At the top left, the form shows the contact's picture. For contacts without a photo, the initials follow the first and last name or the company as you type. A photo cannot be uploaded, changed or removed in the app.
Name and company
- Vorname (First name): text, at most 120 characters.
- Nachname (Last name): text, at most 120 characters. Determines the sort order in the list.
- Firma (Company): text, at most 200 characters.

Phone

- In each row, the type of number on the left, the Telefonnummer (Phone number) field on the right (at most 60 characters).
- Number type: Mobil (Mobile), Arbeit (Work), Privat (Home), Zentrale (Company main), Fax Arbeit (Work fax), Fax privat (Home fax), Pager, Andere (Other). If an existing number has another type (for example Assistenz, Assistant), it remains available in the selection as well.
- For a new contact, the first row is set to Mobil (Mobile).
- Telefon hinzufügen (Add phone): adds a row and suggests the first type still free from Mobile, Work, Home. At most 10 numbers; after that the button disappears.
- Telefon entfernen (Remove phone, minus icon on the left): removes the row.
- The app does not save empty rows.
The order of the numbers matters: Anrufen (Call) in the card and in the menu dials the first number.
Email
- One field per row for an address (placeholder „name@beispiel.de“). There is no type such as personal or business.
- The first address is the preferred one; E-Mail (Email) in the card and E-Mail schreiben (Write email) in the menu use it, and in the vCard export it is marked as preferred.
- E-Mail hinzufügen (Add email) / E-Mail entfernen (Remove email): at most 10 addresses.
- When you leave the field, the app checks the address; on an error, Keine gültige E-Mail-Adresse (Not a valid email address) appears below it.

When creating a contact, the app warns if an address is already saved: Diese Adresse ist bereits gespeichert bei [Name]. (This address is already saved for [Name].) The Eintrag anzeigen (Show entry) button opens the existing contact. Saving is still possible.
Address

- Choose Adresse hinzufügen (Add address). Arbeit (Work) is suggested first, then Privat (Home), then Andere (Other).
