It’s a clone of Sideline – SmartLine Second Phone Number Review

It works well enough. It does have a leg up on most of the “second number” apps out there because it uses the underlying phone carrier, and is not VoIP. Let’s face it, even today, VoIP over mobile data is still pretty bad, and if you’re trying to not sound like a cheapskate to your customers, that matters. That said, it’s basically a clone of the Sideline app which has been around for years, and does not have any killer features to recommend it over its more mature competition. Maybe competition will drive both to accelerate feature development. I hope the developer realizes that they’re also in competition with carriers offering multiple numbers per device now. Calls, texts, and voicemail are not features—they’re the price of admission. That doesn’t leave this app with an advantage at present.
