Frequently asked questions

Where are your web app developers located?

We are completely based in New York City. Our engineers are industry experts in developing web apps, responsive websites, and mobile apps. By having all our software developers located in NYC, we can provide unparalleled quality and collaboration with our clients.

What is the cost to build a web app / platform?

While the answer isn’t simple, but it isn’t as convoluted as many developers make it seem. Many web app developers will either build you a subpar app for a lower fee — you get what you pay for — or get you in the door at a low price only to invoice you 5x the original estimate down the road. What you rarely see is a realistic depiction of what an app costs and how that’s calculated. When you initiate a conversation with Utility and explain your ideas and goals, we walk you through what’s needed to execute and the exact costs to build a premium SaaS app.

How much time does it take to build a web app?

It all depends on what stage of your product roadmap you are on. Are you looking to build an MVP (minimum viable product) to show to potential investors or have a clear vision and product market fit already? All our engagements start with a crystal clear timeline based on agile development methodologies. Our clients get to see the work in progress builds every step of the way so you have full visibility of our engineering process. On average, time to build a premium quality web app ranges between 2 to 5 months depending on your feature set and roadmap.

How can I validate my web app idea?

The first step to validating your idea is doing the research to fully understand the market for the problem you’re trying to solve. Then, gather feedback by speaking to people who fit your target demographic. Customer feedback is crucial to be sure you’re solving the right problem to begin with. Next step is to build an MVP product that focuses on your core value prop -- and avoiding unnecessary features that would dilute their value. Our key goal is always to help clients validate their ideas quickly and cost effectively.

Web vs Mobile Apps: Which platform should I launch my product on?

If you are in the MVP phase, we always recommend starting with a single platform to prove out your hypothesis and control costs in the process. In order to decide which specific platform to go with, analyze your target audience. It all comes down to where your core demographic is going to be. That being said, there are millions of people on both platforms -- so you should be able to prove out your hypothesis on either. Another thing to keep in mind is technological restrictions depending on the complexity of your app. Our strategists help guide clients make this decision prior to getting started with design and development.
