Droplet
Hydration through empathy.
Explore the prototypeA neurodivergent-aware iOS hydration companion that replaces shame, streaks, and friction with calm, low-effort cues.
A water app that doesn't punish you for being human.
From rigid streaks to gentle re-entry
Droplet reimagines hydration tracking for neurodivergent users — students, remote workers, anyone whose days don't fit a 9-to-5 mold. The product replaces multi-step logging, punitive streaks, and generic notifications with one-tap glasses, calm visuals, and a pause-without-guilt model. Built end-to-end across research, design system, wireframes, and a high-fidelity iOS prototype.
See the working prototypeStandard water apps quietly fail neurodivergent users.
Habit-tracking apps assume a stable routine, perfect attention, and a tolerance for friction. ADHD and autistic users meet a wall of multi-step logging, generic interval reminders, and red "missed goal" rings that turn an inconsistent week into a story of personal failure. The pattern is consistent: download, configure, miss two days, abandon.
Research surfaced five sequential breakdown moments — each one preventable with the right design choices.
Habit-app abandonment
Calm surfaces. Honest progress. Zero shame.
A dark, low-stimulation interface that reads as a moment of breath rather than a productivity tool — colored glows for celebration, never for punishment.
Warm glow, not red ring
Progress is communicated through luminance and color temperature, not absence. A goal ring that pulses gently when hit; a soft amber "behind today" state that never says you've failed.
Logging in one tap from anywhere
Widget, Lock Screen, Watch, Dynamic Island — every entry point logs the most-used preset in a single touch. The full app is for review, not for the daily action.
The User.
Two primary personas anchored the work — both neurodivergent, both already burned by water apps, both giving Droplet one more chance. Their journey through standard apps is a five-stage failure pattern that shaped every design decision that followed.
Methodology & scope
Semi-structured interviews with neurodivergent adults who had abandoned at least one habit-tracker, paired with a journey audit of three top-rated water apps. Synthesis through affinity mapping into two composite personas and a five-stage failure journey.
Who Droplet is built for.
Full-time psych student juggling classes, a part-time job, and late-night study or gaming sessions. Self-care drops out the moment hyperfocus kicks in. Past planners and reminder apps have left a "I can't stick to anything" residue, so any tool that adds guilt gets uninstalled fast.
Build a near-automatic hydration habit during study blocks. Stay clear-headed in afternoon classes. Use an app that feels supportive — not one that tracks every "broken streak." Cut down the number of self-care apps by surfacing cues where Alex already looks: lock screen, watch.
Hyperfocus erases hours. Multi-step logging (pick drink → adjust oz → confirm) feels like too much in the moment. Generic interval notifications get muted by week two. Red "you missed your goal" rings trigger shame and outright app abandonment.
Checks the phone constantly between tasks but rarely opens wellness apps unless something is right there on the lock screen. Drinks big bursts when reminded, then forgets for hours. Strong preference for one-tap actions — widget or notification — over navigating screens.
Neurodivergent remote designer whose week shifts with project demands and time zones. Some days are back-to-back calls; others are deep-focus stretches into the night. Has tried — and abandoned — many habit trackers that demanded more executive function than they returned.
Stable energy and focus across long workdays via consistent hydration. A tool that adapts to "modes" — meeting-heavy, travel, low-energy — without manual reconfiguration. Copy and visuals that acknowledge neurodivergent realities. Trend visibility without daily-completion pressure.
Standard apps assume stable hours; reminders fire at irrelevant times. Complex setup, detailed analytics, gamified challenges become another project. Strict streaks reset all prior effort after a few missed days. Decision fatigue around exact ounces and drink types.
Switches between laptop, phone, and watch — prefers widget/complication entry points. Uses calendar blocks and focus modes; tools that align with these fit the day better. Pauses routines during travel or crunch and needs guilt-free re-entry. Reads microcopy closely; sensitive to scolding language.

Re-engagement & Drop-off
Cautiously optimistic
Downloads after seeing it recommended for focus. Hopes it might be different this time.
Mild frustration
Multi-step setup: weight, activity, daily goal, reminder cadence. No schedule modes for different day types.
Reminders get muted
Generic interval pings fire during hyperfocus or meetings. Logging requires open → pick → adjust → confirm.
Streak resets, shame
Two missed days. Streak reset to zero. Red "missed goal" rings. No validating copy, no recovery path.
Deletes the app
One halfhearted log, then revokes notifications after a reminder fires during a client call.
Three principles that shaped Droplet.
One-tap, surface-first logging
The single most-used preset is logged from a widget, Lock Screen, or Watch face — never requiring an app open. Logging during hyperfocus has to be muscle-memory, not a flow.
No streaks. No red rings.
Progress is celebrated when it happens; absence is acknowledged with calm language ("a busy day is okay") and a one-glass re-entry — never with a punitive reset.
Schedule that bends, not breaks
Workday, travel, low-energy, and rest modes change what reminders fire and when — without manual reconfiguration. The app adapts; the user doesn't.
Design System.
A complete, dark-first design language for Droplet — 26 color tokens, an Epilogue type scale, primitive components, and an icon set, all engineered to feel calm at full saturation.

Calm motion. Gentle voice. Soft glow over hard edges.
Every animation curves on cubic-bezier(0.2, 0.8, 0.2, 1) — quick to start, slow to settle. Sheets enter from below in 380ms. Toasts fade rather than snap. The progress ring uses a 700ms stroke-dashoffset transition tied to a colored drop-shadow that swaps from primary blue to success green when the goal is hit.
Microcopy never blames. "A busy day is okay. You can always start again with one glass." replaces "You missed your goal." The result is a system that feels measured and careful at every interaction layer.
Wireframes.
Translating research insights into structural blueprints — from a tightly scoped information architecture to mid-fidelity flows that proved out the one-tap and recovery-nudge patterns before any visual polish was applied.
Three tabs. No deeper than two screens.
A deliberately flat hierarchy — every primary action reachable in one tap from the home tab, every secondary action one tab swap away.
Four screen archetypes.
Pre-fidelity layout passes — proving structure and information density before any styling was applied.
Two flows that proved the model.
The Home screen and Quick Log sheet — annotated mid-fi mockups that locked structural decisions before visual design.
What changed, and why.
Feedback Loop
Three rounds of usability tests with 6 participants surfaced a consistent objection: even gentle "you're behind" framing felt judgmental. Copy and visual treatment for the under-goal state were rewritten to remove any temporal language.
Technical & Structural Changes
- Removed the streak counter entirely from the data model — not just hidden in UI.
- Collapsed onboarding from 5 screens to 1 with sensible defaults; settings absorbs the rest.
- Replaced "missed goal" red ring with a soft amber recovery card that fires a single, shame-free nudge.
- Schedule modes (Workday, Travel, Low-Energy, Rest) became first-class data, not a settings checkbox.
- Quick Log sheet became reachable from the widget, Lock Screen, and Dynamic Island — not just from the app.
Prototype.
A high-fidelity, click-through iOS prototype built directly in the design system — every primitive, every motion curve, every microcopy line ready for stakeholder review and engineering handoff.
Droplet · iOS Prototype
Tap through the full Today / History / Settings flow including the Quick Log sheet, recovery nudge, and goal-hit celebration.
Two flows. Both shame-free.
Quick Log · One-tap from anywhere
The primary action. Logs the most-used preset in a single tap with optimistic UI, a frosted-glass success toast, and an inline Undo on the most recent row.
Recovery Nudge · No streaks, no shame
Triggered when consumption is below 35% after 2 PM. A calm amber card replaces what would be a "missed goal" red state in any other app.
