Sum of Days: Life Tracker

Ask about your days with private, verified answers—plus improved filters, new OS 27 portrait widgets, and richer Shortcuts and system actions.

Track what matters. Understand what changed.

Sum of Days is a private life tracker for habits, health, mood, symptoms, personal numbers, notes, and everyday routines. Record in seconds, see your history across days and years, and turn it into a clear review with every finding linked to the days behind it.

A TRACKER THAT GIVES SOMETHING BACK

Review compares the current week, month, or year with the previous period. See meaningful value changes, shifts in how often you recorded, standout days, and items that moved together. The analysis happens on your device, and you can open the exact dates behind each finding. Monthly Rewind turns up to three verified findings into a one-page visual summary of your last 30 days.

TRACK LIFE YOUR WAY

• Record numbers, daily totals, habits, statuses, short text, and longer notes • Create custom items with your own name, icon, color, unit, range, goal, and schedule • Add entries quickly from the app, widgets, Shortcuts, and Spotlight. On iPhone, also use Control Center, the Lock Screen, or the Action button • Set flexible reminders and keep key trackers on your Home Screen with widgets • Connect supported Apple Health data, including steps, weight, height, exercise time, walking and running distance, active energy, stand hours, and sleep

SEE THE SAME HISTORY FOUR WAYS

• Day gives you a focused daily dashboard • Month reveals what happened across the calendar • Timeline lets you scan complete days without hiding the details • Year turns hundreds of entries into a readable life map

UNDERSTAND EACH ITEM

Open Item Lens to see a full year at a glance, then switch between Line, Bar, Calendar, and All-Time views. See totals, averages, latest values, and patterns without losing the records behind them.

MADE FOR THE APPLE ECOSYSTEM

Use Sum of Days on iPhone, iPad, Mac, and Apple Watch. Add and review data wherever it is most convenient, use widgets for quick access, and sync records across devices with your private iCloud storage.
