The flok app is designed by and for those with the following disorders: Classical HCU, MSUD, Organic Acidemias, PKU, Tyrosinemia, and Urea Cycle Disorders. These initial members of the flok share a common treatment: the low-protein diet. If your condition isn't represented, you can request it be included in future versions of the flok app by using the chat bot on flok.org, or by downloading the app and clicking the "don't see your condition?" link during setup.
