Chronos

Read full description

Chronos organizes your work by process, not by loose lists. A process is the series of stages your tasks move through: Contact, Proposal, Close. You define it once and reuse it across every task you want. Each task knows which stage it's in and how long it's been there. WHAT YOU CAN DO Create processes with as many stages as you need, in any order. Add substeps inside each stage for finer detail. Mark stages and substeps as parallel or sequential. You can mix both in the same process. Move a task forward step by step: each tap completes what's next and jumps blocks when the stage is done. Track which days you worked on each task. Add dated comments as you go. See how long each stage and substep took. SORTING Sort your list by age, by process and stage, or by process, stage and age. Tasks group under their process when you need it, and you can tag them to separate by client, urgency or team. COMPLETED TASKS When you close a task it leaves the list and gets archived with its full history: when it was created, when it closed, how long it stayed open, the days you worked on it, the time per stage and every comment. WIDGETS Four home screen widgets: worked today, worked today by process, all pending tasks, and each process with its open tasks. APPEARANCE Four themes: two light ones on a cream base and two dark. They apply to the widgets too. SYNC Your processes and tasks sync between iPhone and iPad with iCloud. Everything works offline and catches up when you're back. NOTIFICATIONS Pick the weekdays and time you want to be reminded, per task. FREE AND PRO Free: up to 4 tasks and 3 processes, with every feature available. Pro: unlimited tasks and processes. Monthly or yearly subscription. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

PlanTodo — A Smarter Way to Manage Tasks and Recurring Plans PlanTodo is a cross-platform to-do app designed for multiple devices. It doesn’t just help you track tasks — it helps you automatically plan the future. Unlike traditional to-do apps, PlanTodo clearly separates Tasks and Plans: - Tasks: one-time to-dos - Plans: rule-based systems that continuously generate tasks You can use it as a simple to-do list, or unlock its full power by letting recurring work take care of itself. --- Flexible and Powerful Planning System PlanTodo goes far beyond typical recurring task features: Basic Rules - Daily / every n days - Specific weekdays (e.g., Monday, Friday) - Fixed dates each month or year Advanced Rules - The last Saturday of each month - The second Monday every two months - The nth day from the end of the year Advanced Automation - Trigger based on other plans (e.g., 3 days before another plan) - Multi-level dependencies (plans can trigger one another in chains) - Combined conditions (trigger when any or all conditions are met) Fine-Grained Control - Exclude specific dates - Automatic postponement (e.g., skip workdays and trigger on the next non-working day) - Auto enable / disable / delete - Sleep cycles (skip a set number of triggers before activating) Set up complex long-term schedules once, and let them run automatically. --- Efficient Task Management Everything you expect from a modern task manager: - Add, edit, duplicate, delete, and restore tasks - Rich attributes: date, start time, reminders, duration, color, and more - Supports subtasks, allowing complex tasks to be broken down for step-by-step progress while maintaining an overall view. - Supports task timer to track the actual time spent on tasks from the task details page. Tasks generated by plans eliminate the need to repeatedly create the same items. Tasks can also inherit parent-child relationships from plans. With the timeline enabled, you can quickly identify time conflicts through the red sections and find available time through the transparent sections, helping you arrange tasks more efficiently. A current time indicator on timeline clearly shows daily progress and the flow of time. --- Progress Tracking Without Pressure PlanTodo focuses on cumulative progress, not daily perfection. For example: - Set a goal like “Read for 30 minutes a day” - Completing 20 minutes isn’t a failure — the gap is recorded - Catch up later to stay on track overall This approach makes long-term goals more sustainable and less stressful. Supports tracking by both time spent and completion count. Three charts are available to help you track your progress: Balance, Total Completed, and Daily Completed, giving you a clear and intuitive view of how your progress changes over time. --- Multi-device sync Privacy-first, local-first. * End-to-end encrypted * Only your devices can read your data * Even the server can't decrypt it --- Clippings Clippings are for saving a sentence or a URL. * Save on the go. When you find something interesting on your phone, share it directly to PlanTodo to save it as a clipping. * Collect with ease. Set up automatic categorization rules for clipping categories, and let PlanTodo fetch page titles from URLs automatically. * Turn clippings into action. Link a plan’s description to a clipping category, and daily tasks will pull in relevant clippings. For example, a foreign-language vlog URL can appear directly in your task, so you can get started without searching for it again. Import and export clippings in bulk. Every now and then, export your saved article URLs and open them all in your browser with One Click Open. Set aside a solid block of time for an immersive reading session. --- Website: https://plantodo.app/
