional.
