Sum of Days: Life Tracker2.7 - App Store

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.

PRIVATE BY DESIGN

No Sum of Days account is required. Your tracked values stay on your devices and in your private iCloud storage when sync is enabled. Review, Monthly Rewind, and Year insights are generated on device. Entry notes and days based only on Apple Health imports stay out of Spotlight unless you opt in.

SUM OF DAYS+

Use the core tracker for free. Sum of Days+ unlocks unlimited items, more icons and colors, custom ranges and goals, and app locking with Face ID or Touch ID. Choose monthly, yearly, or lifetime access.

Subscriptions are billed through your Apple Account and renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel subscriptions in App Store account settings.

Record what matters. Review what changed. See the sum of your days.
