Tack List

Tack is a quick, no-fuss task app for iPhone and iPad. If you use Obsidian, it can keep every task as a markdown file in your vault; without a vault it is a complete task app on its own.

ONE LINE, DATE INCLUDED
Type a task the way you'd say it and Quick Add picks out the due date and the tags:
• "Buy milk tomorrow 5pm #groceries"
• "Call the bank in 3 days"
• "Send the invoice next friday"
• "Stand-up at 9:30"

REMINDERS
Tack notifies you when a task comes due. Tick it off before then and you won't hear about it. Reminders can be switched off in Settings.

TODAY, INBOX, LISTS, STATS
Today shows what's due today. Inbox holds everything you haven't put in a list yet. Lists are yours to create. Stats shows your streak and the tasks you finished over the last 14 days.

OBSIDIAN
Pick your vault folder and Tack writes each task as a markdown file with YAML frontmatter (title, status, due date, tags, list) in a tack/ folder. Change a task in Tack and its file is updated within seconds; edit the file in Obsidian and the change comes into Tack the next time you open it. Properties you add in Obsidian are kept, and the files stay plain markdown whether or not you keep using Tack.

WIDGETS
Today (small, medium, large), Inbox and Stats (small, medium) for your Home Screen, updated as soon as you change something in Tack.

SIRI AND SHORTCUTS
Say "Add to Tack", then the task: "pay rent tomorrow 9am".
Say "Mark done in Tack", then the task's name.

PRIVATE
No account, no ads, no tracking, no server. Your tasks stay on your device, and in your vault if you connect one.

Light and dark appearance: follows your device, or pick one in Settings.
