Support
Start with the checks below. If none of them answers your question, the contact address is at the bottom of this page.
A reminder did not appear, or arrived late
Check that notifications are allowed for KOOCOOLS, that the routine’s reminder is turned on, that the device is not in a focus or do-not-disturb mode, and that the scheduled time has not already passed. On Android, reminders can arrive a few minutes late unless “Alarms & reminders” is allowed for the app in device settings.
Adding a widget and keeping it current
Add the KOOCOOLS widget the way your device adds widgets to the home screen, then choose which widget preset it shows. It redraws when you record something, and on Android also when the date changes. If it still looks out of date, open the app once and confirm the routine has not been archived or deleted.
Making and restoring a backup
In Backup & restore, making a backup writes everything so far to one JSON file and hands it to the share sheet. Restoring asks you to pick a file, checks it inside a separate temporary database, and shows what the file contains before anything changes. A restore replaces the current groups, routines, and records on the device and cannot be undone, so make a fresh backup first if today’s data still matters.
I need to move my data
Export a backup file before you change devices. That file is the guaranteed way to carry earlier records over, and on Android automatic backup is not used, so records cannot be recovered if you remove the app or move to a new device without one. The exported JSON file is readable and should be stored with the same care as your routine records.
Changing the language
KOOCOOLS follows your device language and can also be set to Korean, English, Japanese, Simplified Chinese, or Traditional Chinese in Settings. The change applies immediately. Group, routine, field, and unit names you typed yourself are never translated or overwritten.
I want to remove my data
Delete the relevant routine or remove the app. Remember to separately delete any backup files you saved elsewhere.
Reporting a problem
Include the app version, your operating system and version, the steps that led to what you saw, and the setup of the routine involved — schedule, goal, and reminder. What you expected and what happened instead is usually enough to reproduce it.
Not a medical service
KOOCOOLS records what you enter. It does not diagnose, interpret a health value as good or bad, or give medication guidance. Talk to a qualified professional about medical decisions.
