DoOne

Product Introduction

1. Definition: DoOne is a native iOS and iPadOS productivity application that combines a structured task management system with a dedicated focus timer. It is technically categorized as a personal task manager and Pomodoro-style focus timer application.
2. Core Value Proposition: DoOne exists to combat task-switching and fragmented workflow by enforcing a "single-task focus" methodology. Its core value proposition is to help users, especially power users and knowledge workers, deep work by planning their day in three simple lists and then committing to one task at a time with a built-in, actionable timer.

Main Features

1. Tri-List Task Planning: The app structures task management into three primary lists: Today, Next, and Someday. This creates a clear hierarchy, allowing users to plan immediate actions while parking future ideas, reducing cognitive load and decision fatigue.
2. Integrated Focus Timer with Session Logging: Each task has its own dedicated focus timer. Starting a timer initiates a "focus session" for that specific task. The app logs all sessions per task, providing tangible data on time investment. The timer is highly accessible, running in a Live Activity, widgets, and Control Center for system-level visibility.
3. Native Platform Integrations & Automation: A key Pro feature is the ability to connect to external tools. DoOne offers direct integrations with GitHub, GitLab, Linear, and Todoist, and supports generic Webhooks for services like n8n or IFTTT. Users can complete a focus session and trigger actions like closing issues, adding labels, or updating tasks automatically.
4. Hardware-Optimized Design (iPhone Duo): The application features a unique, adaptive UI specifically engineered for the iPhone Duo's form factor. It intelligently reflows content around the hinge for three primary postures: fully open (split-pane view), tent mode on a table, and closed using the outer display for break countdowns.
5. Privacy-First Architecture & Offline Functionality: DoOne operates on a no-account, no-server, no-tracking principle. All data resides on-device. Optional iCloud sync (Pro feature) uses the user's personal Apple ID. Features like Brain Dump (voice-to-tasks using on-device Apple Intelligence) process audio locally without sending it to external servers.

Problems Solved

1. Pain Point: Overwhelming task lists and constant context-switching disrupt deep work and flow states. Traditional to-do apps often become dumping grounds, while separate timer apps lack task context.
2. Target Audience: The primary user personas are software engineers, developers, project managers, and technical creators who use tools like GitHub, GitLab, or Linear daily. Secondary audiences include students, writers, and any knowledge worker seeking a minimalist, focused workflow on Apple devices.
3. Use Cases:
   • A developer planning their day: reviewing PRs (Today), writing documentation (Next), and researching a new library (Someday). They focus on the PR review for 25 minutes, and upon completion, the session log is saved and a webhook updates the GitLab merge request.
   • A project manager using the iPhone Duo in tent mode on their desk, with the timer visible and task list accessible for quick reference during a deep work block.
   • A writer using Brain Dump to verbally capture article ideas that are instantly parsed into tasks in the Someday list, all processed on-device for privacy.

Unique Advantages

1. Strengths & Limitations (Pros & Cons):

   • Pros: Exceptional privacy model with on-device processing. Unique, thoughtful design for the iPhone Duo. Powerful, developer-centric integrations that automate workflows. Clean, opinionated UI that enforces focus. One-time Pro purchase with no subscription.
   • Cons: Platform-locked to Apple's iOS/iPadOS ecosystem. Lacks collaborative features or web/desktop client, making it strictly personal. Advanced features (sync, integrations) require Pro purchase. Brain Dump requires a device with Apple Intelligence.

2. Key Alternatives & Differentiation:

   • vs. Todoist + Separate Timer App: Todoist is a more powerful, cross-platform task manager but lacks a built-in, task-specific timer. DoOne integrates the timer directly into the task, creating a seamless planning-to-execution loop within a single, simpler interface.
   • vs. Focused Work Apps (e.g., Forest, Be Focused): These apps are primarily sophisticated timers with gamification or blocking features but have weak or non-existent task management. DoOne differentiates by offering a robust, structured task system as its foundation.
   • vs. Notion or ClickUp: These are all-in-one workspace platforms with immense flexibility but higher complexity and setup time. DoOne is a focused, opinionated tool that offers zero setup, instant use, and is optimized for the specific job of "pick one task and work on it."

Frequently Asked Questions (FAQ)

1. Is DoOne a subscription service? No, DoOne uses a one-time purchase model for its "Pro" upgrade. The core planning and focus timer functionality are free indefinitely. The Pro license is a single payment that unlocks iCloud sync, integrations, and other advanced features.
2. Does DoOne sync with Google Tasks or other Android apps? No, DoOne is exclusively built for the Apple ecosystem (iOS, iPadOS). It syncs via iCloud for Pro users and can integrate with web-based services like Todoist or GitHub via their APIs, but there is no Android or web app.
3. How do the integrations with GitHub and Linear work? After purchasing Pro, you can connect your accounts within the app's settings. When you complete a focus session for a task, you have the option to trigger actions (like "Close Issue," "Add Label") in the connected service. This typically uses OAuth for secure access.
4. Where is my task data stored? By default, all your task data is stored locally on your iPhone or iPad. If you purchase Pro and enable iCloud sync, your data is encrypted and stored in your personal iCloud account. The developer's servers are never involved in storing your tasks.
5. Can I use DoOne on my Mac? There is currently no native macOS application. However, you can potentially use the iPad version on Apple Silicon Macs via Mac Catalyst if the developer enables it, but the experience is designed for touch-first interfaces.
