Evaluation Objective
Evaluate the AqarCircle android app experience in order to pinpoint existing usability issues; then provide a report that lists all found issues sorted by severity and propose solutions to those issues based on UX expertise.
Project methodology
The project included two phases;
1. UX evaluation: Heuristic evaluation & Competitive Benchmarking;
2. Problem Ranking & Recommendations.

Let's start with Heuristic Evaluation:

Studying the product in depth and understanding the business, a set of personas is created to represent the target market and analyze current user behavior.
Needs  & Features
Based on this individual description of each persona, I came up with a  list of needs that are translated into features  that should exist & function well in the app.
Going through the app’s analytics, I was able to understand current user behavior; what users came to do, how often they could successfully finish their journey, where they quit, why…..
User Journeys & Usability Heuristics
I evaluated the app performance according to Nielsen Norman’s 10 Usability Heuristics as well as a list of user journeys; which are the tasks users are expected to perform while using AqarCircle.

Competitive Benchmarking
Each item had several sub-items to evaluate AqarCircle against. In the end, I incorporated the impact of each item in the final evaluation to be able to sort the found issues according to the most critical to app performance.

Evaluation Results

Based on the heuristic evaluation & the benchmarking analysis, I compiled a list of issues, rated most critical to simple observation & proposed solutions to those issues. Some fixes were related to screen UI design; like the ones in the above image and the case study's cover image.
