AnyList — Case Study

A feature added to a Grocery Lists Sharing App

Another story from my journey at Ironhack!


Analyse an already existing mobile app (android / iOS)and incorporate a new feature into the existing product.

I had two weeks time to complete this task and for the first time on my own, which was both challenging and exciting.

I chose AnyList as I had to go through a drill to choose a grocery listing app for myself as I am a forgetful person and I have to keep track of groceries along with my partner, AnyList made the job easier by sharing the lists with my partner and we both could update our lists in real-time. The platform I would be working for is Android.


I started off by doing some research about AnyList. There’s no shortage of grocery list apps in Apple’s mobile app store, but the real kicker of the AnyList app formula is its ability to share and update multiple shopping lists in near real-time. AnyList was founded by Jeff Hunter & Jason Marr, based in California. They were roommates and they often bungled the buying process.

Founders of AnyList App

The app was first launched in Apple Store, in 2011.

Market Research

To have a better idea of what the competitors are offering and where does AnyList lag, I conducted Feature Competitive Analysis with other companies like Out of Milk, Listonic, Our Groceries.

Feature Competitive Analysis

I noticed that AnyList does not offer Voice Input feature and it does not suggest items to add to the list as some other competitors do.

Playstore Reviews

I looked into the reviews at Playstore to find out what people are liking and disliking about the app.

Good app for what it does but I shouldn’t be required to have an account to make a list. Why you need my information to make a list? — Cameron Williams

In-app experience was great, but the app is missing a widget, which is critical for any list app. — Jan Smrcina

“ Needs to be smart to remove similar items from all lists. ” — Hoda Mustafa

User Interviews

I also interviewed 5 users to dig into the pains of our users and below is what they say!

Want to add voice notes to a list. — Fatima

More options for sharing as text. — Irene

Want to put a reminder to a list. — Harry

“Add pictures with an item. — Ashar

Doesn’t take permission for list sharing. - Haris

Affinity Diagram

I put all the insights from User Interviews and Playstore Reviews into Affinity Diagram to brainstorm about the solution.

Then I created a Proto Persona of my primary user while listing his goals and frustrations to have a better idea of our user.

Primary Persona

Lean UX Canvas

To have a better idea of the whole scenario, I put my ideas onto the Lean UX Canvas. Now I had a clear idea of what my business problem is, who is my user, what solutions I can provide to help the business and user.

Lean UX Canvas

User Flow

I defined the user flow that Harry follows to Set Reminder to Albert Heijn List in his app.

User Flow — Reminder Set


Then I focused on the main problem and defined the problem statement and concluded a Hypothesis for the problem.

Problem Statement

Harry needs to find a way to remember purchasing the grocery items at the right time so he can have them in stock when needed.

Hypothesis Statement

I believe that by having a feature for setting reminders in his grocery listing app, Harry will be able to timely stock the required grocery items.


Concept Sketches

I created two versions of the feature. In Version, A user could set only one alarm with one list. Whereas in Version B user could add more alarms to a list.

Version A and Version B (L-R)

Concept Testing

I conducted Concept Testing by sharing my sketches with users and recorded their feedback.

  • Version A preferred; single alarm for one list
  • Date and Time Picker Display Change

Lo-Fi Prototype

I incorporated the feedback from concept testing into Lo-Fi Prototype. Changed the display of the Date and Time picker and made the feature for one alarm with one list.

Lo-Fi Prototype

Atomic Design Inventory

Then I started digitizing my prototype. First created an atomic design inventory, where I had my color palette, fonts, buttons, app top and bottom bars, and also the screenshots of existing pages and layouts. I used them to design the new layout.

Atoms & Molecules of Inventory

Hi-Fi Prototype

Below are the images of my Hi-Fi Prototype.

Home, List, Reminder Pages (L-R)
Reminder Set List, Reminder Set Home, Reminder Ring Pages (L-R)

Also here is the link to my Figma Prototype;

Usability Testing

I conducted the Usability Testing on my Hi-Fi Prototype and noted down the feedback

  • Add Reminder Message
  • Reminder date mentioned on the list when you CHECK reminder


In the next steps, I would incorporate feedback from Usability Testing and also add other features listed on the Lean UX Canvas to my prototype and then test and iterate.

Key Learning

It was a happening journey in which I learned a lot. I learned using Figma Components, creating Atomic Design Inventory, and following Design Guidelines(Material Design) of the platform, you design for. One big-time lesson is to keep track of time, but not to rush!

Catch you in the next challenge :)

I am a Multimedia Designer, with a creative and analytical mind. Human psychology also interests me. I am learning to create User Centric Designs these days.
