Install Marrow and send your first note
Marrow is an app for iPhone and Android, in Beta. Install it, sign in with your email and a code, and send it the last business card you are still carrying.
Marrow is also on Telegram: @UseMarrowBot. The app and Telegram share one conversation.
Marrow needs iOS 15.1 or later, or Android 7 or later1. It runs on phones, not tablets. Marrow is in Beta.
Four steps from install to your first saved person
Sign in with your email and the six digit code Marrow sends. There is no password.

Allow what you need on the first screen, or wait until a feature asks.

Hold the microphone and say who you met, or send a photo of their card.

Read the reply: it says what was saved, so a misheard name shows at once.

After you install
- Free for 30 days, no card: 100 messages a day, 100 lookups, 100 voice notes and 100 photos.
- Choose Marrow’s language in Settings. English and Arabic are at launch quality; French, Spanish and Chinese are in beta.
- The app opens your contacts only when you tap Import or switch on the contacts writer in Settings, and your calendar only when you switch on the calendar writer.
- Nothing is sold inside the app. You subscribe on the web from the pricing page.
Already on Telegram? Link it in Settings, Telegram, and the app and the chat become one conversation.
