ATOM speaks English, Spanish (Español), Korean (한국어), German (Deutsch), Japanese (日本語) and French (Français). Settings > Look and feel > Language. Pick one and your screens switch right away.
IT FOLLOWS YOUR LOGIN: your choice is saved to your account, so the website, the iPhone app and the Mac app all open in it next time you sign in. A brand new sign-in on a phone set to one of these languages starts in that language on its own.
WHAT STAYS ENGLISH ON PURPOSE: Money (settlements, deals, per diem, crew pay, expenses, budgets) stays in English so every number and money word means exactly one thing to the TM and the accountant. Anything a person typed (venue and hotel names, schedule items, notes, names) shows exactly as it was entered. Some newer or rarely used screens may still show English while the rest is translated.
HELP IN YOUR LANGUAGE: these help articles show in every one of these languages too. If an article was updated in English and its translation hasn't caught up yet, you'll see that one in English.
SPANISH: neutral Latin American Spanish, the way road crews talk (montaje, prueba de sonido, hoja del día; rider, backline and setlist stay as crews say them).
BETA: every language other than English is in beta. While you use one, a thin BETA strip sits under the header on every screen.
STUCK IN A LANGUAGE YOU CAN'T READ? That BETA strip always shows a flag button for each other language (on a phone, just the flag), and the English one always says English (US flag). One tap switches back, on every screen and on the sign-in screen, no Settings needed. If something is unsaved, ATOM asks first. The newest choice wins on all your devices.
A WORD LOOKS WRONG? Tap the small flag on that BETA strip (or next to Language in Settings) to open Report a wording problem. Say what you saw and what it should say. A person reviews every report; nothing you type changes the app by itself.
