The newest versions has provided improvenets of performance, location precision, and user friendliness of the phone application. With ongoing program fixes and improvements, it is certainly worth the investment. Yeah my bf and I have this app and his locations are constantly hugely off, like in another state off… then back, then off again.
TiSPY allows you to instantly track their phone location. Location feature b. using device internet (accurate about Meter, need internet availability) c. using. A free web site allows users to track the location of any cell phone? cell phone number or anyone that you want to track be sure and include the area code!.
I wish I knew! Also I have noticed my map is almost always incredibly accurate! Like to the parking spot. Am I being naive or is this to be expected?? You gave me 5 digit code and there is only room for 4 on screen. How does that help a parent? Top Spying Apps for Android and iPhone. What exactly is Geozilla? If a family member ever finds himself in emergency situations, they can notify all family members on the account immediately. The speed in which every member of network is contacted is remarkable.
Geozilla app allows tracking members who are active on social media. The programm alerts parents when something is amiss. Through the use of geo-tracking and satellites, parents can know exactly where someone is. This information is displayed in real-time on a map. Parents always know where their kids are.
Phone spy application does not drain the battery on device that is being targeted. This ensures that phone will always be on and not drained so they can be tracked with ease. It allows parents to check on children quickly. For instance, to do-list allows all family members to know what parents need to be accomplished. These errands can be shared with other members. You can control cell phone from a distance. You know how much battery life remains on device as well. There will be an option to "Save map to use offline" at the bottom.

Yes, unless you haven't updated Maps there were a few releases where saving offline maps wasn't supported at all. But I wouldn't call this "pretty easy", I'd call it "cumbersome and obscure".
This app is not completely free. The clean User interface makes it better than other mobile tracking apps. If your number is ported then, this is not for you. A few years late, but that is completely wrong. So all in all, i think the people doing that aren't that clueless about tech, you are. Trigger profile , 9 Sep 9: The user interface of this app is very clean and attractive.
Usually the phones fine tune the location using tower signals as well and sometimes even wifi by comparing ssids in the area with online databases yay Google street. That feature that allow you to save the map data from certain places is useful indeed. I was using Osmand for offline navigation outside mobile coverage or where you only get crappy 2G.
I dont know if this article is acurate I have always assumed when they talked about locating a cell phone it was triangulated. Im sure there are time out in the country where the phone cant sync the timeing signals from the three closest towers but for most metropolitan areas I would say trigulation by cell phone is very accurate. John Fenderson profile , 10 Sep 8: Even the law doesn't require anything like great accuracy. Pete Wilson , 29 May 3: A few years late, but that is completely wrong.
AGPS is full blown satellite GPS, but with location and especially startup assisted by cell tower location information, as full blown GPS startup can take over 30 seconds when the GPS has no idea where on earth you may be. John Fenderson profile , 9 Sep 9: Tower triangulation is never precise, but the more towers that can see the phone, the more accurate it is. By the way, those requirements are: People however do confuse GPS and Tower triangulation - they are two separate things, both of which can locate where a device is being used.
As far as the triangulation goes, if someone is in a location where they can reach multiple towers both of their own carrier or others you can get it down to about a 6ft diameter area of where a person is using the tower data alone. Identifying your location with GPS or Cell tech uses the same principle. How long does it take a signal to reach you? Since we know how fast the signal travels we can calculate how far you are from the signal origin giving us a radius. A single signal source means you can be anywhere on the circumference. With a second signal source you now will have 2 points where the signals overlap that you can be at.
A third signal point reduces it to a single point. The exact location of that single point is further refined by your timing of how long it took the signal to reach you. Of course, this calculation is for 2D. If you want elevation you will require a fourth signal point and instead of imagining 2D circles you will use a 3D sphere.
Charles Bernardo , 9 Sep 8: Possibly it would of been good to talk to a RF engineer or a carrier spokesperson on your information before printing it. These are evaluated daily by carriers to determine coverage and capacity issues. Federal Legislation under enhanced E requires an accuracy within ft of the handset.
Anonymous Coward , 9 Sep 9: There is a difference between a live query, where is this phone now, and the querying the much more limited data that the phone company stores. I would expect, and the statement suggests, that only very limited 'event data' is actually stored, like time and tower when a phone connects to and disconnects from a tower.
Mobile Phone GPS Tracking Technology
This makes perfect sense because of the orders of magnitude, 3 or 4, between 'event data' and second by second data from several towers. This may if useful to the company, include location data for the event, when they wish to survey coverage, or locate the boundaries of a black spot in there coverage.
Otherwise they would be storing data that they do not need, and that eats into their profits. This would not preclude them using live location data, if they could use it to sell customers to advertisers, but they would have no reason to store the data. Yes, not live tracking. All the talk about GPS location has confused the issue a bit. The devices can triangulate their live position from multiple towers or satellites for GPS and the device may relay that to a operator or Google, etc. However the information available to law enforcement weeks or months later is only what business records the phone company has chosen to keep.
This varies from company to company along with the retention period of records but normally it is a single tower location, a time and an antenna ID. Most towers are composed of three antennas offset to provide degrees of coverage, so each antenna ID corresponds to about degrees of sweep. Analysts can evaluate tower location for elevation, obstructions, and competing towers to provide rough estimates for the maximum distance from which a device is likely to connect.
It is generally several miles. This provides a large swath of coverage that the phone is deduced to have been inside of at that time. If the device quickly "bounces" back and forth between that and another tower or two the coverages may be overlaid to perform a crude "triangulation" but nothing close to GPS.
The odds that a device would bounce during any specific event, and that all the records would be kept, are pretty low. This information comes from my having served on a federal jury and being presented with phone record location information and analysis. I was very surprised at the time because I assumed it would be much, much better.
Thrudd , 9 Sep 8: Mathematics or in this case trigonometry at even a grade school level is not required to be a lawyer or work in law enforcement. As has been already documented, math science and logic are discouraged from an early age. As for the signal travel time - I highly doubt the dollar store towers would have that capability. You are stuck with needing a minimum of two to triangulate as long as you can get a direction. That is kyboshed to a 10 meter error by the USA. You can get better with the right surveying software and time OR receive the Russian signals OR wait for the EU to finish their system.
There is also ground based nodes in some cities that compensate for blocking LOS to the satellites.

Even that error can be reduced or eliminated by using fixed groundpoints. This speaks as much to the unfairness of the plea bargain system as it does to cell phone location technology. Someone being sufficiently frightened with false information so as to take 15 years for a crime they didn't commit invalidates the whole process. Don't think law enforcement and prosecutors didn't know they were spieling nonsense. They knew exactly how inaccurate the information was; they just didn't care, as long as it yielded a confession.
The existence of plea bargains is in my top 5 things that are the most harmful to actual justice, and leads to the conviction of innocent people. But if you're told that you'll be indicted for murder with possibility of the death penalty, you might be more inclined to do 15 years rather than risk losing your life. Agreed, pleaing some guilt rather than risk a false conviction by over-zealous prosecutors is not what our justice system is supposed to do. Unfortunately, I feel that I have too much cynicism in the authorities to ever be allowed on a jury.
First, 15 years is a substantial amount of time. Aside from that, though, a murder conviction effectively destroys your life whether you spend the next 15 years or the next years in prison. You're pretty much done for either way. Anonymous Coward , 9 Sep 1: Really getting confessions or plea bargins on false information should be a "twenty five years to life" felony offense. That shit is not acceptable at all. Not to mention it undermines the plea bargain system. If they can't be trusted on the evidence presented that gives reason for the accused to flood the courtrooms in case the DA really has nothing on them.
My Samsung Galaxy S3 running Android claims to use be able to use GPS, wi-fi, and mobile networks towers in order to determine its location. However, the phone I had in had no GPS capability whatsoever.

As I understand it, it can do this because it can see multiple towers and triangulate. The question--which still seems unanswered in the article and comment thread--is whether this works the other way. Can more than one cell tower "see" a phone and its signal strength at a given time? Or does the phone simply look for cell signals passively to decide which tower to connect to, meaning that only the connected tower sees the phone? If more than one cell tower can "see" a phone at a given time, the phone company would then be able to nail my phone's location to the same precision as I see on my phone, right?
In fact, they have to in order to make decisions about when and where to do handoffs to neighboring towers when the phone is in motion. Cell Tech , 10 Sep 8: John Fenderson's comment to pick just one is a perfect example. What one tower can see, the others cannot. A system operator would have to target a specific phone and force it to talk to several sites in turn. Each site can time a round trip, which the backend can then use to triangulate.
As far as knowing where everyone and their phone has been, cellular systems just store what sites every phone registers to and when. Once a phone has registered, the system does not know, or care, where in the service area the phone is. Phones only register on service area changes because that is what the system uses to know which sites the sites comprising your current service area have to page your phone when you get an incoming call or message. So no, they're not logging everyone's location with any geographical precision or on a frequent schedule.
Carl "Bear" Bussjaeger profile , 9 Sep What's actually happening in cell phone location is this: There are three separate processes used to locate a cell phone: TDOA doesn't do this because cell towers do not have moveable directional antennas you're reasonably safe in thinking of the array as an omnidirectional antenna. TDOA simply measures the time a cell phone signal takes to reach multiple towers. All the towers have their own GPS-based synchronized timing, so they can "confer" and agree that the signal each saw was the same connection attempt from the same phone, and compute the TDOA.
Distance gives a circle around each tower. The phone is where the arcs intersect. Number 2 is reasonably accurate to several tens of meters, which is good enough for E work. If you have enough GPS birds in view.
And you haven't had a glitch that puts you kilometers off the Florida coast as you head into Chi-town. I think most modern smart phones incorporate GPS some years back, a bright company finally built complete GPS receivers on a single chip , but not all phones have it, and GPS doesn't always yield a good location. Spaceman Spiff profile , 9 Sep And just how many people are in that area? That circle show the error range for your location as computed by your phone. It is not indicative of the error range for your location as computed by the telecom provider. You're comparing Granny Smith to Red Delicious.
Rekrul , 9 Sep 2: Most people are completely clueless about technology. Thanks to idiotic TV shows, people now destroy perfectly good hard drives instead of wiping them because they believe the stupid CSI shows that tell people you can never erase data off a drive. Why can't I access all that data? Info , 11 Oct You have 1TB of data, the data you remove is flagged as available space but it is not actually removed until it is in fact overwritten with other data.
Which is why you scrub mechanical drives with random data and even then you can recover some data if you're unlucky. That's also why the NSA and other agencies have a mechanical destruction policy on all HDD's leaving facilities after being declared unservicable. So all in all, i think the people doing that aren't that clueless about tech, you are. You fill her up, remove all data not scrub then place 20GB on it, the remaining GB still holds your previous data. Which is easily recovered by a few simple steps. Better way to do it is: Back when I was with Vodafone, I was always on the next tower up.
For example, I was in the suburb of Edmonton on the south side, connected to the White Rock tower to the north. When I went to Gordonvale, to the south, I was then connected for the first time to the Edmonton tower. I lived in Edmonton. I want you to remember this next time you're tempted to defend techno-utopianism. Dave Cortright profile , 9 Sep 9: I think the bigger issue that no one seems to be talking about here is that my phone is not physically tethered to me.
While I am with it much of the time, I sometimes leave it at home, in the car, at a friends, or even in a friend's car. Especially if there is no user activity on the phone, the onus is on the prosecution to prove that the phone was in fact with me at the time they claim it was in a particular area. Why wouldn't the cell tower know the distance of each client? I'm using wifi radios which are able to measure fairly precisely the distance between themselves and each attached client. Maybe that is why they bluff her As far as locating using one tower i dont think its impossible i just think its not a science simply because the towers serve a more profitable purpose.
Sonar does not use triangulation and is pretty precise. People just got better thing to make money at Because innocent people get convicted, and long prison sentences are scary. True, but irrelevant, since cell towers and sonar detectors don't work the same way. We have had several Android phones with GPS over the years, and some will be more accurate than others. I'd love to hear why, and see a review that compares accuracy of GPS across different models of phones, but I can't find that anywhere.
We care because we have an Autistic son, and it's really important for us to be able to locate him sometimes. I need to replace his phone, and I'd like one with accurate GPS. Brooke , 13 Oct 9: I want to add some info that why NSA is doing this. You will be clear after reading this article written by TheOneSpy cell phone spy software. Kim , 18 Oct 3: My husband tracks my location using FindmyiPhone. He has accused me of cheating on him because my phone says I am in one location when I am actually in another.
I don't know how to "prove" myself. Mercedes , 21 Oct 3: This is happening to my daughter right now, even a private investigator says there can be no mistake but she was not at the location it says either. Might cause a divorce. How do you prove yourself. Sue profile , 23 Nov 2: My boyfriend will ask me about a certain address and street and I am appalled by the fact he believes these stupid phone apps. Huge fights over it. I'don't like that I'may unable to prove myself to be correct. Piss on these fight starting piece of shit apps. But, it states location so it must be right.
Anonymous Coward , 25 Jan 7: You guys need to Google GPS and study how the system really operates. The forth satellite is for determining time, really?!! Lynn Arroyo , 17 Feb 8: I would love to know if there is any way for me to find out if a cell phone is, for example, located in the state of Georgia when the owner says they are in Colorado?
If you're not the owner, it's unlikely you'll be able to get this information. Anonymous Coward , 17 Feb I DID have my gps navigation on at the time my phone was lost. That's why it could be tracked so accurately. This article is about using cell site data to locate a phone, which is less precise and less reliable.
