At the end of my UX\UI design studies, I was asked to design a product in the form of a mobile app. I did not want to redesign an existing product, so I decided to create something new from scratch.

One night I was sitting with my friends at a bar in Tel Aviv, and when we got to pay the bill, I realized that this simple task comes with many issues, in a world where everything is done over the smartphone, the payment method seemed outdated to me. That was the point I realized that I found a ’pain point’ that has no solution. This is where Kalyoo was created.

The Concept

From the beginning I knew the app would be on dark mode. Since it is targeted at people who go out to bars at night, dark mode would be gentle and right for the human eyes.

From the research, I found out that the leading age group that goes out to bars is between ages 20-30, With that in mind, I wanted a lively, younger, and refreshing color, so I chose the color purple\pink and I have added small illustrations of alcoholic beverages in the background that gently integrate and fits for the atmosphere of nightlife.

App Goal

Creating a better atmosphere at the bar that isn't dependent on the service, making the bill payment process faster and easier and getting rid of menus & receipts.

The Problem

Total dependence on the waiter for any action the user wants to do (ordering food, checking order status, asking for the bill and payment).

Calculation and division of each individual must be done manually.

Waiter is needed for payment, which usually takes time.

The Solution

Option to order via a menu from the app at any given time without the need for a waiter and an order status page.

Personal bill calculates how much each person should pay according to what he/she ordered (sharing or individually) Payment via app.


I conducted a market research using a questionnaire in order to understand consumers' habits, how often they go out to bars, their pain points, payment methods etc'.

The questionnaire consisted of 22 questions and had 94 respondents that represented several different target audience and customer types.

Besides the questionnaire, I also did competitor research and understood what assumptions they made and this helped me plan and design the application in a better and more accurate way.
