How to use LockOnMe
LOM enables you to transmit your latest position as well as Points Of Interest (POIs) which others can track in real time (or any time later), to display other people's position and/or POIs, or to locate your own POIs (finding back your parked car, etc.).
Those to whom you communicate your chosen Target ID & Tracking Code will be able to access your latest broadcast position and POIs (be it live - updated at a chosen interval - or not).
Your device has to be able to determine your precise position (using GPS or WiFi), which is paramount to make relative positioning work.
Getting a precise position from your device can be constraining: cell-tower / GSM localisation is not accurate enough, so you will have to lock on a GPS signal (for outdoor use) and/or connect to a WiFi network (especially when indoors).
You can see the status of the Own Position Service (O.P.S.) from the dashboard: it should be ACTIVE:
A countdown is displayed while the device tries to get an accurate position, at the end of which the Info button will be enabled, providing more detailed O.P.S. status information - with guidance on how to resolve a faulty service.
Press on the Transmission button from the dashboard to access the following screen:
There are 2 ways to transmit your position:
- by "broadcasting" your position to the server (TrackCentral); those to whom you gave your tracking details will be able to see your latest broadcast position and POIs, be it in real time or not (your latest broadcast position and POIs will persist)
- by sending an SMS with your fixed position
Press on Start Broadcast, then enter the target details you choose to be associated with (as shown below).
You can have as many Target IDs as you want, and also as many Tracking Codes per Target ID as you want. Each Target ID is unique, protected by the password first associated with it.
The server only stores these tracking details, geographic coordinates and chosen names for the Points Of Interest you may decide to create - nothing else about you or your phone - to ensure anonymity (provided you don't give away your name in your tracking details).
(This is by the way quite rare, in comparison to the other tracking applications.)
Once you are successfully authenticated, LockOnMe will send your geographic coordinates to the server at the selected interval (press on the displayed interval to change it), until you press on Stop Broadcast.
Once you start the position broadcast, you can press the Home button on your device to continue broadcasting in the background with the app no longer visible, apart from its notification in the status bar.
There is also a tickbox to start broadcasting as soon as the application starts.
You would then have to share your tracking details (Target ID & Tracking Code) with whoever you wish to be tracked by. There is a button to send your tracking details from the app, by email or SMS; SMSs containing tracking details can then be imported from the app (see the TRACKING section below).
The Connect Only button enables you to connect to the server without broadcasting your position. It is useful in case you just wish to access your Points Of Interest, without having to give away your position; you can then display them on a map or radar, and add or delete some.
Press on Send fixed position by SMS and select the recipient; after confirming, LockOnMe will send a text message with your most recent geographic coordinates (this requires the device to have determined your precise position at least once since the application started):
See the next section for how to import an SMS with a fixed position from your app.
Accessible by pressing on the Tracking button from the dashboard, this screen will enable you to add the targets whose position and POIs you want to display on a map or radar.
If you are broadcasting your position, this screen will also display any Point Of Interest which is currently associated with your Target ID & Tracking Code (as shown above).
There are 3 different ways to add a target; press on Add Target to open the following menu:
- the first option lets you add a target enabled for live tracking, by entering its tracking details manually.
The target's position will be downloaded from the server every 3 seconds; the position is updated live provided that the target user broadcasts its position at the same time - in any case, its latest known position will be downloaded, as well as the time when it was broadcast.
In addition to its last broadcast position, its recorded Points Of Interest will also be made available.
- the second option enables to add a target for live tracking (same logic as above) by importing a special SMS containing the tracking details.
You would need to have received such an SMS from a target user (who would have shared his/her tracking details by SMS from the app, as mentioned earlier).
After pressing on the option, you will be presented with a list of all the contacts who shared their tracking details with you by SMS from their app; click on the chosen contact to import his/her latest tracking details.
- the third option ("Import fixed position from SMS") enables to import the fixed position of a target from an SMS he/she sent you from LockOnMe, containing his/her geographic coordinates (as seen previously).
Likewise, select among the list of contacts who shared their fixed position with you by SMS, and their latest SMS containing a fixed position will be processed.
A few seconds after entering the Target ID & Tracking Code, information on your target should be displayed (it may not be updated straight away though since it does not auto-refresh at the moment, in which case you would have to close and come back to this screen a few seconds or minutes later if you want to have the information): distance, time elapsed since latest position broadcast and any associated Point Of Interest (press on the target area to expand it and reveal them, if any, such as in the screenshot below).
You can also save and load target lists (lists of Target ID and Tracking Code pairs) by pressing on the relevant buttons.
Tip: this screen lets you choose which target(s) and Point(s) Of Interest to display on the map/radars (all displayed by default).

Press on the Display button from the dashboard to open a map or radar showing the position of your targets, their associated Points Of Interest and/or your own POIs.
There is a button to create a new Point Of Interest and assign it to a Target ID & Tracking Code pair (the ones used for broadcasting your position or "Connect Only", or, if unknown, new ones which you will have to enter). The people tracking you will also see your POIs.
Equally, there is a button to remove a selected POI.
Press on the blue icon in the top-left corner to search for a specific location (via Google Places).
The 2 buttons in the top right-hand corner are respectively used to select the layer and to bring the user's location into focus.
The range is automatically determined according to your distance to the farthest target; you can override the range by pressing on the corresponding text fields (you will be prompted to select the required range among a pre-defined list).
On-screen, the range is represented by the radius of the largest circle.
Motion Tracker (inspired by the movie Aliens...):
Likewise, you can override the default range (which is this time determined by your distance to the closest target), by pressing on the corresponding text fields on the right.
Tip: you may not want to display certain targets or Points Of Interest on this screen: go to the Tracking screen and untick "visible on maps" for each unnecessary element (target or POI).
+ Web interface:
There is a web interface that non-app users can access in order to display targets on maps: lockonmeapp.com/map. So people don't have to use the app to pinpoint your (real-time or last broadcast) location.
From that web interface, it is also possible to connect to a target and edit its Points Of Interest (the password will be needed in addition to the tracking details pair ID/TC).
Several map layers are available.
