GPS tracker in iPhone

I was always interested in the topic of GPS / GPRS trackers. And since I like to walk a lot more, from time to time I thought about buying a wearable tracker so that when I got home, I could see the path traveled.

This topic is written in note mode.
I share the information that there is such a program.

But a separate device has disadvantages: you should always take it with you, keep it charged, as a rule, such trackers do not work online (i.e., do not send coordinates immediately to the server via gprs)
')
I was delighted when I found out about the free program in the AppStore. It is installed on the phone and sends the coordinates to someone's server, and this server then kindly shows the coordinates on the map. Everything is absolutely free.

Here is a brief list of features that I turned my attention to:

• Full battery discharges hours in 7-8
• It cannot work in the background (probably only if there is a jailbreak and the corresponding software), but with the screen turned off it works completely
• Data on the site arrive with a delay of no more than 5 seconds
• Having conducted an experiment on traffic, I found that in 4 hours of walking and 2 hours of driving in a car I spent a total of ~ 3 rubles. (Megaphone, O-Light)
• By the way, there are customers for other phones

And you can also insert a card on any page through the iframe. I immediately built this page on my blog

And next time I will tell you how to do almost the same thing, but with your own hands. The photo below shows a GPS / GPRS tracker with 2 external antennas (GPS + GSM), powered by 12V. Inside the sim508 module. The story of how I chose the tracker, how I tested it, how I received data on my server and processed it. The conclusion is also - Google Maps, the functionality is the same as on the site, which was discussed a little earlier.
