DuoKit: Fold Tracker

Built for iPhone Duo. Every fold and unfold logged automatically, beautiful charts that reveal your habits, and one wallpaper made for all three screens.

DuoKit is the fold tracker and personalization kit made for iPhone Duo. How many times a day do you unfold your phone? How long do you stay on the big screen, and when? DuoKit turns those answers into clear, beautiful stats.

AUTOMATIC LOGGING — NO NEED TO OPEN THE APP • Add the ready-made shortcuts in one tap, or follow the guide to create “Open or Close” automations • Set it up once and every fold and unfold is logged silently in the background • Log manually from the app, a widget or Control Center any time

PRO-LEVEL STATS • Today at a glance: unfolds, unfolded time, average session and a live state timer • Day, week, month and year views, each compared with the same point in the previous period • Trend charts, 24-hour distribution, time-of-day breakdown, session types and a weekday × hour heatmap • Smart insights: your peak hour, busiest day and longest session • Records and a full timeline with date jump, manual entries and deletion

OPTIMIZED FOR THE INNER DISPLAY • Unfold iPhone Duo and the dashboard switches to two columns — trends on the left, habits on the right

HINGE LIFE • Estimates how much of the hinge’s design life you’ve used and how many years are left • Set your own design rating and cycles from before you installed DuoKit

HOME SCREEN & LOCK SCREEN WIDGETS • Today, 7-day trend, full dashboard, quick logging and hinge life • 19 color themes — and every widget can have its own • Lock Screen widgets and Control Center buttons

TRI-SCREEN WALLPAPER • Pick an image for the cover screen, inner portrait and inner landscape • DuoKit joins them into one wallpaper and shows you how to align it in each pose

SHARE & ACHIEVE • Daily, weekly, monthly and hinge-life report cards in three styles • 24 achievements and global Game Center leaderboards (unfolds shorter than 3 seconds don’t count)

REMINDERS • Unfold-duration reminders, daily count and time limits, and a daily report notification

PRIVATE BY DESIGN • Your data stays on your device and in your own iCloud. DuoKit has no servers and collects no personal data • Automatic iCloud backup, restore, and CSV / JSON export

Available in English, Simplified Chinese, Traditional Chinese, Japanese and Korean.
