Get in touch
For setup help, check-in questions, purchase or restore issues, or suggestions, email wrq142857@gmail.com. You can write in English or Chinese.
For a technical issue, include your iPhone model, iOS version, app version, what you expected, and what happened. A screenshot can help; leave out personal information you do not want to share.
How do automatic check-ins work?
Create a task, select the app that should count toward it, and set your daily deadline, repeat rule, and usage threshold. Automatic check-ins need Apple Screen Time / Family Controls authorization.
When the selected app reaches the configured daily usage threshold, the task can be marked as completed. This reflects usage time, not completion of a lesson, book, or other activity inside that app. You can also check in manually from the task dashboard when needed.
If a check-in is missing, check the authorization, the app selected for that task, and the task rules. Contact us if you need help with the result.
I need help with permissions or reminders
Notification permission allows deadline reminders. Screen Time / Family Controls authorization allows usage-threshold monitoring. These permissions have different purposes: enabling notifications alone does not enable automatic check-ins.
Check the permission you need and the task’s reminder settings. If setup is unclear or reminders are not working as expected, email us with the relevant settings and what happened.
Where can I see my progress?
The task dashboard shows today’s task states and supports filtering and manual check-ins. The calendar shows completed, pending, and missed days, along with daily details and notes. Home Screen widgets show today’s habit status.
For a calendar or widget issue, tell us which task and date are affected, and include the status shown in the app and widget.
What does Premium unlock?
Premium unlocks unlimited tasks, full history beyond the free window, and custom reminder lead times. The app includes purchase and restore flows through Apple’s App Store services. The in-app purchase screen shows the available options, price, and terms.
If a purchase or restoration does not unlock the expected features, contact us with the app version and any error message. Do not send payment-card details or your Apple Account password.
