JMP SIM Manager is a fully free and open-source companion app for the JMP eSIM Adapter. The JMP eSIM Adapter is a removable eSIM chip that enables any device, not just those with included eSIM chips, to make use of downloadable eSIMs. JMP SIM Manager provides management features such as adding, deleting, enabling, and disabling eSIM profiles for the adapter, and is the easiest option to manage your eSIM Adapter on compatible Android host devices. The manager app is not required once a profile has been downloaded and enabled on the adapter. In other words, you can use a compatible Android device to download your eSIM profile of choice onto the adapter, and then insert the adapter into any device -- Wi-Fi hotspots, dumb phones, laptops -- and the adapter will simply appear as a regular SIM card to those devices. This app also includes a quick compatibility check to determine whether your Android device can be used to manage a JMP eSIM Adapter. Although the eSIM Adapter will work with almost any device once an eSIM profile is loaded, management requires some specific features that may not be present on a small percentage of Android devices. However, even if your Android device is deemed incompatible, you can still manage the adapter from another Android device, using a PC/SC reader on a PC, or, as a final fallback, through the SIM Toolkit menu along with a self-hostable remote server to handle TLS termination.

The KUKSA Companion App demonstrates the capabilities of the Android SDK to connect to a vehicle with an integrated KUKSA Databroker, read data and interact with the actuators of the vehicle. The KUKSA framework is based on the COVESA Vehicle Signal Specification (VSS). The VSS defines the names and semantics of a large set of data entries that represent the current and/or intended state of a vehicle's sensors and actuators organized in a tree-like structure. For example, the vehicle's current speed is represented by the Vehicle.Speed entry. However, VSS does not define how these signals are to be collected and managed within a vehicle, nor does it prescribe how other components in the vehicle can read or write signal values from and to the tree. The KUKSA Databroker is a resource efficient implementation of the VSS signal tree and is intended to be run within a vehicle on a microprocessor based platform. It allows applications in the vehicle to interact with the vehicle's sensors and actuators using a uniform, high level gRPC API for querying signals, updating current and target values of sensors and actuators and getting notified about changes to signals of interest. Showcases covered by the Companion App are: - Door Control - Temperature Control - Light Control - Tire Pressure Check Find out more about KUKSA: - Vehicle Signal Specification: https://covesa.github.io/vehicle_signal_specification/ - KUKSA Databroker: https://github.com/eclipse/kuksa.val/ - KUKSA Android SDK: https://github.com/eclipse-kuksa/kuksa-android-sdk/ - KUKSA Companion App: https://github.com/eclipse-kuksa/kuksa-android-companion/

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. - 100% Device-based, no cloud services or accounts required - Free with no ads or trackers - Open Source (https://github.com/keepalivedev/KeepAlive) - Minimal Battery Usage - Multiple SMS Recipients - Custom Alert Message - Optional: Include Location Information in SMS - Optional: Place a phone call with speakerphone enabled - Optional: Send an HTTP request to a custom URL 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. 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. This data is not shared with the developers or any 3rd parties. The only data transmitted is to the configured emergency contacts. This app does not request network or storage access and no data is sent to the developers or any 3rd parties.

Keep it up checks network services periodically by sending a ping, connecting to a specific port or downloading a site. It can also be used to ensure a connection with a timeout will be kept alive. Features - Create multiple separate network tasks - One task monitors one network service at a specified interval - A task sends a specified number of pings, performs a specified number of connections attempts or downloads a file or a site - Successful and unsuccessful attempts are logged - Downloaded files can automatically be deleted after a successful download or be kept - Notifications can be sent on failure or when a network service goes down or up - A network task can be restricted to WiFi connections, i.e. it does not perform any action on mobile networks with potentially limited download data - The configuration can be exported and imported as a JSON data file - Intervals can be defined during which all background work is suspended for battery saving Permissions - RECEIVE_BOOT_COMPLETED for restarting running networks tasks on device boot - ACCESS_NETWORK_STATE for checking network accessibility - INTERNET for accessing the internet - WAKE_LOCK to keep the device awake while executing a task - FOREGROUND_SERVICE to start the foreground service for running tasks - FOREGROUND_SERVICE_DATA_SYNC to use the foreground service with data transmission - USE_EXACT_ALARM to start networks tasks after expiry of intervals (Android 13+) - SCHEDULE_EXACT_ALARM to start networks tasks after expiry of intervals (Android 11 and 12) - POST_NOTIFICATIONS for sending notifications Note The app uses exact alarms to trigger network task execution. Power consumption during waiting is as high as for a calendar app waiting for reminders to trigger. During execution the power consumption is higher, of course, and short execution intervals cause more overall battery drain. The app works best if you disable battery optimization. If battery optimization is active, network tasks execution may be unreliable especially for short intervals, i.e. they may trigger less often and the trigger time may not be exact. There is a link in the app leading to the Android battery settings for the app. Of course, with disabled battery optimization power consumption may be higher. For Android 15+, it is no longer possible (and no longer necessary) to directly disable battery optimization. Android 15+ provides a setting to allow background activity for an app, which is enabled by default. It is strongly recommended to leave it enabled. The app should work without it, but it can lead to unreliable behaviour.
