What it does
PDA Day gives you a structured but flexible space to capture what matters — without requiring an account, a subscription, or an internet connection.
Inside the app
The Home tab shows today's tracking status for each person, recent daily records, and a full search interface. It's the daily starting point — one tap to log today or edit an existing record, plus search across every past entry by person, indicator, or event.
The Dashboard renders charts and summary widgets built from your Daily Records. Add, remove, and reorder widgets to focus on the indicators that matter most to you right now.
Add each person you track — a child, a partner, yourself. Record their name, neurotype (Externalized or Internalized PDA), special interests, and whether they're dopamine-bound or social-seeking. These profiles link to their daily records throughout the app.
Tracking Profiles are reusable templates that define which indicators to collect for a person each day. Create multiple profiles, import and export them as JSON, and assign them to people. When you start a new Daily Record, PDA Day uses the assigned profile to pre-populate the form.
Log notable events — school refusal, meltdowns, therapy appointments, successful outings, anything worth remembering. Events include a title, description, person, duration, and date, and can be linked to indicators in daily records for richer context.
Indicators are the building blocks of daily tracking. Each one has a name, description, and type: Activation, Connection & Trust, State of Regulation, or Observations. PDA Day ships with a default set, and you can create your own. Activation indicators can also be tagged to a Basic Need category — Eating, Sleep, Hygiene, Safety, or Toileting.
A constraint is a structural reality you cannot change in the present moment. Being a single parent, working full-time, having no nearby family support — these are constraints. Documenting them keeps your decision-making honest and grounded. Constraints can be exported and imported as JSON.
When facing a difficult choice, the Decisions tab walks you through a structured cost-benefit analysis that evaluates the nervous system impact on every person in the family — not just the person with PDA. It helps make the stakes visible and the tradeoffs explicit before you act.
