Custom Analysis plots the trackables you choose on shared timelines so you can compare severity or occurrence across a week, month, or custom range. Open Reports → Custom Analysis—charts use only what you logged in the dates you select.
What Custom Analysis shows
- Line or bar charts for symptoms, life factors, and other trackables you pick—not the cycle-summary cards on Overview.
- Daily logs in the date range you choose; missing days show empty states instead of guessed values.
- Compare timing and severity across items on one screen when you log on Home or Daily Tracking.
Open Custom Analysis
01
Reports
Tap Reports in the bottom tab bar to open the Reports screen.
02
Custom Analysis
Tap Custom Analysis in the horizontal sub-tab selector under the Reports header. On first visit, a brief full-screen loading indicator may appear.
03
Timeframe pills
Weekly, Monthly, and Custom stay visible at the top while you scroll; after you scroll past the original row, a duplicate strip appears so you can change the range without scrolling back.
✦Quick start: Reports → Custom Analysis → pick Weekly, Monthly, or Custom → tap Select Items → choose trackables → Save.
Choose Weekly, Monthly, or Custom dates
01
Weekly or Monthly
Tap Weekly or Monthly, then choose a date-range chip in the horizontal scroller below the pills.
02
Custom
Tap Custom; until you pick dates, the label reads Select custom range. After you confirm, it shows start and end in short month-day form. Tap Custom again while selected to reopen the picker.
03
Custom range sheet
The date picker opens as a large sheet you cannot swipe away—confirm or cancel to close. Earliest date comes from your cycle history; latest is the end of the current month. Same-day ranges are allowed.
04
Expand control
On smaller screens, use the expand control on the timeframe row to show the full Weekly, Monthly, and Custom pills.
✦Charts are only as complete as your logs—track on Home or Daily Tracking during the weeks you analyze so lines and bars reflect real patterns.
Select items in the filter sheet
01
Select Items
Tap the circle filter button on the chart controls row to open the Select Items sheet.
02
Search
Type in the search field to find trackables by name, or expand Choose from categories and use tracking-type pills to narrow the list.
01
Choose from categories
Expand a category to see value-type hints (numeric, boolean, or mixed) and severity or occurrence summaries; use select-all to pick every item in that category.
02
Selected items
Review the count at the top; tap Clear all to start over. See all and See less appear when many pills are shown; No items selected appears when the list is empty.
03
Save
Tap Save to apply your selection—Save stays disabled until at least one item is chosen. Cancel closes the sheet without applying changes.
04
Pinned selection chip
After you save a custom item pick (not a group), a leading chip on the main screen restores it—the label shows the first item name and a more-items suffix when you chose several.
Preset group chips on the main screen
- When groups exist, a horizontal scroller shows chips such as Most Frequent 5, Most Severe 5, DSM-5 PMDD Symptoms, or groups you created—tap one to load its items into the charts.
- Predefined groups recompute from logs in the current date range and may disappear when empty.
- On first visit, the app applies your last saved group, or Most Frequent 5 when date ranges initialize.
- To switch groups, tap a different chip. To clear a group without picking another, open Select Items and tap Clear all—the main-screen chips do not deselect when you tap the same chip again.
Create and edit groups in Select Items
01
Groups section
In the Select Items sheet, scroll to the groups row. Tap a group pill to select it; tap the same pill again to deselect that group.
02
Edit mode
Tap the pen icon to enter edit mode—predefined groups dim, and a dashed Create group pill appears. Tap Done to exit edit mode.
03
Create or edit
Tap Create group or an existing user group, name it, pick items in the manage-group sheet, then tap Save group.
04
Delete group
Delete group appears only for groups you created—not for predefined chips.
Chart layout — By item or By category
- Open the chart grouping menu on the filter row and choose By item or By category. The menu is hidden when the DSM-5 PMDD Symptoms group is active.
- By item — with two or more numeric trackables selected, a combined overlay chart appears at the top (Severity trends over time or Daily symptom bars), and separate per-item rows appear below. With one numeric trackable, or for boolean trackables, charts use separate rows only.
- By category — one combined chart per tracking category in your selection, titled with the category name or an uncategorized label.
Line vs bar chart style
- Use the chart-style dropdown on the filter row to switch every Custom Analysis chart between line and bar at once.
- Combined line view has no five-series cap—use the legend to focus on the trackables you care about.
- Combined bar view shows at most five numeric series at once—the app ranks visible bars by how many data points each item has in the selected range.
Chart layout — DSM-5 PMDD Symptoms group
When you select the DSM-5 PMDD Symptoms group, the app replaces By item and By category with one combined chart per DSM-5 criterion. The chart grouping menu is not shown in this mode.
01
Line or bar (one chart)
Some grouped criterion or category charts show a second line/bar control in the chart body—that changes only that chart, not the filter-row style.
Read and interact with charts
01
Legend
Tap a legend item to show or hide that series. Phase hint bars appear along the x-axis on applicable charts.
02
Chart
Tap a point or bar for a tooltip. Pinch or double-tap to zoom the horizontal timeline—there is no labeled Reset zoom control in the shipped UI.
Bar chart limits
- Combined bar view shows at most five numeric series at once—the app ranks visible bars by how many data points each item has in the selected range.
- If you try to show a sixth bar via the legend, the legend pulses and a brief hint explains the limit; hide another series first to swap one in.
- Combined line view has no five-series cap—use the legend to focus on the trackables you care about.
- Boolean trackables always appear in separate rows; line and bar styling applies to numeric series only.
Empty, loading, and no-data states
- No items selected: the chart area explains that you need trackables—open Select Items from the filter button on the main screen (the empty state shows guidance text, not a separate action button).
- No data in range: items are selected but nothing was logged in the chosen window—try a wider custom range or log more days on Home or Daily Tracking.
- No tracking ever: you have no history yet—start logging before expecting charts here.
- Load failure: if chart data cannot load, red error text may appear in the chart area—try changing the date range or reopening Custom Analysis.
✦Comparing items on one timeline can reveal timing patterns you may want to discuss with a clinician. Charts summarize what you logged—they do not prove causation, diagnose PMDD, or replace a PDF export for clinical visits.
