SmartLine

SmartLine is a mobile app that gives a smartphone a second phone number for business. It separates work calls from personal ones, so the owner can look more professional to customers. The company argues that a professional impression leads to more business. The app has an account area where existing users sign in, and a recovery route for a forgotten username or password.

What SmartLine offers

• Second number — a business line on the same phone.
• Call separation — keeps business and personal calls apart.
• Account sign-in — users log in with an account or a linked sign-in service.

Who it works with

Self-employed people and small businesses who use their own mobile for work calls are the likely users.
