In the Hobonichi Techo app, by linking with the device's default calendar, you can automatically record schedules registered in your calendar to your timeline. 

If the schedule is not displayed, please check the following in order to see if any apply.

Calendar is not connected / settings are incomplete 

If schedules for the current day and the past are not displayed, please check the settings with the following steps first. 
*If you reinstall the app, settings will be reset and the connection will be released.

1. Tap [Menu] at the bottom right of the app.
2. Tap [Settings & Payment Information].
3. Tap [Data Acquisition].
4. Check if the [Calendar] section is set to "Connected" or "Not Connected".
   • If [Not Connected]
     Tapping "Not Connected" will open the device settings screen, so please allow "Full Access" for the calendar. 
     *When connected for the first time, schedules from the current day and the past (up to 50 days before the start date) will be synced. 
     *If you reconnect after disconnecting once, schedules during the disconnected period will not be synced.
   • If [Connected]
     Tapping "Connected" will open the calendar detailed settings screen, so please check if the schedule items you want to display are checked. 
     *If you change the settings, the changes will be reflected in schedules synced thereafter.

Initial calendar sync is in progress 

When linking with the calendar for the first time in the "Hobonichi Techo app", schedules are synced from 50 days prior to your start date. During this initial sync, the text "Loading..." and a Senpai illustration are displayed at the top right of the app screen. If you tap the Senpai illustration, the sync progress will be displayed, so please wait until the calendar sync is finished.

Schedule is not registered in the device calendar 

If all or part of the schedules for the current day and the past are not displayed despite there being no problem with the above connection, please check if the corresponding schedule is registered in the Device's Default Calendar.

*The Device's Default Calendar is the "Calendar" app for iPhone. For Android, "Google Calendar" is often the default calendar, but it varies depending on the model.

*If you want to display schedules from another calendar app (such as Google Calendar) instead of the Device's Default Calendar, please refer to this help page.

Not displayed due to sync timing with the device calendar 

The timing when the "Hobonichi Techo app" syncs with the Device's Default Calendar schedule is as follows. Please check if the non-displayed schedule is due to this sync timing.

■ Timing when schedules are synced to the app 

The Hobonichi Techo app syncs the schedule from the Device's Default Calendar to the app at the timing when you first open the app on or after the date of the target schedule (the current day). 
*Schedules for future dates will not be displayed in the app until that day arrives.

Example) A schedule registered in the Device's Default Calendar with the date and time "15/10/2025 12:00-13:00" will be synced when you open the Hobonichi Techo app for the first time after "15/10/2025 0:00". 
For instance, if you do not open the app all day on 01/10/2025 and open it on 15/10/2025, the "15/10/2025 12:00-13:00" schedule will be synced at that timing.

■ About schedules changed in the device calendar 

Once a schedule has been synced from the Device's Default Calendar to the Hobonichi Techo app, even if you change it on the Device's Default Calendar afterwards, that change will not be reflected in the app. 
*You can edit the date, time, and title of the schedule on the app (steps are here).

If the change was made in the Device's Default Calendar before syncing to the Hobonichi Techo app, it will be reflected because it is read with the latest information when syncing to the app.

■ About schedules added to the device calendar 

Schedules newly registered in the Device's Default Calendar will be synced to the app until the end of that day. Schedules registered retroactively to the Device's Default Calendar after the next day has arrived will not be reflected in the app. 
*Schedules registered for future dates will be synced at the timing when the app is opened after that day arrives, as described above.

Example) A schedule registered in the Device's Default Calendar with the date "15/10/2025" between "01/10/2025 0:00 - 23:59" will be synced when you open the app afterwards. 
On the other hand, after "16/10/2025" arrives, a schedule registered in the Device's Default Calendar with the date "15/10/2025" will not be reflected in the app.

If none of the above apply 

If none of the above causes apply, please try the following. 

*Past data that failed to be retrieved due to sync timing will not be re-synced even if the following operations are performed.

Update the app to the latest version 

Please update the app to the latest version from the app store and check if syncing occurs thereafter.

• App Store is here 
• Google Play is here

Restart the app 

Please completely close the app once, then restart it and check if syncing occurs.

Re-login to the app 

Please re-login to the app with the following steps and check if syncing occurs.

1. Open [Menu] -> [Settings & Payment Information] at the bottom right of the app screen.
2. Tap the [Log Out] button at the bottom of the screen to log out.
3. Completely close the app once, then restart it.
4. After restarting, please [Log In] with the same account.
