Features
Checkje is a fast, smart task list. These are the main features and how they work.
Guided tour
The first time you sign in, a short tour points out the main parts: adding and opening a task, completing or planning ahead, lists and tags. You can skip it at any time.
Adding tasks
Click Add task above the list (or press ⌘/Ctrl+Enter) and type the title. The Today, Tomorrow and Date chips schedule the task right away: with a title present, picking a date creates the task immediately. Enter or ⌘/Ctrl+Enter again works too. The pencil icon opens the full editor, carrying over the title and date you already entered.
The full editor holds the rest: the list, a description, time, tags, recurrence, subtasks and a star for important tasks.
On mobile the + button opens the same quick entry as a bottom sheet.
A task added from All tasks lands in your default list. The full editor moves it to another list if you want.
Date view
Tasks are grouped by day: Overdue, Today, Tomorrow, then one group per date, with No date last. A recurring task that was scheduled ahead automatically stays hidden until its own day.
Sorting
The Sort menu sets the order within each group:
- Date and time (default): timed tasks first, then in creation order.
- Tag: tasks sharing a tag sit together, untagged tasks last.
- Alphabetical: by title, A to Z.
The choice is remembered and applies everywhere: inside a list, in the pinned Important section and in All tasks.
Tags
Tags are coloured labels that belong to you, not to a list. The same tag works across every list, so in All tasks one tag filters your whole task list. The Tags menu filters by one or more tags; Manage tags at the bottom of that menu creates or edits them.
In a shared list you both see the same tag name on a task. A name you don't have yourself shows without a colour; add it to your own tags and it takes your colour. Renaming or deleting a tag also applies to the other member's tasks in that shared list. Before deleting, Checkje shows how many tasks carry the tag and how many of those are in a shared list.
Important
Star a task and it appears in the pinned Important section, above the day groups.
Lists and sharing
Keep separate lists for work, home or a project. All tasks (⌘/Ctrl+I) sits on top of the list switcher: it holds the tasks from every list together, grouped by day, each with a badge for the list it lives in.
Move a task to another list with the List field in the full editor. The task takes its tags along: tags belong to you, not to a list.
Share a list with a share link: anyone with the link can join and edit its tasks. Links can be revoked at any time.
Assigning tasks
In a shared list you can give a task to one of its members, with the Assigned to field in the full editor. The task row names who it is for, and says For you when that is you. In a list you don't share the field isn't there: there is nobody to hand a task to.
Assignment also decides what All tasks holds: everything except the tasks assigned to somebody else. Those you only see when you open the shared list itself. So unclaimed work stays right in your overview.
When a task has a time, its reminder goes to whoever it is assigned to, in that person's own timezone. Handing over a task hands over its notification too. If the owner removes somebody from the list, their assignments fall back to nobody.
What the others see is the name from your profile. Leave it empty and they see the first part of your email address. Sign in with Google and your name is already there.
Recurring tasks
A task can repeat daily, weekly, monthly or yearly, with an interval ("every 2 weeks") or on fixed weekdays. Completing a recurring task schedules the next instance automatically; it stays hidden until its own day.
Sharing from Android
Install Checkje as an app ("Add to home screen" in Chrome) and Checkje shows up in Android's share sheet. Share a web page to Checkje and the task editor opens with the page title as the task and the link in the description. (iOS does not support this yet.)
Linking an email to a task
Paste a Gmail message link (the URL from the address bar) into a task's description. The task then shows an Email button that opens the message. Only the link is stored, never the mail's content; the message opens only for whoever has access to that mailbox.
Works with AI
Connect an AI assistant such as Claude over MCP to read and manage your tasks. See MCP server for the setup.
