About

tagTodo

Features
Read full description

tagTodo is a privacy-first task manager built on one idea: **everything is a tag.** There are no lists, folders, or projects to file things into. A task is just a title and a few tags — #work, #urgent, #waiting, #p1, @home, or a person's name. A task can belong to many contexts at once, so you never have to choose the "one right place" for it. You organize by **querying** the set of tasks with a tiny but powerful set-algebra language: • #today & #open — what's due today and not done • #work & #open & ~#waiting — open work you're not blocked on • (#work | #personal) & #week — this week, across contexts • #p1 & #overdue — high-priority tasks past due • #done & #week — a weekly review of what you finished Operators are simple: & (and), | (or), \ (except), ~ (not), and parentheses. Two tags side by side also mean "and". Save any query as a smart list and see its live count update as you work. AUTOMATIC TAGS Some tags are added for you and usable in any query — no typing required: #open, #done, #overdue, #today, #tomorrow, #week, #nodate, #all, plus time tags from each task's date (#2026, #JUN, #Q2, #FRIDAY, #WEEKEND, #SUMMER…). SEE THE STRUCTURE OF YOUR WORK Every query result comes with a summary (total / open / done / completion % / overdue), an area-proportional Venn diagram of its most common tags, and charts for throughput, created-vs-completed, and your open backlog over time. PRIVATE BY DESIGN All data stays on your device. No account, no ads, no tracking. Export and import your tasks any time as JSON or CSV. BILINGUAL Fully available in English and Vietnamese. tagTodo Pro (optional) unlocks unlimited tags per query. A 7-day free trial is included; monthly, yearly, and lifetime options are available.
