Checklists Manager

Checklists Manager is for lists with checkboxes. Create as many lists as you need, add tasks, mark them as done and reorder them by dragging. Everything is saved in your browser, with no account or server, and it works offline.

What you can do

• As many lists as you want. Shopping, work, moving house, recipes, guest lists. There is no imposed limit and each list is independent.
• Tasks with state. Add, edit, delete and mark each task as complete or pending. Completed items are crossed out at a glance.
• Reorder by dragging. You decide the order of both lists and the tasks inside them.
• JSON backup. Download a file with everything and load it again when you change device or browser. It is the only copy: if you clear your browser data, it is lost.
• HTML export. Download your lists as an HTML document to print or send to someone who does not use the app.
• Eight themes and colours. Change the look of the app with eight themes and assign a background colour to each list to tell them apart.

When to use it

It is designed for the moment when a note with bullet points is no longer enough: the supermarket shopping list, the steps of a process, the tasks of a move. Marking things done is the part that helps most, because at a glance you know what is left.

An important warning about your data

Because the information lives in the browser, there is a risk worth knowing: if you clear your browsing data, use private mode or change browser, the lists disappear. That is why the JSON backup is not an extra: use it from time to time, especially before changing any browser settings.
