  • I'll admit, we made the leap to use Epic Apps on blind-faith. We simply found them on the internet. Talk about hitting the ball out-of-the-park, the end-result of our collaboration with them was nothing short of phenomenal. Our good, solid concept quickly became an exceptional one, thanks to their involvement. This is the first-time, in the history of our company, that a 3rd-party's active participation with us created synergy, instead of entropy. They have gone the extra-mile at every step of our collaboration and produced an app that is light-years ahead of our competition. Five stars? What the heck, we're giving them 6!

  • Amazing focus, phenomenal results in a time frame that was delivered well before the deadline we all agreed on. Epic Apps comes with my highest recommendation.

  • I've been working with Epic Apps for well over a year on a pretty large project, and I couldn't be more impressed! The entire team at Epic has been incredibly responsive, even to the point of pushing me to get my part of the work done. As far as the project goes, Epic has completed every aspect of the work on time and with a level of quality that exceeds my expectations. Currently, I'm moving forward on several other projects with Epic and have recommended them to quite a few of my colleagues. The bottom line is that Epic is an outstanding company with great people who know how to design contemporary, cool, sleek, and functional websites and apps. Going with them is a smart choice for your organization.

  • I used Epic Apps to build the 6th Street app and it was an instant success. I was a complete beginner, and Kevin & Scott walked me through the entire process. I had instant success and can say that the App has definitely become bigger than I could have ever imagined. Thank you Kevin & Scott.

  • Epic is working on our second App and we love their work. I highly recommend them. Great product and easy to work with team.

  • Needless to say, you guys rock! Working with Kevin Williams on our app has been a real treat. From start to finish he and his team were consummate professionals, truly listening to and understanding our needs as a client and delivering a product that exceeded our expectations. When the final product was released my entire office was impressed with the amazing quality. All in all, I highly recommend Epic Apps for your next mobile project.

  • As a liquor store that has more than tripled in size over thirty years, we are always looking to stay ahead of the curve and build our base of loyal customers. Scott and the entire team at Epic did a fantastic job in building us mobile platforms that helped augment all of our other marketing efforts. They’ve also been extremely helpful in their tech and marketing support since the app and mobile website went live. I highly recommend to any business that hasn’t gone mobile yet to jump on that train quickly and take advantage of Epic’s expertise.

  • It was a true pleasure working with Kevin and Epic Apps. They have a top-notch product and we have seen amazing results from the mobile app they built us. As a bar owner it is key for us to keep our content, verbiage, events and specials constantly updated and their solution allows us to do just that. We would work with Kevin and Epic Apps again in a heartbeat. Thanks for all of your hard work Kevin and if you are considering using Kevin’s company please do not hesitate to contact me if you have additional questions about what they provided for us. Great Job!

  • Our company is a small non-profit company with an important mission. We really weren’t sure where to start in designing a mobile app. We were referred to Kevin Williams, of Epic Apps, and never looked back! He was very intuitive and was responsive to all of our suggestions and specific needs for the app. He is a super guy, kept us informed during the design phase, communicated well at every turn, and our app looks fantastic. Very user-friendly, simple-yet-informative, and well-priced as well. We are 100% satisfied.

  • Epic Business Apps took our raw idea and worked magic, turning it into a professional, slick-looking product that’s simple, intuitive and user friendly. Founder Kevin Williams walked us through every step of development with patience and wisdom, not only adding value to our product with his guidance, but making the process painless and fun. We highly recommend this company for any business looking to expand its reach into the mobile digital world!

  • Epic Apps made everything easy when starting our first mobile app. From the start they were constructive in helping us decide what to feature and worked with us one-on-one to make sure everything was satisfactory to our requests. They were very professional, helpful, and got back to us in a timely fashion. I would definitely recommend this company for all of your mobile app needs!

Pricing FAQ

What about Enterprise App pricing?

Enterprise apps can be completely custom apps, hybrids or Web apps, depending on what makes sense for your company. We’ll help you make that determination based on the features and functionality you’ll need in your app.

When should we consider Web apps or hybrid apps?

The most obvious difference between custom native apps and Web apps is that native apps are installed directly on your phone or tablet through an app store (i.e. iTunes or Google Play), whereas Web apps are run through a Web browser (i.e. Chrome, Firefox). If you don’t require your app to be on the app store or you don’t need a lot of native functionality (i.e., camera, accelerometer, GPS, etc.) then you might consider a Web app. You’ll sacrifice a little in overall speed and performance, but you’ll save considerably on development costs and the app can be utilized on any device as long as there is a cell signal or WiFi connection.

What is included with custom app development?

Custom development is highly specialized, and specific to the platform you’re creating the app for (i.e., iOS, Android, etc.). Our process involves in-depth discovery meetings to determine your particular needs, business and/or system requirements definition, storyboards & wireframes (blueprints) showing screen layout and interface (UI) design , graphic design, development, quality assurance (QA) and bug testing, user testing (UAT) and final delivery.

When do platform apps make sense?

Many businesses or individuals don’t need a complex app. For example, most restaurants usually want to showcase their menus and events, maybe sync with Open Table or offer ordering and payment through their app. All of this can be accomplished through a platform app. By incorporating customizable templates and select functionality, you can save considerably on development costs while creating a very professional and highly functional mobile app.
