Nationly is an iOS app built for American expats, remote workers, and digital nomads who want to take advantage of the Foreign Earned Income Exclusion (FEIE). The app runs in the background to securely track your physical location and automatically generate accurate documentation to pass the IRS Physical Presence Test. Nationly even helps you export a pre-filled Form 2555 based on your actual location data, eliminating manual logs, spreadsheets, and guesswork.
