Custom Fields
Your work, as a
living database.
Build the fields your work actually needs, then point a project tab at your contacts, companies, tasks, or projects and each becomes a row. Your fields become the columns, and every column totals at the bottom. A real database, offline and private.
Capabilities
Your data, your structure
14 Field Types
Text, number, currency, date, dropdown, multi-select, checkbox, rating, progress, URL, email, phone, and relationship. Track any data your work needs.
Project Database
Point a tab at your contacts, companies, tasks, or linked projects and each becomes a row. Your fields become the columns. Edit any cell, total any column at the bottom. A real database, inside your project.
Relationship Fields
Link tasks, projects, contacts, and companies to each other. Two-way links keep both sides in sync, with backlinks that show exactly what connects to what.
Rollups & Financial Metrics
Sum, average, count, min, and max across linked entities. Tag currency fields with roles and PrimeTask derives 8 metrics automatically: Budget Health, Profit, ROI, Burn Rate, Runway, and more. 14 currencies, including BTC.
Templates & Setup Wizard
17 built-in templates plus a guided Setup Wizard scaffold a full field setup in a click. Save your own templates to reuse across Spaces.
Per-Space Configuration
Each Space has its own field set. A client Space tracks budgets and deal stages, a personal Space tracks habits. Switch Space, switch structure.
Project Database
Your project, every angle.
Point a tab at your contacts, companies, tasks, or linked projects, and each becomes a live table. Your fields are the columns, two-way relationships connect the rows, and totals roll up at the bottom. Mark a customer paid and project revenue rises. Track a supplier and margin updates live. Database power, project shape, running on your machine.
Cost Summary
And it does the maths.
Tag currency fields with roles like Budget, Expense, Revenue, or Payment, and PrimeTask rolls them into a live Cost Summary. Track Remaining to Pay, Budget Health, Profit, ROI, Burn Rate, and Runway, all computed from your own fields, in 14 currencies. No spreadsheet, no formulas.

The full toolkit
Custom Fields ship with PrimeTask Pro. Every field type, every integration - no add-ons.
Built for you
Perfect for
Freelancers & Agencies
Track billable rates, client budgets, and project costs with currency fields. Turn your task list into a financial dashboard without a separate tool.
Product Teams
Add priority scores, effort estimates, and feature categories to tasks. Filter and sort by any field to build your own triage workflow.
Researchers & Students
Track reading status, citation counts, or experiment results. Custom fields turn PrimeTask into a structured research database.
The difference
Not just metadata. Real structure.
Most task apps let you add a text note or a tag. That's not a custom field - that's a workaround. Real custom fields have types, validation, sorting, filtering, and aggregation.
PrimeTask's custom fields are proper structured data. A currency field knows it's money. A date field has a date picker. A dropdown field constrains choices. And all of it integrates with table view, Kanban badges, export, and database queries.
This is the flexibility of a spreadsheet with the usability of a purpose-built tool - and it all runs offline on your machine.
Your workflow. Your fields.
Structured data that lives on your machine.
Custom Fields are included in PrimeTask Pro - one purchase, every field type, no per-field or per-space fees.
