myhairline.ai works on both iOS and Android with an approximately 68% iOS and 32% Android user split across the platform. The core AI analysis is identical on both operating systems, but there are platform-specific differences in health app integrations, camera behavior, and browser performance that affect your tracking experience.
Core Features: Identical on Both Platforms
The features that matter most for hair loss tracking work exactly the same on iPhone and Android.
| Feature | iOS | Android | Notes |
|---|---|---|---|
| AI density analysis | Identical | Identical | Same ML model runs in browser |
| Norwood staging | Identical | Identical | Same classification algorithm |
| Facial landmark detection | 468 points | 468 points | MediaPipe runs client-side on both |
| Photo capture | Supported | Supported | Camera quality varies by device |
| Progress tracking | Full history | Full history | Stored in browser/local storage |
| Report export | PDF/Image | PDF/Image | Same export options |
| Privacy (local processing) | Yes | Yes | No server uploads on either platform |
The AI model that analyzes your photos uses MediaPipe's facial landmark detection, which runs as a client-side web application. Your browser processes the image locally regardless of whether you are on Safari, Chrome, Firefox, or any other browser. The Norwood staging algorithm, graft estimation calculations, and density measurements are all platform-independent.
Platform-Specific Differences
Health App Integrations
iOS: Apple Health. myhairline.ai can read and write data to Apple Health on iPhone. This allows you to log health metrics like weight, sleep data, and activity levels alongside your density tracking. If you are monitoring whether lifestyle factors correlate with hair density changes, this integration pulls relevant health data into your tracking timeline automatically.
Android: Google Fit. The equivalent integration for Android connects myhairline.ai with Google Fit. The data types available are similar: activity, weight, sleep, and general health metrics. See our guide on Google Fit hair tracking integration for setup instructions.
Both integrations are optional. The core density tracking works without either health platform connected.
Camera and Photo Quality
Camera hardware varies more across Android devices than iOS devices. This affects photo quality, which in turn affects analysis accuracy.
iOS considerations:
- iPhone cameras are consistent across models within 2 to 3 years
- Portrait mode on recent iPhones may interfere with analysis (use standard photo mode)
- TrueDepth camera on front-facing shots provides consistent lighting assessment
Android considerations:
- Camera quality varies significantly between manufacturers and price points
- Samsung, Google Pixel, and OnePlus flagship cameras perform comparably to iPhone
- Budget Android phones (under $200) may produce lower-resolution images that reduce analysis precision
- Some Android camera apps apply aggressive post-processing that can alter hair appearance in photos
Recommendation for both platforms: Use the rear camera with someone else's help for the most consistent results. Front-facing cameras work but introduce more variability in distance and angle. Avoid beauty filters or portrait mode.
Browser Performance
myhairline.ai runs as a web application, so browser choice affects performance.
iOS:
- Safari delivers the best performance on iPhone (all iOS browsers use WebKit)
- Chrome on iOS works well but uses the same rendering engine as Safari
- Analysis processing time: typically 2 to 4 seconds on iPhone 12 or newer
Android:
- Chrome is recommended for the best experience
- Samsung Internet Browser also performs well
- Firefox on Android works but may be slightly slower for ML inference
- Analysis processing time: 2 to 6 seconds depending on device processor
| Browser | iOS Performance | Android Performance |
|---|---|---|
| Safari | Best (native) | N/A |
| Chrome | Good (WebKit on iOS) | Best (recommended) |
| Samsung Internet | N/A | Good |
| Firefox | Good | Adequate |
Storage and Data Persistence
iOS: Safari's Intelligent Tracking Prevention (ITP) may clear local storage data after 7 days of inactivity. If you do not visit myhairline.ai for more than a week, your tracking history stored in local storage could be affected. Export your data regularly or use the cloud sync feature if available.
Android: Chrome on Android retains local storage data more reliably than Safari on iOS. However, clearing browser data or using incognito mode will erase tracking history. Do not use incognito/private browsing mode for density scans you want to keep.
How to Get the Best Results on Each Platform
Step 1: Choose the Right Browser
On iOS, use Safari. On Android, use Chrome. These browsers provide the fastest ML inference and most reliable local storage for tracking data.
Step 2: Configure Camera Settings
Turn off any AI-based photo enhancement, beauty mode, or HDR processing before taking scan photos. These post-processing features can alter the appearance of your hairline and scalp, reducing the accuracy of the density analysis.
On iPhone, use the standard Photo mode (not Portrait). On Android, check your camera app settings and disable any automatic beautification.
Step 3: Set Up Health Integration (Optional)
If you want to correlate health metrics with density tracking:
- iPhone: Go to myhairline.ai settings and enable Apple Health integration. Grant read access to the health categories you want to track alongside density data.
- Android: Go to myhairline.ai settings and enable Google Fit integration. Authorize the connection and select relevant data types.
Step 4: Enable Notifications
Set a monthly reminder to take your density scan. Consistency in timing matters for accurate trend tracking.
- iPhone: Add a recurring calendar event or use the Reminders app
- Android: Use Google Calendar or any reminder app to prompt monthly scans
Step 5: Export Data Regularly
Regardless of platform, export your tracking data periodically. This protects against data loss from browser cache clearing, device changes, or storage limitations.
Switching Between Devices
If you switch from iPhone to Android or vice versa, your tracking history does not automatically transfer since it is stored locally in your browser. Before switching:
- Export your complete tracking history from the current device
- Set up myhairline.ai on your new device
- Import or manually reference your historical data for continuity
Your Norwood staging and density measurements will be consistent across devices because the AI model is the same. Only the local storage history needs manual transfer.
Start Tracking on Your Device
Whether you are on iOS or Android, the analysis experience is the same. Visit myhairline.ai/analyze from your phone's browser, take a photo, and get your Norwood stage and density reading within seconds. For more on setting up your complete treatment tracking workflow, see our detailed guide.
