Android and iOS mobile application built to facilitate residential oil delivery services on behalf of Heatable.

Technologies Used

  • Xamarin.Android
  • Xamarin.iOS
  • Custom built API's

"Heatable makes ordering heating oil as easy as tapping and swiping. Simply check your super low price and delivery date, decide how many gallons you want, swipe to order and you’re done. Heatable puts low-price heating oil at your fingertips. "

This application was designed and engineered from the ground up at AndPlus. Our goal was to create a one-stop-shop for anyone buying oil. No more calling around to find the lowest price, no contracts, no fishing for coupons and no wondering when your delivery will take place. We did just that.

The Approach

The Heatable project was a true collaborative effort. Our in-house (as always) team worked in tandem with Heatable's teams in Ireland and Maine to design and engineer a cross-platform application.

We were tasked with designing an intuitive user interface that allows users to complete their orders seamlessly and with no instruction necessary. The requirements for the application were for the user to check that day's oil price, select an exact delivery amount in gallons, confirm delivery date/location, view order history and manage an account.

This application is the first of its kind and brought an age old industry into the modern era.

The Transformation:

The process of ordering heating oil has long been a chore. No, really, lots of people actually have to order their own heating oil. We were surprised too. Calling in the middle of your work day and having to set aside a long window of time for "estimated delivery" needed to become a thing of the past. AndPlus and Heatable were determined to transform this process into a quick tap and swipe interface that gets you in and out of the app in no time.

After reviewing the requirements, the AndPlus Technical Architecture team decided that Xamarin was the best way to get this app built for both Android and iOS. Sharing a codebase means that features are built at the same time, the logic is identical across apps and updates are pushed to the app stores in tandem. 

Our design team knew that this needed to be a quick process. Nobody wants to be in an oil-ordering app for long. The idea was to streamline the process so that you can easily hop in, get what you need and not think about it again until delivery day. It was designed with a beautiful orange theme that fits their branding, big bold text and the now signature "Bring the Heat" button to confirm your order.



AndPlus understands the communication between building level devices and mobile devices and this experience allowed them to concentrate more on the UI functions of the project. They have built a custom BACnet MS/TP communication stack for our products and are looking at branching to other communication protocols to meet our market needs. AndPlus continues to drive our product management to excellence, often suggesting more meaningful approaches to complete a task, and offering feedback on UI and Human Interface based on their knowledge from past projects.
