What is Costless
Costless is an Android app that compares prices on goods and products across popular Kiev grocery stores, thereby allowing users to make better decisions on where to shop and how to get to the selected store.
About the Project
Sergey Shcherbanenko, co-founder and technical director of Sannacode, came up with an idea of Costless at the time he left grocery store he had never visited before. He found that he spent more money than usual. It turned out that prices of the same goods can differ widely in different grocery stores even if the latter are close to one another. One has to check prices for goods and compare them manually in order not to overpay, which is quite inconvenient and time-consuming.
Ultimately, Sergey aimed at creating an application that would help automate this process and make lives of millions of consumers easier.
Sergey decided to make an application that allows one to track spending on day-to-day purchases and thereby save time and money, the greatest resources in the life of a modern man. A small number of available services aimed at monitoring and comparing prices, as well as their limited functionality, strengthened Sergey's desire to create a unique product even more.
The Sannacode team faced the challenge of creating an application that would include the following functions:
- Viewing and comparing prices with an instant result displayed on the map just after a user selected the product;
- Automatic recalculation of the total price of the shopping list items in case of price changes, if any;
- Tracking of special offers in super- and hypermarkets;
- Showing geographical position of super- and hypermarkets on the map.
In developing Costless, we relied on previous experience we’ve had after cooperation with large companies and start-ups. The project team consisted of 12 people, namely Web and Mobile App Developers, Business Analyst, UI/UX Designer, QA Engineers, Content Managers, Copywriter and Project Manager.
We designed the product prototype and created the application architecture. It took three weeks for us to make the UI and UX design. We used Sketch, Marvel, and Adobe After Effects to develop the latter. After we reached consensus on the visual design of the application, we moved on to developing a back-end where we utilized PHP7, Laravel5, Redis, and MySQL.
The Android app entailed working with Android Studio, Android SDK, Retrofit 2, RxJava, Google Maps, Facebook SDK, Google+ SDK, Crashlytics. The development of the Android app main functions took three months while the development of the back-end took four months.
The most time- and labor-consuming part of the project was filling the database with each item manually. We continue develop new functions available on the Android app, we update and maintain the project database, and we develop the iOS app version of Costless.
The project’s monetization relies on advertising.
Outcomes and Future Plans
At the moment, Costless is at the beta test stage and is only useful for Kiev grocery stores. In the near future, the Sannacode team intends to increase the availability of super- and hypermarkets located in the cities of Ukraine and other countries. We will also increase the number of chain stores in the app, add a function of receipt scanning and notifications on available discounts.
