Let’s Shop! – Design Proposal


by Group 4: Sara, Bo & Qi

We intend to create a service that will make food shopping a more pleasant and easier experience for the customers. Going food shopping is something that we all have to do and it can be a boring and lonely task. We aim to change this by adding a fun and social factor to it with our app. The target audience are shoppers who find themselves sometimes lost and alone in the aisle at the supermarket, trying to remember what they needed to buy or why they even went to the store. What makes our app unique is its shopping together function, which will make shopping a new way of socializing with friends. Our hope is that the absence of this particular kind of app in the market and the need for it will make people gravitate towards it when word spreads by the social functions between the app and other social media.

The main functions of the app

Considering that the implementation of the app will be limited by our programming skills, we decide to make a MoSCoW analysis of the main functions.

Must Have

Bild 20Shopping List

The Shopping List is the most essential part of our app and Shop Together is our highlight function, so we decided it is a must to implement. In this function, user can create their shopping lists and share them with friends to inspire them or to allow them to go shopping together. They can also use the double check function to make sure they didn’t forget an item on their shopping list. Its structure is shown as left[1] :

News Feed  and registration                                                          

The function of the News Feed is to show the activity stream of you and your friends within the app [2].For example: User A just created a shopping list; User B is now friend with User C; etc. Users can also leave comments, such as could anyone buy me a milk?   The registration function will use sign-up and sign-in design patterns and also allow users to invite friends to use the app.[3]Bild 21


Should have                                                                               

Some more functions should be included to make the app more functional and helpful for users.

Could have                                                                                 

What we could have is the Store function, which is closely related with our business model. The purpose of the store function is to help the user locate the nearest store on a map and to give them other suggestions within the same area. The stores can also be rated and recommended by the users where the most popular store or post will be shown at the top[7].


Business Model                                                                                                                                                                     

The business idea behind this is to adopt the “freemium” model, i.e., we will provide a free downloaded app to attract users at the beginning, and when the app gains popularity we can provide a paid premium version with more advanced features such as ads-free. The money will also come from partnership with stores which can put targeted advertisement on our app. We can use an algorithm to identify the individual user’s shopping habits and preferences in order  to suggest the most interesting deals for that individual user. When the app develops mature with the store function, we can cooperate with stores to provide special deals or discounts for our users.

We think that the app will be sustainable because of the users’ access to help develope the different functions, thus also deciding the content of the app after their own needs. The combination of the social aspect, the money saving deals and how the app makes shopping easier will make users’ want to continue using our app.

The inspiration for the different design patterns and it’s functions were found in:
