How do I remove the ads ?
Night Clock does not show any advertisements, neither in the free version nor in the paid versions. If you observe any ads check the other apps on your device. I don’t want to contribute to a world which is full of ads in all possible situations of life.
User Interface
How can I change the clock size ?
Using a two-finger pinch gesture you can freely resize the clock layout.
How can I change the position of the clock ?
With a long press on the clock a frame is displayed and the clock can be freely positioned on the screen. The position is automatically saved as soon as the clock is released.
The clock automatically changes its position
The app offers two different options for screen protection:
- move the clock around
- fade the clock If an automatic change of position of the clock is not desired, the screen protection mode can be changed or disabled in the options.
The interface is locked
If Night Clock shows a padlock symbol in the top left corner instead of the menu icon (aka burger icon) the user interface is locked. In order to unlock simply long press the lock icon. Vice versa the user interface is locked by long pressing the menu icon.
If the standby mode is enabled, the user interface always starts in locked mode.
AM/PM indicator not working properly
The seven segment font is not able to draw uppercase letters very precisely. An alternative font is a 14 segments digital font as found at https://www.keshikan.net/fonts-e.html.
Custom fonts
You can choose plain .ttf and .otf files, but also .zip archives which may contain multiple font files. Just navigate to your download folder and choose a file you downloaded before. There are sources of free fonts in the web, such as fonts.google.com and Font Squirrel.
The landscape orientation does not work
Starting from Android 5 Daydreams have a bug. The screen orientation changes to portrait as soon as the screen lock is activated.
- Solution 1: Disable Daydreams completely (System Settings > Display > Daydream). Instead you can setup the auto start feature of the app to your needs.
- Solution 2: Try to enable Settings > Appearance > Force auto rotation in DayDream.

Weather status line
Shows the current temperature and optionally the wind direction and wind speed. The weather data is updated approximately once an hour if the app is in the foreground.
Weather preferences
Allows to configure what is shown in the status line. If you leave the weather location blank the app needs the permission to read your current (coarse) location.
The default weather provider is OpenWeather. The weather provider Dark Sky will shut down its service end of 2021.
Location search dialog
You can search for a location yourself. In this case you can revoke the permission for location access safely.
5-day weather forecast
The headline shows the current location which is especially useful if it was detected automatically.
The following information shown
- temperature (apparent temperature)
- wind direction and wind speed
- cloud coverage in %
- humidity in %
- 3 hour rain volume in mm (only if rain is expected)
Weather data is not shown
Weather data may not be shown for several reasons.
- These are not displayed if outdated for more than 8 hours (e.g. in flight mode).
- The current location cannot be retrieved:
- Can you retrieve weather information, when defining the location manually ?
- Please grant permissions for accessing the location (Android 6+)
- Please check if your location services are activated (e.g. battery saving or high accuracy)
- The network may not be connected. Check your network connection.
Web Radio
How to play a radio stream
The web radio panel appears by tapping the radio icon from the sidebar.
Tab the “+” button to add a new radio station to the panel. You can search for radio stations or enter a url you know. This can be a plain mp3 stream url but also m3u/pls playlists.
Stop playing a radio station by pressing its button again.
How to remove or edit a radio station button
Just tap on a radio station button a bit longer (“long press”) to open the radio streams configuration window. There you can alter the radio stream for that button or remove it.
Alarms
Why does activating Wi-Fi for the radio alarm not work?
Unfortunately, newer versions of Android prohibit automatically activating Wi-Fi when the device is in airplane mode. If you want to use the internet radio as an alarm clock, the only option is to do without airplane mode. Instead, you could manually deactivate Bluetooth, Wi-Fi and data connections.
I woke up before the alarm and don’t want to be woken up today.
A notification is displayed about an hour before the actual alarm time. To deactivate a repeating alarm once, you can select SKIP in this notification. This will skip the next alarm time and the alarm will remain active for the next alarm day.
How do I stop or snooze an alarm ?
An alarm is stopped by tapping the lower right corner. Snooze is enabled by tapping anywhere else. The snooze time is adjustable in preferences > alarms.
Upcoming alarms can be stopped from the notification area. The notification is shown approximately one hour before the alarm time.
Custom mp3 as alarm tone
In the dialog for setting the alarm tone you can choose your custom MP3 file, at the bottom of the dialog. Just navigate to your music folder and select the file you like. With the next release this dialog will move to the alarm overview allowing you to set different alarm tones per alarm.
Autostart
There are two options for autostart: Autostart and Always On
Autostart
The autostart becomes active when the device is connected to a previously defined power source (charger, USB, wireless, charger or dock). If the night clock is interrupted, it restarts as soon as the device goes into standby mode, e.g. when the screen turns off. The period in which the autostart is active can be defined. If all conditions are met at the start time, the night clock is then started. At the end of the period, the app is closed accordingly if the corresponding option is activated (Automatic shutdown > at the end of the autostart period).
Always On
Always on supplements the autostart in the event that no power source is connected. The app is then started when the device goes into standby. A period can be defined in which the function is active. Below an adjustable battery charge level, the function is switched off so as not to discharge the battery too quickly. If the “screen up” function is activated, the device must be lying on a table for the “Always On” function to be activated. I also recommend using the Automatically exit > After timeout (in battery mode) function, because an activated display drains the battery quickly.
Night mode
Night Clock has two modes of operation: day mode and night mode.
The night mode has the following features:
- You can set different colors.
- There is no automatic brightness control. The display brightness is set to a fixed value, even if the automatic brightness feature is enabled.
- The display may be switched off. The display is switched back on if the luminosity exceeds a predefined value (default: 20 lux). If the ambient noise detection is activated, then noise will also re-activate the screen. Noise may also slightly increase the brightness of the display in both of the modes.
- The night mode can be activated automatically as soon as it gets dark (and silent if ambient noise detection is active). Other modes of activation are scheduled and manual. These are meant for devices which do not have a light sensor. If you want to benefit from the automatic brightness control you should leave the night mode activation settings at automatic.
Brightness settings
Manual brightness mode
Sliding along the upper rim of the display you can tune its brightness. The app remembers the current brightness value in night mode which is different from the setting in day mode. Thus, when the mode changes the brightness may increase/ decrease.
While operating on battery the brightness may never be larger than the maximum brightness value defined at Preferences > Appearance > Maximum screen brightness on battery
Automatic brightness mode
In the automatic brightness mode the device sets the display brightness depending on the luminosity. The brightness is automatically set within the pre-defined bounds of the minimum brightness and the maximum brightness. If the device is on battery another value of the maximum brightness is used. The maximum brightness on battery should be reduced as much as possible as the display consumes most of the energy.
Changes in the ambient light conditions should take effect after approximately 20s.
The brightness offset helps to adjust the automatic brightness control to your personal needs. The type of the display, eg. LCD or AMOLED, and the colors shown on the display, have a strong influence on how the display looks like. With the offset you can tune the brightness to be lower or brighter than the default value 0. Because in low light conditions another offset is needed than in a bright environment, the offset can be tuned from the main view by sliding your finger along the upper rim of your display.
In low light conditions the automatic brightness control may not be very accurate. This is due to the fact that most of the devices do not report accurate values below 10 lux.
Widget
The clock widget is not updated
The clock widget needs to be updated once per minute. Due to restrictions of the Android system this is a difficult task. In order to ensure that the update works a foreground service is needed. The same service is managing the autostart of the app. It is indicated by showing a permanent notification in the notification area. If this service is not properly running (or interrupted by the android system) the widget is no longer updated. If you want to (re-) enable this service you can disable and re-enable the autostart of the app. This triggers the start of the service.

Slideshow
Which pictures are shown in the slideshow
The app shows all images in JPG and PNG format. Videos or images in any other format are not displayed. It is currently not possible to select individual images for the slideshow.
How can I select images
For Android Lollipop (version 5.0) and above a folder can be selected for displaying images. It is currently not possible to select individual images for the slide show. It is recommended to create your own folder and copy the images you like for the slide show into this folder. For Android Versions below Lollipop the device’s photo directory is selected automatically.
The slide show appears with a delay at app startup
The loading of the individual images takes place in the background to ensure smooth operation of the app. On older devices or large images it may take some time before the image is ready to be displayed. In this case please try to reduce the size of the problematic image.
How can cloud storage be accessed?
It is currently not possible access to any cloud storage.
Only a black screen is displayed
Please check if there are pictures in JPG format on the device. The option * Hide the background image in night mode * may be activated. If so, a black background is shown instead of a slideshow during the night.
EXIF information is not displayed
Please check whether EXIF information is included in the displayed JPG image. To determine the location from the EXIF information the Google Play Services are required. Some Android distributions may not have these preinstalled.
Speak the current time
The current time is not read out
The app requires an installed text-to-speech engine (TTS) to read the current time. Please check in the device settings whether this is installed and activated on your device.
How can the language be changed?
The selected language depends on the language of your device and cannot be changed within the app.
Notifications
What is the media control?
The media control makes it possible to take control of external music players which are controlled through the notification center.
How do I activate the media control?
The media control notifications can be activated in the app preferences in the notifications section. If a compatible app is running in the background (e.g. Google Play Music, Spotify, Amazon Music, Pulsar, MyBob etc.) the media control is displayed below the clock.
The media control is not displayed
There are some apps that do not use the standard Android interfaces for music control. These apps cannot be viewed and controlled via the media controls.
