JENKINS
What Is JENKINS?
Jenkins is a reminder app built to reduce the stress of forgetting to reply. It keeps track of conversations, summarizes what was missed with AI, and prompts users to reconnect with the people who matter.
Project Limitations
This project was part of my Master's HCI Design for Startups course, requiring strict use of the Lean Startup methodology by Eric Ries.
Why A Smart Reminder App?
For a long time, I hurt my relationship with friends, colleagues, and family because I struggled to stay on top of emails, messages, and calls from them.
Through research, I discovered this challenge is common for many people.

The TLDR
A busy professional juggling emails, messages, and calls needs a way to stay on top of important conversations because they often forget to reply and risk straining relationships.
The Problem
Problem Statement
A busy professional juggling emails, messages, and calls needs a way to stay on top of important conversations because they often forget to reply and risk straining relationships.
Importance of the Problem
"It takes 23 min to focus after getting distracted." - UCl.edu
"Workers who completed tasks in parallel took 30% longer and made 2x as many errors." - Richard L. Byyny, MD
"48% have had a relationship negatively impacted because of their slow response to messages." - Secure Data Recovery

The Solution
Smart Reminders
Smart reminders would filter out the necessary notifications from the sea of many notifications that busy people receive.

The Research
Literature Review
Reading Takeaways
The brain focuses inward and puts more mental effort into trying to remember many future tasks while working on something irrelevant without noticing its surrounding. The opposite is true when it has to remember a few things.
Little stress can help with PM, but chronic stress drastically decreases the PM performance. Busy students with high state anxiety, should very low levels of PM performance.
Recommendations were to create an environment that would promote the use of recognition rather than recall.
Multitasking is dividing focus into separate tasks, and slows down progress.

Persona - Student
Samantha Miller
Samantha is a part-time barista and full-time law student at NYU in New York City, New York.
"I constantly juggle iMessage, Gmail, and WhatsApp, and often receive messages while I’m studying. I tell myself, “I’ll look at it later,” but then forget to follow up. As a result, I’ve missed both small and significant opportunities—including job prospects—simply because I didn’t respond in time.
I need an app that lifts the mental load of remembering to return back to messages I mark as important. This would reduce the stress and guilt I feel when I forget to reply to someone important—whether it’s a classmate, family member, friend or future job prospects."
Goals
- Stay on top of communication with team members, family, and group projects.
- Avoid missing important follow-ups
- Reduce mental clutter
- Find full time associate position.
Behaviors
- Uses many messaging apps (email, SMS, Whatsapp)
- Sees notification but forgets to return back to them.
Pain Points
- Mental fatigue from juggling too many messages.
- Missed opportunities from potential employers.
- Tools she uses don't effectively prioritize or remind her to follow up.

Market Research
Existing solutions are limited—email plug-ins exist, messaging apps require manual work, calls have no support, and OS automations are effort-heavy.
Email: Tools like FollowUp, Boomerang, and Mailbutler remind you of unanswered emails.
Messaging: Most apps need Apple Reminders; only Telegram offers reminders, but manually.
Phone Calls: No solutions exist.
OS-Specific: iOS Shortcuts/Android Routines allow manual automations.

Brainstorm Potential Features
The mindmaps were made to brainstorm potential features.

Hypothesis Prioritization Canvas (Lean UX)

Hypothesis Testing
Based on the "Hypothesis Prioritization Canvas" above, I created small experiments to undersand the feasibility of the features.
*iOS allows only semi-automation due to privacy rules, while Android supports full automation with flexible APIs.

Visual Inspiration Board
My Jenkins UI design is inspired by images highlighting organization through shapes, lines, colors, and typography.
The keywords that inspirated my inspiration board: High Contrast, Accessible, Bento Box, Organized

Key Pages

Content Funnel Approach
Content follows a funnel approach: general on the homepage, more detail on the messages page, and specific app-based messages last.
Homepage: General overview
Messages Page: More detail
App Messages: Specific conversations
Participant Feedback
3/3 participants loved the funnel approach from general to detailed calling it 'natural,'
UI Consistency Across Apps
Colors match app icons for consistency. AI notifications are presented neatly with a 'Bento Box' layout.

Custom Settings
Automatic and Tailored
Users can customize notification frequency or choose immediate reminders, addressing issues of bad timing or forgotten messages.
Based on feedback, reminders now track frequency after the initial message per hour, not total per hour.
Lo-Fi Feedback
“My meetings tend to be long, I wouldn’t want to be bothered multiple times per hour on non-work related things.”
3/3 felt summaries were useful but wanted them slightly longer.

I tested my design with participants who matched my personas—busy individuals who often overlook notifications do to other responsibilities.
All participants names have been replaced with a random letter.

Usability Test
Usability Test
All usability tests were conducted on Zoom with consent to use cameras, record screens, and sessions for later observation.
Scenario 1: “You just finished a day with back-to-back [meetings, classes, discussions] and want to quickly get caught up on any important messages and message them back.”
Scenario 2: “After a long day, you JUST remembered the notification from an [Apple recruiter, colleague, team member for class]. Find it.”
Scenario 3: “You want to set your close friend Omar as an important sender for Whatsapp in Jenkins. How would you do that?”
Post Usability Test Questions

What do you think this design needs to make it even better?
"A way to know when a message has arrived. A way to order messages because it seems like it's missing."
"A sort of widget would be nice."
"Overall it's really good, but I had trouble adding someone as important. Maybe a way to make that faster."
"What do you tend to do to remind yourself to return back to people?"
"I don't have a method, I just remember it. All of my devices are connected, when I receive a notification and it's important, I drop everything and deal with it."
"I tend to see messages on my lockscreen at the wrong times, so 1 immediately take a screenshot of it."
"I write it in the small notebook that I carry with me."
Results + Updates
Although all tasks were completed, participants faced issues. I prioritized message delivery and “important sender” problems due to time limits.
✖ 2/3 wondered about the order of messages
✖ 2/3 seemed bothered in going to the chat source.
✖ 2/3 asked "When did this message come?"
✖ 2/3 took longer than expected to add an "important sender"
Message Recency
Recent messages appear at the top with timestamps.
Message Time
Each contact shows the last message time.
Quick Add Contact
A bottom-right button lets users mark contacts as important.
Recieved Feedback
Overall Score: 12/15

Looking Back
What I Did Well
Found a specific problem that exists and created distinctive, unmatched solution with no counterparts in the market.
Followed the Lean UX methodology framework.
What I Can Do Later
Explore and test Jenkins widget use cases; let users mark senders as important at the source (e.g., a Gmail plugin for specific addresses, an incoming call, a new message)
Create a functional version of the design thoroughly understand the feasibility.
What I Would Do Differently
Interview more than 3 people to get more diverse responses.
