About this app


Permission is required for 'Background location data usage' and access to files and photographs

This app (Tect O Trak) is designed to track and record the user's movements within the boundaries of a user-defined search area. The track recording feature will require consent to run location services in the background for long periods. The location data will be used to create breadcrumb type tracks on a map and also for coordinates when recording a find.

Tect O Trak also needs permission/consent to access photos, media and files. This is for photograph/image management which is essential for building a photographic journal type database

Tect O Trak does not access, seek to access, or require sensitive user information or any type of information

All data is stored only locally to this device, No data is gathered, monitored, uploaded, collected, shared, or viewable to anyone but the user. All data is strictly private and confidential.


Huawei smartphones aggressively close apps when you lock the screen.
Please adjust your device settings to allow Tect O Trak to run in the background.

Sadly, after six years, it has become necessary to withdraw the free version and replace it with a fully functional 28-day time trial version. This is to help ensure the continued development, maintenance and longevity of this very specialised application. I hope you have found Tect O Trak useful and worthy of your support.
If you are not in a position to support the app at the moment, it is recommended you do not allow any further updates and remain on Version V6.

Tect O Trak is an Android Gps track and finds recording application. Specifically designed for metal detectorists, by a detectorist. This is the app we were all waiting for. I got fed up with waiting, so I had a go at developing it myself! I hope you like it. Your feedback and support will be greatly appreciated.

This application allows the user to track and record their movements within a predefined area. Searches can be saved and resumed. Additionally, you can also mark/ revisit find spots, and make detailed photo and text records of your finds. You can also view and interact with your files on Google Earth using the Kml export tool.

You can view a demonstration video showing how to create a new search area and the find recording process here:- https://www.youtube.com/watch?v=uu2J29R3pg4

If you have the slightest issue, please contact me directly by email.

Tect O Trak has very nearly 5000 users and proven itself over the years and will work perfectly. If it doesn't, please don't hesitate to message me here:-MarkSeeleyUK@gmail.com

Ideally, you should turn on both GPS and Tect O Trak at least five minutes before you actually start detecting/recording. Let it track you moving around for a while. It's important that you are moving. This will give the GPS time to get a good fix on you. You will benefit from a more accurate starting point.

A personal message from the author.
I am not a professional developer. My interest is purely in metal detecting. Although I am the designer, I have to hire in people to do the actual hard coding. If you like Tect O Trak, please show your support by purchasing the app, also leaving a review in the playstore. This will go some way towards helping me develop the app further. I have lots more innovative ideas to implement, all dedicated to the specialised needs of the detectorist. With a little support from the community, it will be interesting to see how far I can take it!

Any questions, suggestions, ideas, or problems, please address to- MarkSeeleyUK@gmail.com

Be lucky,

ok, this app is good but needs a lot of work. contacted the author months ago but got no decent reply. Shame as the app would get five stars if it was designed a bit better. Setting markers is a pain, and trying to move and zoom the map can make you set a wrong marker. why not set up a simple wizard that allows you to go through a set up quickly and easily before you start the track? with this app is that the tracking lines don't work correctly on my Galaxy S9+ after the screen shuts off.

A great idea but unfortunately on my Moto g5 the location accuracy let's it down. Set to high accuracy and with a calibrated compass the accuracy is worse than 30m with the plot points jumping about randomly. The strange thing is that Google maps seems stable and accurate, it may just my phone I guess. Pity as it's currently unusable on my phone. Thanks for your prompt reply Mark. I take your point and have upgraded my review based on the potential of the app. I just need a better phone!

Hi George. GPS Locker will most definitely help. I assume you have the correct settings for your particular device regarding battery and background usage? Please contact me directly at markseeley@gmail.com if I can help you in any way. The de-defaulting coordinates system will be fixed. PS. Don't wait until the next hunt. Let's fix it now!!

What's new

This updates Tect O Trak for Android 10 and changes to the 'Run in background' (screen off) permission requirements.

Also, selected coordinate systems will become the default system until changed by the user. HH
