Keep Alive

Keep Alive will send a custom message via SMS to one or more people if you haven't used your device in a given period of time. Intended to be used as a failsafe for those living alone in case of an accident or other emergency. Once the settings are configured, no further interaction is required.

Available Translations: French (CA), German (DE), Polish (PL), Russian (RU)<br/> Supports Android 5.1 (API 22) and up

How it Works

Keep Alive uses your device's lock screen, or the usage of specific app(s), to detect activity. If your device hasn't been locked or unlocked within a set period of time, 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. If enabled, a second SMS will be sent with location information to aid others in locating you.

Main Settings

Monitoring Method
- Device Lock/Unlock: Use the lock screen to detect device usage (recommended)
- App Monitoring: Select one or more apps that will be used to detect device usage
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
- May be delayed up to an hour by the OS if the device has low power or is in DnD mode
- Default is 12 hours
Minutes to Wait
- If the 'Are you there?' prompt is not acknowledged within this time, an Alert will be sent
- Will not be delayed
- Default is 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

Permissions

Keep Alive requires the following permissions to operate properly:

Usage Stats: Used to determine when your phone was last used by checking for lock and unlock events
Schedule Exact Alarms: Needed to ensure that we can set alarms that go off even when the device is idle or in Do-Not-Disturb mode
Send SMS: Used to send SMS messages to your emergency contact(s)
Send Notifications: Used to display the 'Are you there?' and 'Alert triggered' notifications

Optional Permissions

If Include Location is enabled:

Precise Location: Necessary so that we have the most accurate location information to share with your emergency contacts
Background Location: Necessary to be able to get location information when the device is idle

If a Phone Call number is configured:

Make and Manage Calls: Basic permission to make phone calls
Manage Overlays: Necessary to be able to make phone calls when the device is idle

App Restrictions / App Hibernation

Android now automatically removes permissions for apps that have not been used recently. Keep Alive, once the settings are configured, does not need any further interaction and may have its permissions revoked, possibly preventing it from sending an Alert. Keep Alive was designed to operate as unobtrusively as possible and, as an alternative to bugging the user to open the app periodically, expects this behavior to be disabled. On the most recent version of Android this is called 'Pause app activity if unused' and can be found on the App Info screen for Keep Alive.

Why?

Keep Alive was created after separate incidents with colleagues who lived alone and lost consciousness at home. One was found within 24 hours by a concerned friend doing a welfare check and was saved, albeit not unscathed. The other was not discovered for more than 36 hours and sadly succumbed to his injuries after several days in the ICU. If they had been found even a few hours sooner, things may have turned out differently. I am hoping that this app can help prevent similar tragedies in the future.
