Kirutokewyi Support

Here, we are distributing additional information on the watch face app "Kirutokewyi" for Wear OS.

Important Announcement

The support for our watch face app, "Kirutokewyi" will end on January 14, 2026. Please note that after this date, you will no longer be able to download or reinstall the app. This is due to a change in specifications from Wear OS 5.0 onwards, which means that watch face apps other than Watch Face Format will no longer be supported. Until now, this watch face app has been designed based on the concept of providing users with free customization, but Watch Face Format is very restrictive, making it extremely difficult to deliver the concept of this app, so we have decided to abandon providing it. We sincerely thank everyone who has supported and used our app over the years.

Limitations

AM/PM display

For system dependent settings, different system settings on the companion device and smartwatch will result in different preview and actual appearance.

Refine your search

File name narrowing in local content search is supported on Android 10 or later.

Font

The default font is automatically set if an unsupported format or corrupted font file is selected. Support for fonts may differ depending on the OS.

RTL display

This app does not support RTL display. Therefore, depending on the setting language, the layout may not be as intended.

Local Data

This app saves the set image and font data and its file name in the device as a local file of this app. These files serve as cached data, but there is no function for users to explicitly delete them. If you want to completely delete the set data, clear the storage from the system settings.

Saving and initializing settings

Settings that do not affect appearance are intentionally excluded from being saved or initialized. There is also a setting that does not save to a file even if it can be restored to the initial state.

Advanced settings

If the information for vertical writing cannot be obtained from the font, the information for vertical writing is generated from the information for horizontal writing. When using font information, the glyph direction follows the font. For example, full-width tilde may be mirror-inverted depending on whether or not they are set. Only CBDT/CBLC is supported for information for vertical writing in color fonts. Other color fonts use information for horizontal writing. Voiced and semi-voiced sound mark are displayed overlaid on the previous character. For this reason, visibility may decrease. Tate-chu-yoko does not reflect the information for vertical writing included in the font. The monospace feature may differ from the display expected by the font. Some half-width characters may be adjusted for vertical writing. If the weather forecast exceeds the maximum number of lines, the text omitted in vertical writing may be different from horizontal writing.

Extra top and bottom padding

Extra top and bottom padding does not work in vertical writing.

Fahrenheit temperature

The Fahrenheit temperature is calculated by converting the Celsius temperature obtained from the source and then rounding to the nearest whole number.

Palette transparency

Palette transparency overlaps with the transparency by function. Also, tiles are affected by the palette transparency. Please note that the shadow of the text is generated based on the text without outlines.

App Shortcuts

App Shortcuts do not function in ambient display (always-on display). If the mobile and smartwatch cannot establish communication, the mobile side will display an alternative icon.

Weather Forecast Update

The update interval of the weather forecast varies from 1 to 12 hours depending on the region. If the setting to display the weather forecast is not specified, the weather forecast update will not function.

Known issue

The appearance may differ from the settings

We are currently checking the situation. If this happens, we apologize for the inconvenience, but please try switching the recipe once to see if it displays as intended.

Weather forecasts may not be able to search for verified keywords

Android 12 and earlier models use deprecated services. This can cause problems. If this situation occurs, please consider migrating to Android 13 or later, or using alternative search terms 

When the font is changed, the display position shifts depending on the time

In proportional fonts, the size of each character is not uniform, so the display position changes depending on the combination. Due to consideration of the balance between the appearance and visibility of proportional fonts, this app provides only simple measures.

Can't change image

We have confirmed that this situation occurs when the local file is corrupted. If this situation occurs, please try reinstalling this app.
