This report presents a comprehensive analysis of the heuristic evaluation conducted on the Sri Mandir app. The evaluation was carried out using the heuristic method developed by Jakob Nielsen, which involves comparing an application’s interface against a set of established usability principles while performing typical user tasks. I evaluated the SriMandir app from a user’s perspective, concentrating on its key functionalities and primary flows, including booking a pooja, ordering prasad, offering a chadhava, and contacting an astrologer. The evaluation was conducted using ten usability heuristics provided by Jacob Nielson with the goal of identifying interface issues and providing actionable recommendations to improve the overall user experience.
The usability issues identified in the SriMandir app were ranked on a severity scale from 1 to 4, 1 being least severe to 4 being most severe to help prioritize which problems should be addressed first. Issues with higher severity scores indicate serious obstacles that significantly affect the user experience and require immediate attention, while lower-severity issues, though less critical, were also documented to guide future improvements.

|---|---|---|---|
| Icons Misaligned with Content Meaning | Pooja detail screen | #4 consistency and standards, #2 match between system and real world | S-1 |
| Add Buttons Cause Confusion When Selecting Offerings | Review pooja booking screen in “participate in pooja flow” | #1- Visibility of status, #4 consistency and standards | S-2 |
| inconsistent phone number input excludes global users | fill puja form on participate in a pooja flow | #4 consistency and standards, #7 flexibility and efficiency of use, | S-4 |

SriMandir is a devotional platform that bridges the gap between spiritual practices and devotees, making it easier for people to stay connected with their faith in a digital way. The app allows users to book poojas, offer chadhava, order prasad, consult astrologers, and explore devotional content like bhajans, aartis, and scriptures. Devotees can also set up their own virtual temple to perform rituals such as lighting diyas or offering flowers, and they can earn Punya Mudras*,* a spiritual reward system for their devotional activities. By bringing these features together, SriMandir aims creates a simple and accessible way to experience temple traditions and rituals from anywhere.
The evaluation of SriMandir app was conducted using Jacob Nielson 10 usability heuristics, a widely accepted framework for identifying usability problems in digital products. the heuristics used are as follows
