How Task App Works

Task App uses a mathematical priority algorithm to automatically rank your tasks by what matters most right now. It combines importance, urgency, deadline proximity, task aging, and estimated duration into a single priority score — so you always know what to work on next.

The Priority Algorithm

Every task is scored using this formula:

Score = (Importance + Urgency + Aging - Duration Penalty) × Hard Deadline Multiplier × Escalation Factor

Importance

High (3×), Medium (2×), or Low (1×) multiplied by a base score. Configurable weights in Pro.

Urgency

Overdue tasks score highest and grow daily. Future tasks decay exponentially as the due date approaches. Due-today tasks get a fixed boost.

Aging

Tasks earn priority points for every day since they were assigned. Old tasks gradually rise so nothing gets permanently buried.

Duration Penalty

Longer tasks receive a small penalty, nudging shorter quick-win tasks upward. This helps you build momentum.

Hard Deadline

Tasks flagged as hard deadlines get a 1.5× multiplier, ensuring non-negotiable items always surface.

Escalation

Manually set an escalation factor on any task to override normal ordering when you know something needs attention.

All Features

Mathematical Priority Algorithm

Every task gets a numerical priority score calculated from importance, urgency, deadline proximity, task aging, and estimated duration. No guesswork — the algorithm tells you exactly what to work on next. Pro users can customize all weights.

Location-Aware Smart Suggestions

The Up Next view filters tasks by your current location and available time window. It accounts for travel time between locations so you only see tasks you can realistically complete right now.

Bring Your Own AI Key

Connect your own API key from OpenAI, Anthropic, Google Gemini, Groq, Mistral, and 5+ more providers. AI auto-categorizes tasks and estimates durations. Your key stays in your browser — it never touches our servers.

Visual Productivity Analytics

Track completion trends, workload distribution, overdue patterns, and weekly capacity with interactive charts. See week-over-week deltas and identify which projects and categories consume the most time.

Recurring Tasks & Hard Deadlines

Set tasks to repeat on flexible schedules with optional end dates. Mark hard deadlines to apply a 1.5x priority multiplier that automatically bumps critical tasks above everything else.

Project Organization

Group tasks into projects, organize projects into drag-and-drop groups, and track completion progress with visual indicators. Duplicate projects as templates for repeating workflows.

Escalation & Quick Wins

Manually escalate tasks that need attention with a custom multiplier. The algorithm also applies a small duration penalty so shorter tasks naturally surface — encouraging quick wins that build momentum.

Task Aging

Tasks that have been sitting in your list gradually rise in priority over time. This prevents old tasks from being permanently buried under new urgent work.

CSV Import & Export

Export your full task data to CSV for analysis in spreadsheets or other tools. Import tasks from CSV to bulk-add work items.

Dark & Light Themes

Full dark mode and light mode with CSS variable-based theming. Respects your system preference or set it manually.

Offline-First PWA

Works offline as a Progressive Web App. Install it on your phone or desktop. Changes sync automatically when you reconnect.

Frequently Asked Questions

How does the priority algorithm work?

The algorithm calculates a numerical priority score for each task based on five factors: importance level (High/Medium/Low with configurable multipliers), urgency (overdue tasks score highest, with exponential decay for future due dates), task aging (older tasks gradually rise in priority), a duration penalty (shorter tasks get a slight boost to encourage quick wins), and multipliers for hard deadlines and manual escalation. The formula is: (Importance + Urgency + Aging - Duration Penalty) x Hard Deadline Multiplier x Escalation Factor. All weights are customizable in the Pro plan.

What AI providers are supported?

Task App supports bring-your-own API key for: OpenAI (GPT-4o, GPT-4, GPT-3.5), Anthropic (Claude), Google Gemini, Groq, Mistral, Together AI, DeepSeek, Fireworks AI, Perplexity, and local models via Ollama. Your API key is stored locally in your browser and sent directly to the provider — it never touches our servers.

Can I use Task App without an account?

Yes. Guest mode gives you full access to task management, the priority algorithm, and all views. Your data is stored locally in your browser. Create an account when you want cloud sync across devices.

How much does Task App cost?

Core task management is free. The Pro plan costs $2/month or $12/year and unlocks full algorithm customization and AI-powered features like auto-categorization and time estimation.

How are location-aware suggestions different from a normal task list?

The Up Next view filters your prioritized tasks by your current location and available time. If you have 30 minutes at the office, it shows only office tasks that fit in that window — sorted by priority score. It factors in travel time between locations so you always see tasks you can realistically complete right now.

What analytics does the Overview page provide?

The Overview shows: tasks completed this week and month with week-over-week trends, overdue task counts, upcoming deadlines, total workload in hours, completion activity charts broken down by category, workload distribution pie charts, top projects by pending tasks, and weekly capacity analysis. All charts support configurable time ranges.

Does Task App work offline?

Yes. Task App is a Progressive Web App (PWA) that works offline. When you reconnect, changes sync automatically with Firestore.
