About PainCanvas

A focused pain journal built for real daily use

PainCanvas is a mobile app designed for people who need to track chronic pain, medication activity, flare episodes, and related context over time without handing their health data to a cloud service to do it.

All records are stored locally on your device. The app does not require an account, does not embed third-party analytics, and does not sync health data externally. When you want to share or review your data, you export it yourself.

PainCanvas dashboard showing today's summary, recent activity, and quick actions.

The app opens on a practical summary screen instead of a marketing shell or account dashboard.

Pain Logging

Log what happened, not just how bad it felt

Each entry captures pain severity on a structured scale, affected body regions on a front and back body map, contributing factors, free-form tags, and notes. You can associate a medication event directly with an entry so treatment context stays close to the symptom record.

Body-region selection on front and back maps
Structured entry details beyond a single pain number
Notes, tags, and factors for recurring situations
Optional weather snapshot, auto-filled via US National Weather Service or entered manually
Designed to make later review more useful

PainCanvas log screen with body map selection. — **Body map selection** Mark where pain is happening before you move on to the rest of the entry.

PainCanvas structured pain entry screen. — **Entry details** Capture severity, context, and supporting notes in the same flow.

Medications

Scheduled and as-needed medication tracking

Add medications as scheduled or as-needed, log each dose with a timestamp, and keep medication activity connected to symptom entries. That makes it easier to look back and understand what happened before and after a change.

Scheduled reminders and repeat routines
As needed logging for PRN medications
Follow up reminders after a dose
Medication history kept alongside pain records

PainCanvas medication list screen. — **Medication list** See tracked medications, schedules, and next actions from one screen.

PainCanvas export and share options screen. — **Review and export** Medication activity can be taken with the rest of your record when you export.

History and Review

Return to the timeline when details start to blur together

The history views are there for recall. You can revisit entries, compare days, and keep long-running issues from turning into disconnected fragments spread across memory, text threads, and appointment notes.

Chronological review of previous entries
Useful for follow-up visits and personal review
Built to support flare-oriented tracking over time
Helps connect symptoms back to treatments and context

PainCanvas history screen with prior pain entries. — **History list** Scroll through prior entries in order instead of piecing events together manually.

PainCanvas detail breakdown for a selected insight or data slice. — **Focused review** Open a narrower view when you want to inspect one slice of the timeline in detail.

Insights and Export

Spot patterns and share data on your terms

The insights screens turn daily records into trends, comparisons, and drill-down views. When you need to take your data elsewhere for a doctor visit or personal review, exports are available directly inside the app.

Trend charts and date-range review
Breakdowns by medication, factor, or region
Designed for self-review as well as appointments
Export records without requiring cloud sync

PainCanvas insights screen with charts and summary metrics. — **Insights overview** Review trends and summary metrics across a selected time window.
