About this app

Are you spending more time looking down at your smartphone?

KubiMoni is a posture monitor that uses a sensor to measure your smartphone's "vertical angle" and only notifies you if you continue to hold it with your head down.

It monitors in the background even while you're using other apps, so you can enjoy social media and videos as usual.

■ For those who:
・Find themselves looking down at their smartphone for hours on end
・Are concerned about neck and shoulder strain, and eye fatigue
・Are concerned about straight neck, neck wrinkles, and double chin
・Want to correct their posture but can't seem to notice it themselves

■ Main Features

◇ Constant Tilt Monitoring
Measures your smartphone's vertical angle (how upright the screen is) and warns you if it remains tilted below the set angle for an extended period.
The default setting is "if the vertical angle is less than 40° for 10 seconds." It won't sound if you just glance down for a moment.

◇ Monitors Even While Using Other Apps
Operates in the background while displaying a constant notification. We tend to look down while watching videos or using social media.
This app helps monitor that.

◇ Notification + Vibration Warning
Notifies you with a heads-up notification at the top of the screen and vibration. Warning sound and vibration can be turned on/off individually.

◇ Full-Screen Overlay Warning (Optional, Off by Default)
For those who don't notice notifications, a mode is available that displays a large warning at the top of the screen.
Please grant Android permission only when using this feature.

◇ "15-Minute Pause" and "Stop" from Notifications
When working with your device on a desk, you can pause or stop with a single tap from the resident notification button.

◇ Power-Saving Automatic Sleep Mode
When the screen is off, in your pocket or bag (when the proximity sensor is activated), or face down,
monitoring automatically stops. This prevents unnecessary battery consumption and false alarms.

◇ Real-Time Angle Gauge
When you open the app, you can see the current vertical angle on a semicircular meter. The three-color band ("Good grip / A little too low / Looking down") clearly shows at a glance how far you can tilt your phone before a warning is triggered.

◇ Today's Record and Share
Records the number of downward-tilting warnings and the monitoring time for the day. You can share this with friends along with the percentage of good posture.

◇ Finely Adjustable
Adjust the warning angle (20-60°), warning interval (5/10/20/30 seconds), sound, vibration, and overlay.
Adjust it to suit your habits, whether you prefer a stricter or more lenient approach.

■ How to Use in 3 Steps

1. Open the app and tap "Start Monitoring" (it will ask for notification permission the first time you use it).
2. Then, simply use your smartphone as usual.
3. If you continue to look down, you will be notified and vibrate. Adjust your grip to hold your phone upright.

■ Required Permissions

・Notifications: Used for persistent notifications indicating monitoring is in progress and for issuing downward-tilting warnings.

This notification is essential for apps that run continuously in the background, due to the way Android works.

* Overlay: This is only used when "Fullscreen Overlay Warning" is turned on.

The default is off, and if it remains off, permission will not be requested.

* Exclude from Battery Optimization: When Android's power saving function is activated, monitoring may stop after a while.

This is an optional setting for stable monitoring (the app can be used even without this setting).

* Location information, contacts, camera, microphone, and storage are not accessed in any way.


■ Precautions

* This app is not a medical device. It is not intended for the diagnosis, treatment, or prevention of disease, and
does not guarantee any effects. It is a "habit-forming support" app that helps you become more conscious of your posture.

* If you have symptoms such as pain or numbness in your neck or shoulders, please consult a medical institution.

* Due to the characteristics of the sensor, there may be errors in tilt measurement. Warnings may be more likely to appear in places that are shaking, such as inside a vehicle.

* This is an Android-only app (there is no iOS version).

* Depending on the device or manufacturer's unique power-saving features (such as some Xiaomi/OPPO/HUAWEI devices),

monitoring may be disabled. In that case, please add this app to the "protected apps" on your device.

■ Other

* Free to use (ads will be displayed)
* No account registration required
* Records are stored only on your device

Hold your smartphone at eye level. A long-necked giraffe will watch over your neck today.
