## What is Checkstack?

Check off your habits, build streaks, and see every perfect day add up.

Checkstack is a calm, simple habit tracker that feels at home on your iPhone. Tap once to complete a habit, watch today's progress bar fill, and keep your streaks going — without accounts, ads, or clutter.

TODAY AT A GLANCE
• See "3 of 5 done" and a progress bar that fills in each habit's colour
• Habits grouped into Morning, Afternoon, Evening and Anytime
• Swipe to complete or archive, long-press to reorder
• Daily, weekday, weekend or custom schedules
• Count habits like "8 glasses of water" with a goal per day

PROGRESS THAT MOTIVATES
• Perfect days — every habit done — with your current and best run
• Trends for the week, month, six months and year
• Clear comparisons with the previous period, in plain language
• Current and best streak, completion rate and full calendar history
• Collect awards at 7, 30, 50, 100 and 365-day streaks

EVERYWHERE YOU ARE
• Interactive home screen widgets — tick habits off without opening the app
• Lock screen widgets
• Reminders with a "Mark as Done" button right in the notification
• Siri and Shortcuts: "Log Read in Checkstack"
• Spotlight search
• iCloud sync across your iPhone and iPad

MADE YOUR WAY
• Pick an icon and colour for every habit, with icons suggested from the name
• Light, dark or system appearance, and your choice of week start
• Haptics you can turn off

PRIVATE BY DESIGN
Your habits live on your devices and in your own iCloud account. No accounts, no ads, no analytics, no tracking.
