FindMeSAR is a 'no cost' public service browser app from MappingSupport.com. It is intended for use on smartphones and tablets. Yes, it will run in the browser on a desktop or laptop computer but the location results are unpredictable.
There is also a related web page with more documentation. Many questions will be answered by the information on that page.
FindMeSAR can help emergency responders find you. "SAR" means Search And Rescue. The goal of FindMeSAR is to help make for less search and more rescue.
When you call for help with your cell phone, the person at the other end of the call needs to know your location. The FindMeSAR browser app will display:
1. Your coordinates
2. An accuracy value
3. Elevation if you are in the USA and online
4. A timestamp
FindMeSAR gets your location from your browser. All mainstream browsers offer an interface that can obtain coordinates from the phone's GPS chip. Most GPS chips in cell phones use assisted GPS (A-GPS) in order to speed up the time to first fix. The user's phone might also use data from cell towers, wi-fi hotspots, bluetooth and other location aware technologies in determining the user's coordinates.
Different emergency responders use different coordinate formats. FindMeSAR uses color-coded screens so you can provide your coordinates in the format used by first responders in your area. All coordinate formats use the WGS84 datum.
Blue = U.S. National Grid (USNG). Same as MGRS.
Green = UTM
Yellow = Decimal degrees <== This format is used by 911 call centers
Red = Degrees and decimal minutes
The accuracy value is just as important as the coordinates! If FindMeSAR has been running for at least one minute and the accuracy value is not 30 meters or less then something is wrong. Here are some things to try:
1. If you have an Android phone, open your settings and go to the screen where you turn location services on/off. Make sure the location method (or mode) is set to "GPS Only" (or Device Only).
2. If you are inside a building try to go outside or next to a window so your phone can get better data from the GPS satellites.
3. If you are in a vehicle try to put your phone under the windshield so your phone can get better data from the GPS satellites.
4. If you hold your phone so your hand covers the GPS antenna then your phone will not get any data from the GPS satellites. Hold your phone in portrait orientation with nothing blocking the upper half of the phone.
5. Remember, if you are using a desktop or laptop computer then results are unpredictable. FindMeSAR is intended for cell phones and tablets.
If you are in the USA and your device is online then a few seconds after you tap "Stop", your elevation will be displayed.
FindMeSAR will not work if its files on your phone get corrupted. Here is how to reload the app’s files to your phone so it works again.
1. Delete the app.
2. Browse to findmesar.com.
3. Wait for the app to open.
4. Reload the app.
If the above steps do not fix the problem then open the more documentation page and tap the button "FindMeSAR Known Issues". Scroll down a bit and read the section "If FindMeSAR opens but never seems to work right...."
This link will start Gmap4 which is an enhanced Google map viewer. The most recent location reported by FindMeSAR is used to put a marker and a green circle on the map. The radius of the circle is the accuracy value. If you are outside and your phone has a reasonably good view of the sky, then there should be a 95% chance that your true location is inside that circle.
If you are in the USA or Canada then you can display a high resolution topographic map. Tap the basemap button (next to the Menu button) and select "t4 CalTopo Hi-res". In other countries the basemap that begins "t8" is often a good choice. If you are lost, perhaps this map will help you self-rescue.
The map also shows a small red circle with a crosshair. This symbol will always be positioned at the coordinates produced by your phone or tablet. If you move, this symbol will follow you. Even if you remain in one place it is normal for this symbol to move around on the screen a bit. Tap that symbol to see useful information.
The best way to start the app is with a bookmark in your browser since you will automatically get any new version. If you have an iPhone and start FindMeSAR by tapping its icon on your homescreen, then due to a bug in iOS you do *not* automatically get any new version. Tapping "Reload" after the app opens will fix this problem by installing any new version of the app.

FindMePro is another 'no cost' public service from MappingSupport. This browser app is a research tool that anyone can use to see how different settings on their phone affect the location accuracy of the GPS coordinates produced by their phone. In particular, Android users can compare the three locations modes offered by their phones.
By using FindMeSAR you agree that you are doing so entirely at your own risk. You further agree that you will not make any kind of claim or file any lawsuit against the developer of this software.
The FindMeSAR web app does not retain your location data and does not share your location data with anyone.
