Requirements
Keep Alive requires that your device has an active cellular plan. WiFi calling and messaging will be used if the device supports it.

How it Works
Keep Alive uses either your device's lock screen or another app(s) to detect activity. If your device hasn't been lock or unlocked for a set period of time, or if you haven't accessed the selected app(s), you will be prompted with an 'Are you there?' notification. If this notification is not acknowledged an Alert will be triggered. Based on the configured Emergency Contact Settings, one or more SMS messages and/or a phone call will be placed to notify others that you may be in need of assistance.

WARNING: If your device restarts, Keep Alive will not be able to check for recent activity until the screen is unlocked. On Android 7.0+, Keep Alive can still send an alert before the screen is unlocked but must assume you have been inactive based on its last saved state. On older Android versions, Keep Alive cannot run at all until the screen is unlocked and alerts will not be sent.

Main Settings
- Monitoring Method - Choose between using the lock screen or another app(s) to detect activity. If using another app(s), you will be prompted to select the app(s) to monitor.
- Hours of Inactivity Before Prompt - how many hours since your phone was last locked or unlocked before you are prompted with an 'Are you there?' notification. Defaults to 12 hours
- Minutes to Wait - if the prompt is not acknowledged within this time, an Alert will be sent based on the configured emergency contact settings. Defaults to 60 minutes
- Rest Period Time Range - a range of time during which inactivity will not be counted. For example, with 'Hours of Inactivity' set at 6 hours and a Rest Period of 22:00 – 6:00, if the device is last used at 18:00, the 'Are you there?' check would not be sent until 8:00. Note that an alert can still be sent during a rest period if the 'Are you there?' check was sent BEFORE the start of a rest period.
- Auto-Restart Monitoring After Alert - If enabled, monitoring will be automatically restarted after an Alert is sent.
- Alert Webhook - Configure an HTTP request to be sent when an Alert is triggered

Emergency Contact Settings
- Phone Call Number (Optional) - when an Alert is triggered a phone call will be placed to this number with speakerphone enabled

One or more SMS recipients can be configured with:
- Phone Number - the phone number to send the Alert SMS to
- Alert Message - the message that will be sent when an Alert is triggered
- Include Location - if enabled, your location will be included in a second SMS

Privacy/Data Collection
No data is collected other than the configured settings and nothing is shared with the developers or any 3rd parties. The only data transmitted is to the configured emergency contacts.

Is Keep Alive Lite free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Keep Alive Lite require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Keep Alive Lite safe to install?
We link to the exact APK published by F-Droid Open Source. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Keep Alive Lite?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
