Lycana Is Now on Android: Everything You Need to Know

Lycana Comes to Android

Since launching on iOS, the most frequent question we have received is: "When is it coming to Android?" Today, we are excited to share that Lycana is now available on the Google Play Store.

This is not a quick port or a web wrapper. Lycana for Android is a fully native app built with Jetpack Compose and Material 3, designed to feel at home on Android while sharing the same core logic that powers the iOS app through Kotlin Multiplatform.

What Is Included

Symptom Tracking

The same comprehensive symptom tracking system from iOS, adapted for Android:

• Daily check-ins — log your symptoms, energy level, mood, and medications in under a minute
• Body map — the 16-zone interactive body map for pinpointing where symptoms are hitting
• Custom symptoms — track what matters to you, not just a pre-set list
• Severity scales — consistent 0-10 scales for tracking changes over time

Flare Risk Score

Lycana's signature feature — a 0-100 flare risk score that learns your personal patterns and helps you see flares approaching before they hit. The score is calculated using your symptom history, trends, and the pattern recognition engine in our shared Kotlin Multiplatform core.

Luna AI Coach

Luna, your AI-powered lupus companion, is available on Android powered by Gemini Nano through ML Kit GenAI on supported devices. On devices that do not support on-device AI, Luna uses a comprehensive template-based response system that draws from the same medical knowledge base.

Luna can help you:

• Understand your symptom patterns
• Prepare for doctor appointments
• Make sense of your trends over time
• Answer common lupus questions with evidence-based information

Nutrition Tracking

Log meals, track anti-inflammatory foods, and see how your diet correlates with your symptoms over time. The nutrition module includes lupus-specific guidance on foods that may help or worsen inflammation.

Lab Tracking

Enter your blood test results and track trends in key lupus markers over time — ANA titers, complement levels, anti-dsDNA, CBC, and more. Visualize how your labs correlate with how you feel.

Doctor-Ready Reports

Generate PDF summaries of your symptoms, medications, and trends to bring to your rheumatologist. No more walking into appointments and trying to remember what happened over the last three months.

Health Connect Integration

On Android, Lycana integrates with Health Connect — Google's centralized health data API. This means Lycana can read data from your fitness tracker, smartwatch, or other health apps (with your permission) to incorporate:

• Step count and activity data
• Sleep duration and quality
• Heart rate trends

This data feeds into your overall health picture and contributes to the flare risk score.

Health Connect uses a polling-based model, so Lycana checks for new data periodically rather than receiving real-time updates. You control exactly what data Lycana can access through Health Connect's granular permissions.

Built for Android, Not Ported From iOS

We took a platform-native approach to the Android app:

• Jetpack Compose — modern declarative UI that follows Android design patterns
• Material 3 — Material You design language with a custom Lycana color scheme
• Dark theme — designed dark-first for photosensitivity-friendly viewing, matching our iOS approach
• Android navigation patterns — bottom navigation bar, back gesture support, and system integration that feels natural
• Adaptive layouts — works across phones and tablets

The app shares its core domain logic with iOS through Kotlin Multiplatform — the flare risk engine, SLEDAI estimation, schedule optimization, pattern recognition, and achievement system are all shared code backed by over 300 tests. The UI and platform integrations are fully native.

Privacy: The Same Standard as iOS

Our privacy commitment does not change by platform:

• All AI processing is on-device — Gemini Nano runs locally, no cloud calls
• No account required — use Lycana without providing an email or personal information
• AES-256 encryption — your health data is encrypted on your device
• No analytics tracking — we do not track your behavior or sell your data
• We cannot access your data — the architecture makes it technically impossible for us to see your health information

Lupus data is sensitive. It includes your medications, your symptoms on your worst days, your fears about the future. That data deserves infrastructure built around respect, regardless of which phone you use.

Requirements

• Android 9 (API 28) or later
• Health Connect support requires Android 14+ for the best experience (available as a separate app on Android 9-13)
• Gemini Nano on-device AI requires supported devices with Android 14+ (Luna's template system works on all supported Android versions)

Get Started

Lycana for Android is available now on the Google Play Store. It is free to download with no account required.

If you have been managing your lupus without structured tracking tools because you are on Android, that barrier is gone. Your patterns are waiting to be discovered.
