THE STORY

Using our phones before sleeping is bad. We know that, but still do it.

Existing solutions don’t meet people where they are. Our project started with the acknowledgement that our phones are stuck to us and people resist change.

THE Solution

What if we let people use their phones the way they want while encouraging sleep intrinsically?

Digital Melatonin is a bedtime app that helps reduce phone usage before sleep. Users select their desired sleep time and choose an intensity level (1, 5, or 10) that determines how strongly the app's features affect phone activity.

Here’s the deck. Watch the pitch here!

The metaphors

Digital Melatonin is a digital "pill" that activates features to reduce phone use before bedtime.

Digigram (dg) is our playful unit of measurement, like digital milligrams.


Dosage describes the intensity level (1, 5, or 10 dg) that determines which features are activated.

Dosages and features

While each intensity level (1, 5, and 10 dg) comes with preset features, users can customize their experience by editing, disabling, or regrouping features for each dosage.

Product showcase

Onboarding

During onboarding, users are introduced to the concept of Digital Melatonin, and take a quiz or self-prescribe their typical dosage.

Taking Digital Melatonin

After receiving a notification, users can decide if they want to take digital melatonin tonight. If they do, they’ll set a goal and choose a dosage.

Home

On the home screen, they can see a graph of features being activated over the time from the pill intake to sleep goal and options to edit and cancel features.

1 Digigram Features

Short form video tracker

Bedtime routine helper

Gradual dimming

Gradual B&W mode

Timed muted notifs

The short form video tracker is a lightweight feature that overlays social media apps to help users keep track of their short form video intake.

5 Digigram Features

Sleep exercises

Calming content

Reverse snoozing

Sleep exercises interjects bedtime phone usage with increasingly frequent 20-30 second exercises that help relax the body and mind for sleep.

10 Digigram Features

Intentional usage

Exhausted phone mode

Slow battery charging

Intentional usage requires users to set a goal and time limit each time they use an app, making each phone interaction purposeful and time-boxed.

Bedtime Statistics

The statistic tabs provides a weeks overview, with toggles to overlay screen time, sleep, and digital melatonin usage.

THE OUTCOMES

Moonshot 1st Place

On Demo Day, I pitched on behalf of my team, and our project received a unanimous vote from all 4 judges.

“Typically teams hit 1-2 out of 3 targets, but Digital Melatonin hit 3 out of 3 (idea, design, pitch) out of the park.”

Missy Yarbrough, Moonshot Judge

“Seriously. Great work today! Proud of you and how it turned out. You did amazing.”

Rocky Montez-Carr, Moonshot Mentor

“This incredible team delivered a project that redefined creativity, innovation, and impact.”

Luke Preston, Moonshot Organizer

Process Overview

Timeline & Roles

Problem definition

What’s a meaningful project?

I led 2 ideation sessions with the team. We started with 30+ problem spaces and hypothetical ideas and narrowed it to 11 by voting.

I suggested we plot the 11 ideas on 2 decision matrices and vote for the final problem space based on our interests and abilities.

Secondary Research

Zeroing in on modern-day insomnia

Poor sleep is common and unbiased—it appears across demographics, therefore solutions are impactful and have high social value.

1 in 3 adults in the US don't get enough sleep every day 

70M Americans have chronic sleep disorders

46% of people with sleep problems use Panadol and Melatonin

Unsurprisingly, bedtime phone use is one of the culprits. We each struggled with this, and we could easily interview this group at Berkeley.

1 in 3 young adults reported smartphone addiction

93% of Gen Z admit they stay up past bedtime due to their phone

42% of people have poor sleep quality with bedtime phone usage

Competitve Analysis

Existing solutions: What isn’t working?

Productivity apps tell us to exclude our phones,

…but it’s not sustainable or realistic for many

“I hate losing control of my phone. It’s so jarring

“If an app blocks me from using something for more than 30 seconds I would delete it

“I felt violated when Regain kicked me off of Instagram suddenly”

“I had to keep turning off my Apple bedtime settings”

“I downloaded challengers just to delete it within a week”

Sleep apps focus on providing activities to add to people’s routines,

…but people already have their own phone routines

“Going on social media at night is a reward for my day”

“Mindless scrolling is my transition between work and sleep”

“Tiktok helps me dissociate

“I go on Youtube shorts to turn off my brain. A meditative exercise would detract from my sleep or unwind time.”

“I’ve conditioned myself to fall asleep listening to the same Youtuber for the past 5 years”

User interviews

Meet Sarah and Mark, our personas

We collectively conducted 20+ student interviews, 5+ mentor interviews, and 1 professor interview to understand people’s bedtime routines, motivations, and pain points.

90%

of interviewees identify with Sarah

Sarah

20, Student

Sarah doesn’t plan to change her phone habits drastically and doesn’t like interventions

10%

Mark

28, Adult

Mark actively wants to sleep earlier, reduce phone usage, and appreciates app intervention

I synthesized our research insights into personas, and averaged their bedtime routines and pain points. This allowed persona-driven design, where we could ideate features and flows for different user groups.

Design Deep Dive

Sarah’s pain points

Sarah isn’t particularly motivated to change her phone usage, but she does find time-wasting moments in her bedtime routine. Here's an overview of her routine:

Sarah’s onboarding

Interested in the non-constraining features, Sarah downloads Digital Melatonin. This is her narrated onboarding experience.

Features for Sarah

Sarah starts with the 1 dg pills (feature presets shown). Narrated below are features “Short form video tracker” and “Bedtime routine helper” in action.

Her pain points have been addressed by digital melatonin. She enjoys the satisfying experience and minimal intrusiveness, so she takes digital melatonin everyday, unknowingly cutting down her bedtime phone usage by 10-20%

Features for Mark and more

For those more motivated to sleep earlier, the 5 dg and 10 dg pills have features with more intervention. Shown below are the “Sleep exercises” and “Intentional usage” features.

Statistics for everyone

In order to form motivation, people need to feel that their current situation needs to change. We do this not by guilt tripping, but providing insights on users’ habits.

Features that didn’t make it

It’s just as important to discuss features that we chose to leave out. Here are 3 of many, and why.

Gamification

Users receive points or rewards for hitting certain sleep goals

  • Positive and negative connotations may hinder intrinsic motivation

  • Game factors can become stressful and actually demotivating

  • Introduces the idea that users can “fail” at sleep

Phone mascot

A character represents the phone’s “sleepiness” over time, encouraging users to sleep since their phone is “tired”

  • Interviewee feedback mentioned that mascots never motivated them

  • Unnecessary and maybe a little corny

  • Lots of effort for minimal positive effect (Bad ROI)

Morning Check-in

Users record quality and length of sleep, and add tags to find correlations between routines and sleep

  • Users may find this burdening or annoying

  • Not essential for helping people sleep earlier

  • We want the app to be lightweight and easily adoptable

Design considerations

Our North Star

Melatonin heavily inspired our features because its characteristics (unintrusive, gradual, and taken case-by-case) addressed pain points with existing solutions. Here are our UI and UX goals.

UI that is calm and clean

  • Lots of white space to prevent excessive cognitive load

  • Minimal intrusiveness for features that overlay on other apps

  • Only informative or functional UI

  • Purple as a relaxing, and low-light-friendly color

UX that enhances existing routines

  • Flexibility for nightly sleep needs

  • Simple and straightforward user flows for daily use

  • Taking melatonin is satisfying and easy

  • Gentle and neutral copywriting that serves to inform

Exploring good UX

I also analyzed popular and award-winning apps to develop my design intuition for Digital Melatonin.

Accessibility

Font size and colors were chosen thoughtfully to pass A11y guidelines, verified by the A11y Figma plugin.
