TAP app

A cross-platform application for food and drink orders





Business size:

Small Business


Building an application for online ordering in various restaurants, ready-made solutions, and features created by the company's developers were used. Thanks to the experience and expertise of the team, the finished product quickly passed all the tests on the app markets and was successfully launched.

During the work on the project, several key options were solved:
  • Developed a stable and highly popular cross-platform app
  • Adopted the platform for different restaurant ordering
  • Implemented the most common payment systems.



  • Lack of time for testing and launching the application
  • Tight schedule
  • Lack of website


  • High demand for such applications
  • Works with many restaurants, not with only one
  • Quick decision making on various issues


Class Technology Solutions Ltd (CTS), a UK leading Education ICT solutions provider with over ten years worth of experience, turned to Computools with an idea of creating a reliable and convenient app for quick restaurant ordering. The main goal was to provide users with a cross-platform application for food and drink orders. However, the CTS' customers are restaurants and cafes, that were added to the ordering platform. After negotiations and intro meeting high-level goals and expectations were identified. Int allows the Computools's engineers more clearly understand the needs and requirements of the client.

The finished app aggregates menus, tables availability, open-close hours and other info of many restaurants (the amount is constantly increasing). A user can make orders both off-site and on-site, as well as track the status of the order, do payments including tips, add order notes etc. The convenience and popularity of the application among users makes it attractive for restaurants and cafes that seek to use all channels to attract visitors and customers.

Digital Platform & Technology

The stack of necessary technologies is determined by future application functions, necessary capabilities, and tasks. To select the best technologies, programming languages​​, and frameworks, Computools's engineers study ready-made solutions to similar problems and existing technologies.

Communication Framework

One of the important points of work on the project is the creation of a stable and high-speed communication system. This allows you to make decisions quickly and get approval.

At the initial stage Slack was used for interaction. This made it possible to exchange information, conduct video and audio conferences during the discussion of the project.


Preliminary writing of the specification allows creating an algorithm of mandatory actions and tasks of the project. And also to avoid errors in development. The list of actions is formed in parallel with the interactive prototype and is finalized after the completion of the project.

Goal - order food and drinks.

The company always carefully selects team members to work on each specific project. Computools choose specialists, whose experience and skills are best suited to accomplish the task. A strict selection of employees was carried out for this project, taking into account their qualifications and level of expertise. The team included development engineers and managers.


Maintaining the productivity of the entire team is the core of the successful interaction of all its members. Besides, it stimulates the development of each involved employee and contributes to his professional growth. To do this, we use a variety of methods and tools.

Feedback sessions

An important component of work on a project is getting feedback. This applies not only to interaction with the customer but also between team members. So everyone gets the opportunity to learn about their strengths and weaknesses and become even better as a professional.


Brainstorming is recognized as one of the most effective ways to find innovative solutions. At such meetings, developers can offer any idea, even the most incredible. In the discussion of ideas, original solutions are created.

Dev Meeting

Developer's meetings help the team interact better and share experience and acquired knowledge. Moreover, this allows identifying errors or bugs in the code that are easily fixed at the development stage.

Internal Communication Flow

The internal communication system on the project consisted of two parts. Skype was used to quickly discuss and resolve urgent issues, and tasks were distributed through Jira. Such an ecosystem helps to track the status of tasks and quickly find solutions to difficulties.

Project Management Methodology

Scrum was chosen as one of the most effective application development methodologies to date. The numerous advantages of this methodology make it effective and convenient. In addition, the use of scrum increases the productivity of the whole team, allows to easily and quickly identify errors in the work, slipping on time and to eliminate them.
Dividing the development process into stages with short periods and daily reports makes the task execution easy and quick. Scrum also managed to prove its efficiency and productivity for performing urgent tasks with short sprints and tight deadlines. It allows not only to accelerate all processes, but also to save the customer’s funds.

Design development was carried out according to the established plan and schedule. Basic UX/UI development was done at the prototyping stage. In the future, during the development, the necessary functions and application options were added.

On Client’s Side



The application was launched according to the agreed plan and the established schedule. Before launch, automatic and manual tests were performed to verify the stability and performance of the application.



The development was divided into stages, so the transfer was carried out in parts. Due to this, recent changes have already been made to the finished version. After completing troubleshooting of the application, we launched another series of final tests to make sure that everything works correctly.



The convenient and intuitive interface of the finished app eliminated the need for education or development of training documentation or videos. However, company’s developers are always ready to help clients and maintain the apps.
