RoadEagle retrieves traffic information from various open data portals (most of them made available by road operators), displays the data in a list and makes it available to TraFF-aware applications, such as Navit. Currently Poland and Lithuania are supported. A data connection is required. The actual data reported may vary between countries. Also, as RoadEagle needs to convert the data from different formats to TraFF, it may not be able to represent all traffic messages as intended by their creators. This app receives requests from compatible apps (consumers) which may expose the device location (and, possibly, where you intend to travel). Because of the location information, consumer apps may refuse to send such requests to apps without location permission. This is the only thing RoadEagle uses this permission for; it will never request a location update. Photo by Joanna Pędzich-Opioła | CC_BY 2.0

Simple application to count the passing vehicules in the street. It can be used for bike advocacy campaign (for example, to report number of bikes passing on a given street).

Use your phones sensors (barometer and compass) to show your current orientation, height and air pressure. Important: * Showing height and air pressure only works, if your phone has a built-in barometer (if this is not the case it provides you a simple compass with orientation in degree). * Calculated height is based on standard atmosphere and can be corrected within the app, if you know your real height.

SCEE is a modified version of StreetComplete, aimed at experienced OSM users unhappy about the lack of advanced editing capabilities in normal StreetComplete. Please be aware that SCEE is not suitable for people used to discard warning messages without reading! Users new to OpenStreetMap are best advised to use StreetComplete: https://f-droid.org/en/packages/de.westnordost.streetcomplete/ Functionality added in SCEE is considerably less tested than what you might be used from StreetComplete, so bugs or unexpected behavior may happen. If you encounter any, please report the issue. Extra features may cause SCEE to behave in highly modified way compared to StreetComplete. For a full list of differences to StreetComplete see https://github.com/Helium314/SCEE#differences-to-streetcomplete F-Droid anti-feature: non-free network, SCEE uses background map tiles provided by jawg, and optionally aerial / satellite imagery by Esri.

SMS my GPS listens for incoming SMS text/data messages and conditionally sends an automatic reply containing GPS location data. The „trigger-word“ and white-listed sender phone number can be configured in the app.

SatDump will allow you to decode a wide range of satellites, exactly as it would on your computer. With a compatible SDR device and necessary hardware, most Android devices will be able to receive and process NOAA APT & DSB, LRPT and even HRPT and most S-Band satellites! This includes many weather, science, and other generic missions. If you also happen to be in range of a geostationnary satellite such as GOES, GK-2A or similar you will also be able to do all processing directly on your Android device. Especially on a phone, a good usecase is receiving 137Mhz weather satellites on the go. Supported SDRs : - RTL-SDR - Airspy - Airspy HF - MiriSDR - LimeSDR Mini

A diagnostic tool that displays data reported by sensors in the phone. GPS and other location providers: * Refresh AGPS data (if supported by phone) either manually, or when a new data connection is detected * Status notification whenever an app accesses GPS (configurable) * Location, speed, bearing and error * Satellites in view and satellites used * Signal-to-noise ration (SNR) for each satellite * Time to first fix and time of last fix * Map view for comparison of different location providers Sensors (as supported by your phone): * Accelerometer (acceleration and gravity) * Rotation * Magnetic field * Orientation (azimuth, pitch and roll) * Ambient temperature * Pressure * Relative humidity * Ambient light * Proximity Networks: * GSM/CDMA/LTE cells in range with network type and signal strength * WiFi networks in range, with encryption type, channel and signal strength Known limitations: * Some phones will report only the network cell with which they are currently registered. On such phones you will only see one cell under "GSM" or "CDMA". This is a limitation of the phone's radio firmware, and SatStat has no way of getting more information from the device. * Some devices ignore the command to refresh AGPS data. This is a limitation of the GPS driver (which varies from device to device and is usually proprietary). Starting with version 2.0, SatStat has a workaround in place for automatic AGPS updates.

Some applications do not allow you to quickly and conveniently save files to a specified path. As a result, you have to install and use third-party file managers. Just share a file from any app to "Save to..." and Android will ask you where you want to save it. Or use the automatic saving option, then the files will be immediately stacked in the directories specified in advance.

It stores GPS coordinates and sends them to your Web server so you can see where is the device. * You can build your own server (more privacy). * Send coordinates by Telegram (Bot) and SMS. * Settings from the website. * Control over time of activity and downtime to save battery. * Easy to create accounts without requesting personal data. * Timer for emergency. It's just a project, so it can only be used for experimental purposes and not for security purposes.

Note: You must also install Location Map Viewer to display the results. This app adds the option Show Articles in Map to any app that can shown/send/share a geo location or geo-uri . This app hooks into the android system to intercept "view geo-uri". When getting a geo-uri it asks encyclopedia wikipedia (or travelguide wikivoyage or knowledgebase wikidata or photogallery wikimedia) and shows the results in Location Map Viewer (or in any other installed app that understands the format 'kmz'). Location Map Viewer shows a map with bubbles (or article-icons if enabled/available) for every wikipedia article found. If you click on a bubble you get a popup with a short article description and a button that links to the full article. Here are some f-droid apps that are compatible with Show Articles in Map navigation: OsmAnd, public transportation: Transportr or oeffi translate postal address to geo Acastus Photon Share your current position LocationShare or My Position Required Android Permissions: INTERNET: to download article data from wikipedia or wikivoyage Server .

Augmented reality application which overlays the names of hills and mountains on a camera view. The supplied data for hills of the UK and Ireland is better than that for the rest of the world. N.B Although it is not necessary (since v0.30) to have Google Maps installed to install the app, attempting to view the map overlay mode if you don't have Google maps installed, will crash the app. Even if you have that installed the "birds eye", map overlay mode won't work because the only map source is Google Maps and there isn't an API key in the source code. Anti-feature: Tracking. Crash reports are sent without interaction, but that can be disabled in the settings. Google Analytics was removed before building.

SmsLoc is an application that queries the location of contacts without the use of mobile data. It uses GPS to retrieve current position and SMS for requests/responses. SMS request format: `Loc?` SMS response format: `Loc:LAT,LON,ASL,UTC_S,V_KMH,ACC_M,BAT_PCT`, where: - `LAT, LON` are latitude and longitude in degrees rounded up to 4 decimal places.[^1] - `ASL` or Above Sea Level is the absolute altitude as reported by the GPS in meters - `UTC_S` is the timestamp of the GPS fix in seconds. The timestamp corresponds to the time of the actual fix, and not when SMS was received. - `V_KMH` is the speed in kilometers/hour - `ACC_M` is the accuracy reported by the GPS chip in meters - `BAT_PCT` is the battery percentage of the device sending the response
