Get Cycle Start Dates, Flow Level & Symptoms from Any Period Tracker Screenshot
Typing each cycle's start date, flow level, and symptoms from a period app into a health log takes 2-3 minutes per cycle — this pulls the same data from a single screenshot in 5 seconds.

What You Can Pull from a Period Tracker Screenshot
Period tracking apps display cycle data in calendar grids with color-coded dots, icons, and small date labels. With Custom Column Extraction, you name the fields you need and the AI locates them by understanding what each visual element means, not where it appears.
The first day of your period, marked on the calendar grid. Clue uses a dot, Flo shades the cell, Apple Health uses a red highlight — the AI reads the marker regardless of the app.
Total days from period start to the next. Some apps show this in a summary card; others require comparing dates across the calendar. The AI calculates the interval from visible date markers.
Light, medium, or heavy, shown as color-coded dots or shading. No text label — just visual indicators. The AI maps dot size and opacity to a Flow Level column.
Most apps render symptoms as icons (lightning bolt for cramps, brain for headache) rather than text. The AI reads the icon and maps it to a structured symptom name.
BBT readings from the temperature chart or log entry, if visible on the screenshot. Flo and Apple Health display this as a line chart — the AI reads numeric labels when rendered on the chart.
Mood tags (happy, sad, anxious) or free-text notes. Some apps use emoji, others use text labels — the AI reads both and maps them to a Mood column.
Period Trackers Store Your Data in a Walled Garden — Screenshots Are the Only Way Out
Clue, Flo, and Apple Health each display the same cycle data in completely different visual languages — calendar grids, color-coded dots, icon-based symptom trackers, and BBT chart overlays. The data is there, but the apps are designed to keep it inside. Semantic extraction reads the visuals by understanding what each element means.
Why Period Tracker Data Is Hard to Get Out
Export features are limited or broken. Clue requires emailing [email protected] to request a data export — no self-service. Flo JSON export strips all graphical information, losing icon-based symptoms. Apple Health XML export produces a file that Reddit users describe as "a massive file that no normal app can read."
Symptoms are icons, not text. A lightning bolt means cramps, a brain means headache. Traditional OCR reads individual characters — it sees a zigzag line, not a symptom label. Without semantic understanding, the icon has no meaning.
Calendar grids span multiple months with no sequential list. A single screenshot may show November through January on a calendar grid. The date numbers are small digits in individual day cells — not a sequential list. Traditional OCR reads scattered text fragments, not a structured date range.
How Semantic Extraction Reads Cycle Data from Any App
Name the columns — AI finds values by meaning, not position. Type "Cycle Start Date, Flow Level, Symptoms, BBT." The AI reads the calendar grid to locate the first day marker, interprets dot size and opacity as flow level, and maps the lightning bolt icon to "Cramps" — all without being told where each field sits on the screen.
One column set across Clue, Flo, and Apple Health. Upload screenshots from three different period trackers in one batch. The AI adapts to each app visual language — Clue dot-based calendar, Flo shaded day cells, Apple Health red highlight — and fills the same columns. Every screenshot becomes a row in one spreadsheet.
No account needed — works from the screenshot alone. The AI reads visible data directly from the image — no API access, no login, no support ticket to Clue or Flo. Just the pixels.
From a Period Tracker Screenshot to a Clean Cycle Log in Three Steps
Upload Your Period Tracker Screenshot
You have a screenshot from Clue showing your cycle history as a calendar grid with color-coded dots, or a Flo summary card with symptoms listed as icons, or an Apple Health cycle tracking view with BBT chart overlay. Any of these — drag them into the upload area. JPG, PNG, or WebP, full resolution or shared from a friend phone.
Name the Fields You Need
Type the column names: Cycle Start Date, Flow Level, Symptoms, BBT, Mood. The AI reads the calendar grid to locate the first day marker, interprets dot size as flow level, maps the lightning bolt icon to "Cramps," and reads the BBT numeric label from the temperature chart overlay — all from one screenshot. One column set, one batch.
Download a Structured Cycle Log
Processing takes about 5 seconds per screenshot. The output is one XLSX or CSV file: each row is one cycle entry, with columns for start date, length, flow level, symptoms, BBT, and mood. Batch several months of screenshots together and get a complete history in one export. Roughly 24x faster than typing each cycle by hand (~2 min manual per cycle vs ~5s here).
When It Works Best — and When to Be Cautious
Understanding these boundaries helps you get consistent results for cycle data extraction.
When It Works Best
Full-resolution screenshots of period tracker calendar views. Machine-rendered cycle markers and symptom icons achieve up to 99% accuracy.
Screenshots with visible text labels alongside icons. Apps that show both an icon and a text label produce the most reliable symptom extraction.
Cross-app batch processing with one column set. Upload Clue, Flo, and Apple Health screenshots together. One column set produces a consolidated cycle log.
When to Be Cautious
Compressed or forwarded screenshots. Screenshots shared through messaging apps lose resolution — small date digits and icons become harder to distinguish. Direct screenshots produce better results.
BBT charts without visible numeric labels. If the screenshot shows only a line chart overlay with no temperature values displayed as text, the AI cannot extract the numbers. Screenshot the detailed log view where BBT appears as a paired label-value.
Visible data only — no clinical interpretation. The tool extracts what the app displays on screen. It does not interpret cycle patterns or provide medical analysis. Share your log with a healthcare provider for review.
Frequently Asked Questions
Can I extract cycle data from a screenshot of Clue or Flo without having an account on either app?
Yes. Screenshot extraction works from the image alone — no account access, API connection, or export request needed. Whether the screenshot is from your own phone or a photo of someone else device, the AI reads the visible calendar grid, date markers, and symptom icons directly from the image. This is the only way to get cycle data from an app you do not have a login for.
How does the AI read flow level indicators when the app uses color-coded dots instead of text labels?
The AI interprets color-coded indicators by context on the calendar grid. Clue uses a dot of varying intensity — darker means heavy flow, lighter means light flow. Flo shades the day cell with different opacity levels. The AI maps visual density to Flow Level (Light, Medium, Heavy). If the app also shows a text label, the AI reads both.
Can I extract basal body temperature readings from a BBT chart overlay in Apple Health or Flo?
If the BBT value is displayed as a visible label on the chart — a tooltip showing 36.7°C or a log entry with the temperature — the AI reads it. If the screenshot shows only the line chart without numeric labels, temperature values cannot be extracted. For best results, screenshot the detailed log view where BBT appears as a paired label-value.
Can I batch process screenshots from different period tracking apps together?
Yes. Define one set of columns — Cycle Start Date, Flow Level, Symptoms, BBT, Mood — and upload Clue, Flo, and Apple Health screenshots into the same batch. The AI processes each screenshot independently, adapting to each app visual language. The output is a single spreadsheet with one row per screenshot. Fields that do not appear on a particular screenshot stay empty.
What if my period tracker app uses only icons for symptoms — will the AI understand what the lightning bolt and brain icons mean?
Yes. The AI maps the lightning bolt icon to "Cramps," a brain to "Headache," a belly to "Bloating," and a teardrop to "Spotting." Icons are mapped to standard symptom names across app conventions. If the app uses a non-standard icon, the description is placed in a Notes column instead.
