Capture first, organize later. Fast To-Do is built around one idea: getting a thought out of your head should take one second. The input is the hero — type it, hit Add, it's saved. Tags, due dates and reminders come later, when you actually want to organize. CAPTURE-FIRST A prominent input on the home screen. No forms, no required fields, no friction. UNLIMITED SUB-TASKS Any to-do can nest under any other, as deep as you like. Press and hold the handle to drag items around and re-nest them. A tree view shows the whole structure, with collapsing. SWIPE TO ACT Swipe right to complete, left to delete. Completed items tuck themselves away automatically, and a tap brings them back. FLEXIBLE DUE DATES Be as vague or as precise as you want — a year, a month, a weekday, a specific day, or a day and time. Pick days from a real calendar. REMINDERS Get a notification before anything with a due date precise enough to pin a moment. On by default, and overridable per to-do. YOUR OWN TAGS The only categories are the ones you invent. Give a to-do any number of them, filter the list by tag, and see your stats broken down by tag. STATS Charts for completions over time, and by tag. Tap any bar to see the to-dos behind it. SHARE AS TEXT Send any to-do and its whole sub-tree as a clean indented checklist to Mail, Messages, Notes — anywhere. 8 LANGUAGES English, Arabic (full right-to-left), Chinese, Spanish, Italian, French, Portuguese and Hindi. TRULY OFFLINE, TRULY PRIVATE No account. No sign-up. No servers. Your to-dos live on your device and never leave it. No ads, ever. FAST TO-DO PRO A single one-time $1.99 purchase — never a subscription — unlocks tags and reminders. Everything else, including unlimited to-dos, sub-tasks and due dates, is free forever.
