Why Choose Zco?

Frequently Asked Questions

Get answers to some of the most commonly asked questions below!

Where is Zco Located?
Zco is headquartered in Nashua, New Hampshire at Trafalgar Square. We have satellite offices in New York, NY and Boston, Massachusetts as well.

How are apps distributed?
We’re experts in the app store submission process, having submitted hundreds of apps for hundreds of clients to the various consumer download services. These include the Apple iTunes App Store, Google Play for Android and private distribution for enterprise applications.

How is my mobile app idea protected?

One of the very first steps after you contact us is the signing of a non-disclosure agreement (NDA) by both Zco and you, the prospective client. This protects both parties since we’ll be working very closely together. Once development is completed and signed off by you, the app and all its source code and intellectual property belong to you.

What mobile platforms do you develop for?
We develop apps for the iOS and Android platforms. These can be native applications, hybrid applications, or progressive web apps. You can learn more about these options on our Mobile App Development page.

What is the average cost and time to build a mobile app?
An average app project might cost about $30,000, with functionality and complexity raising or lowering the price accordingly. The development time can be around 3-9 months. The more clearly you’ve defined your idea and how it will work as an app, the more closely we can estimate a time frame.

Will you develop my app for profit share?
Zco works strictly as a developer for hire. We do not participate in any revenue splits or percentage agreements. That means while you shoulder development costs, you own your app free and clear, including source code and intellectual property.
