How a Top-Rated Business App -TapeACall- Was Built on Zang in Record Time

TelTech is a telecom-focused tech company that creates inventive Web and mobile communication apps. Its products are innovative yet practical, and exactly what people really want—whether they know it yet or not. Its latest release is WhoApp, a free service that transforms unknown phone numbers into names, faces and addresses so you’ll never wonder “Who’s calling?” again.

Since the company’s inception, TelTech employees have always been passionate about conceiving of and designing cutting-edge communication apps. However, as the business grew, so did a sense of frustration with the time-consuming development process. It eventually became clear that the heavy focus on building app architecture was taking creative time away, hampering productivity.

The Problem

The trouble began when TelTech’s TapeACall app, which records iPhone calls, started taking off. Of course, that wasn’t a problem at first—it was reason to celebrate. But the increased demand meant scaling the product, and it wasn’t long before the TelTech team knew they needed help.

The theory behind TapeACall was fairly simple. It uses an additional phone line to record iPhone calls, since Apple prevents recordings for privacy and legal reasons. When the app was originally built, the developers used a combination of off-the-shelf services and their own in-house tools to create a solution. Scaling up using those tools, however, proved to be more cumbersome than they’d expected.

Doing the re-development themselves promised to be a labor-intensive task—one that could take months of work and didn’t leverage the team’s core competencies. And enlisting the help of a third-party provider at this point wasn’t ideal, either. TelTech had worked with third-party API providers in the past, and while the solutions ultimately worked, it was always a struggle to make those tools fit perfectly with their products. In this case, neither alternative seemed like a good option.

As TelTech’s Ethan Garr, vice president of products, explains, “We’re a company focused on growth. Growth for us is in building new, innovative communication apps, not spending months and months building infrastructure to support that.”


The Solution

TelTech became aware of Zang at this critical juncture of the TapeACall re-development process. Many of Zang’s communication-related tools were just what the team needed to build TapeACall, including Zang’s tools for call recording, caller identification and notification. On top of that, the build process was much less time-intensive than it would have been otherwise. The result is an easy-to-use app: Users open the app, and Zang places a call to the recording line, which then begins recording the call. TapeACall is now one of the top-selling apps in the business app store.


“Zang is a partner”

Since TapeACall, TelTech has used Zang tools for numerous apps. Zang was designed to guide users smoothly through the application development process—no expert programming skills required—so it was exceptionally easy for TelTech developers to use. In the case of TapeACall, the platform enabled the team to get the product to market much faster than originally anticipated, saving five to seven months of developer time.

The team was also thrilled to develop a great working relationship with the people at Zang, and now considers them partners. “At Zang, we have relationships with people who understand our specific needs,” says Garr. “Where it makes sense for us to adapt to a Zang tool we will, but when Zang can adapt the tool to us, that’s when we get the kind of personalized attention that we need.” Developers at Zang continually work with the TelTech team to determine the best ways to use Zang tools in their apps, and, in some cases, Zang adjusts its tools to fit TelTech’s needs.
