Slack iPhone Redesign Concept

Current Slack UX pain points and how I propose to fix them.

📋 Description of the project

Like most people in the tech industry, I have used Slack in my work on many occasions. But while I always thought that the UX was intuitive on desktop, I felt the iPhone version could be improved. I decided to analyze in detail what could be revised and to propose a redesign concept.

👨🏻‍💻 Process and work

Low-fidelity mockups

Once I understood the issues I wanted to fix on the Slack UX, I started to do low-fidelity mockups.

Some of my early drawings

High-fidelity mockups with Sketch 49

Once the low-fidelity mockups were finished, I started working with Sketch. But before I even started sketching the redesign concept, I wanted to reproduce the current Slack iPhone UI. It allowed me to better understand the design of their iOS application and ensure that my proposal would respect Slack’s design.

I did the original UI for both the “Aubergine” theme and the “Hoth” theme

Once the original UI was reproduced in Sketch, I started my redesign concept. I made sure to use the prototyping feature of Sketch 49 as you can see below. You can also download the file and try it for yourself. I also uploaded the prototype on Sketch Cloud if you want to preview it directly from your browser.

Versioning with GitHub + Git LFS

I used GitHub (with Git LFS) in order to manage the different iterations of the project.

GitHub allows me to easily see the changes for each commit I made
