Web Applications: What they can do for you.

October 11, 2016

Photo of Weston Walker

For years, companies looking for applications to increase employee productivity, customer visibility, or user experience only had the option of building stand alone applications. These applications came with many downsides, including multiple installs, multiple versions for different operating systems, and the inconvenience of having to install them on user's devices.

What changed?

Every year the progress of technology increases and the world wide web is no exception to that. Web technologies have increased to the point where sophisticated enterprise applications can now be built for the web. These web applications provide similar functionality and numerous benefits over a traditional desktop or mobile application.

  1. Inheritently accessible to all users from anywhere because the application lives on the web.
  2. Login systems that provide security and visiblity to only the people you want in your application.
  3. Secure database storage so your application is driven off the data from your company.
  4. Dynamic content loading allows no refreshes of the browser when accessing new content or pages vastly increasing performance and user experience.
  5. The ability to interface your company's data to your clients anywhere in the world.
  6. One application that can be accessed from any size of device or operating system.
  7. No installation required by users.

How does One Hat fit in?

One Hat specializes in web application development. For years, we have provided reliable sophisticated web apps for numerous clients. The process of building a large scale web application can be a tedious endevour but through our experience over the years we have perfected the steps to deliver clients the web applications they deserve.

  3. Based on step 2, scope out the functionality and user interface you need.
  4. Finilize the specifications with the client.
  5. Develop the application.
  6. Thourougly test the application.
  7. Deliver!

We requested One Hat to build us a used equipment website with functions that allowed us to better market and manage our inventory. Not only was the (behind the scenes) programing effective, but as importantly it was well accepted and found to be very user friendly. Years later we continue to use this website with confidence and satisfaction.
Thank you Matt! Just wanted to mention that your staff has been great to work with on this project. I know the bullseye has moved around a bit but Tristan has continued to push through and still take the time to explain the differences between our current dinosaur and our new ferrari.
For over fifteen years, we’ve had the pleasure of working with One Hat for our graphic design and web design needs. They have always done an outstanding job on every assignment and have provided great customer support as well. We hope to be working with Scott and his team for many years to come and highly recommend his company for anyone wanting solid, dependable results.
ICU Mobile is thankful to Scott Spuler and his team for their ability to meet our web needs both in technical approaches and in design concepts, providing us with new user friendly websites which incorporate and make more contemporary, our look and function, reflecting better, the image and information of our ministry. Scott and his team are gifted in their areas of expertise and are professional, diligent and honest in their work with us, and have continued to provide educational and practical support. We are pleased to recommend them to others, confident that they will provide excellent, responsible service.
