Description by Ninja Number Written by the developer, not by AppBrain. Click to read.
Ninja Number is the Second Phone Number app that lets you choose how you want to communicate. Separate business and personal calls with a designated 2nd phone number. Our industry-leading technology is ‘Always On’ (and trusted for over 20 years by the biggest businesses in the world,) ensuring you have coverage 24/7/365! With Cloud Power and Artificial Intelligence, our app turns your phone into a Virtual Assistant.

Separate business and personal calls. Always know who’s calling when you use Ninja Number as your business phone number through Virtual PBX. When you return calls with the app, your Ninja Number will display, keeping your personal number private.

We’re excited to offer a 7-Day Free Trial for any user who signs up through our website - NinjaNumber.com

AI Auto Reply. Let Ninja Number handle customer questions for you! Customize questions and answers using AI-Powered Auto Reply, sit back and let your phone do the rest. Our best business app technology ensures your incoming texts and voicemails will be scanned for the questions you programmed and will text back with the answers you create.

Virtual Assistant Business App. Running a business is hard, so put your phone to work. Ninja Number organizes your SMS texts and voicemails, tags and filters your contacts and gives you detailed call tracking and analytics, so you don’t have to do it all.

Loop in team members. Get extra call coverage by looping in four team members. Easily link your Ninja Number to other devices so that when a call comes in, all phones ring. You’ll only ever pay for one subscription. We can also port or transfer numbers for you!

Live Ninjas On-Demand. Want call coverage even when you’re busy or in a meeting, and don’t want your VIP Calls going to Voicemail? With Live Ninjas On-Demand, a professional US-based live operator will answer your calls when you want them to. They’re trained to answer the phones like you would! Pay by the call and never miss another lead again.

Leads without calls. Ninja Number’s virtual phone system empowers you to communicate the way you want. Prefer business text messages? With AI Auto Reply and Cloud-Powered Visual Voicemail, you can text securely and so can your linked team members all in the same thread.

Ninja Number is a smart, protected Second Phone Line app with easy, simple setup. Choose a toll-free or local number to advertise to customers and clients. Want a toll-free vanity number?
