I think i may have a learning disorder. is there an app that you can use to diagnose yourself?

Doubt it.: Lds are diagnosed using standardized testing that measures ones overall intelligence (iq) and one's functional knowledge in the area of concern, e.g., reading or math. Ld requires a large discrepancy between the two--usually several grade levels--that is not a result of lack of exposure to the material. For young folk, schools provide that service; older folk need to fine a psychologist.
