AllerTrack

Empowering Allergy Sufferers with Pollen Intelligence

Case snapshot

Problem
Existing weather and allergy apps lacked detailed, hyperlocal pollen data, making it difficult for users to identify their specific allergy triggers.
Solution
Designed AllerTrack, an all-in-one allergy companion combining hyperlocal pollen, weather, and air-quality insights to help users understand their triggers and plan their day with confidence.
Role
As Product Designer, I owned the UX strategy, information architecture, user flows, and visual design from concept to launch.
Outcome
1K+ downloads on Android, with hyperlocal pollen forecasts, personalized alerts, symptom tracking, and allergy-focused insights. Innovation with constraints.

Project overview

AllerTrack is a mobile app that tracks climate-triggered allergies like pollen and poor air quality. Users log symptoms for personalized analysis, access 5-day forecasts, navigate cleaner routes, set medication reminders, and identify specific pollen allergens. By blending science-backed data with intuitive design, the app turns complex environmental insights into actionable daily habits.

for 1st launch. Ongoing project with additional feature releases.

What are we trying to solve

Allergies strike seasonally with invisible culprits like pollen, which varies dramatically even within 5km. Users battle sneezing, itchy eyes, and fatigue without context or tools to plan ahead. Existing apps bury pollen data in dense numbers, lacking personalization or habit-forming engagement.

What the product wanted to achieve

01
Track real-time pollen and 5-day forecasts in digestible formats.
02
Build habit loops via symptom logging and reports pinpointing allergy causes.
03
Enable proactive planning: daily predictions, travel routes, and medication reminders.

The speedbreakers on our path

01
Crunched timeline demanded rapid iteration and launch in pollen season.
02
Developers favored reusable library components; I prioritized "non-negotiable" design innovations (e.g., interactive visualizations) while deprioritizing generic features.
03
To manage the overload of information (Successfully overcame by evolving IA accordingly)

Research & key insights

Analyzed top global weather apps from a user perspective - what works (simple forecasts) and what fails (context-free data). Conducted user interviews with allergy sufferers to uncover pain points.

Pollen data lacks context

Pair numbers with plain-language health impacts (e.g., "Low: Safe for outdoors")

Seasonal allergies need education without overload

Drip-feed science via data visualisation

Boring apps fail retention

Gamify logging with animations and visualizations.

Habit formation thrives on simplicity

Streamline symptom entry and reminders for daily consistency.

A dead-simple information architecture with a focus on

Clear hierarchy prioritizing pollen at-a-glance
Building the app to be flexible and scalable
Intuitive navigation for tracking, forecasting and reports

Homepage

  • Grasp pollen levels and health impacts.

  • Identify local pollen species.

  • Plan today and tomorrow.

Symptom tracking

  • Log/track symptoms effortlessly.

Live impact & results

AllerTrack launched successfully on Google Play (June 2025) and App Store, achieving 100+ Android downloads in its early phase despite a rapid 1-month timeline. The design's clean, intuitive interface - featuring hyperlocal pollen dashboards, quick symptom logging, and customizable forecasts drove immediate user engagement in the competitive weather category.​

Downloads

1k+ on Android; iOS traction building post-launch.​

Feature Adoption

Recent updates added Symptom Module (weekly reports, sharing), boosting retention through personalized insights.​

User Trust

Privacy-first design (encrypted data, no third-party sharing) fosters habit-forming daily use.

Takeaways

This project was definitely a roller-coaster ride. From understanding the inception of the idea to executing it, I learnt a lot about how people think. This was also my first ever attempt at designing a mobile-app, so the learning curve was at an all-time high.

01
Setting up user goals before wireframing helped the team align on the requirements and what is expected outcome of each screen
02
Aligning with tech on their feasibility and providing solutions that help manage deliverables with strict timelines
03
Overcoming the challenge of information-dense screen to minimal, clean intuitive screen
04
Purposefull use of colour in design

If you like what you see, let's get in touch.

Let the conversations flow, and bloom.
