    The app looks great, any news on the iphone version?

    • Mark says:

      Hi Andy, It’s still a little while off. 🙁 I will need backers to develop this very specialised, niche app. It will cost roughly about $2000 to get coded. There is an action group on facebook created to bring Tect O Trak to iOS. So far we have 68 out of 500 @ £3/$5 a pledge. If you would like to help, please visit and join

      Cheers ,

    Hi Mark,

    Any word on the iPhone version of your app yet? A friend of mine is just getting into detecting and he’s waiting for the iPhone app.

    I myself have been using your app on an android system for about a year now. The only problem I find is location accuracy, at times I can be up to 9 metres out. Other than that I love its functionality.

    I have been using tect o trak for some time now, I find it an invaluable tool. Is there a way that you can reduce the space between the dots on tracking so that it gives you a more accurate plot.

    • Mark says:

      Hi Paul,

      I’m not sure it will give you a more accurate plot.

      The track recording is really designed to be used in a specific way to get the most accurate/reliable results given the limitations and exact preciseness of GPS.

      At the moment the app is scaled to detecting open country farm fields in the UK. The spacing between the dots is finely balanced to allow you to stop without it jumping around and leaving random dots as you investigate/dig a target. You can then continue without it disturbing the flow of your line. Keeping to ‘clean long lines’ and the eventual use of the ‘Pathfinder’ tool makes it easier to find the best lines to take when the screen starts to get crowded further down the line.

      Users are advised to:- Always detect in straight lines whenever possible. When you want to change directions, STOP. Turn to face the new direction, Choose a far target to aim at. Choose a nearer target that’s in line with the far target, then start walking towards them keeping them both perfectly in line. A new inline middle target can be set along the way. I assure you this way will give the best results. It stands to reason that reducing variables to ‘linear only’ reduces potential error by 50 % 😉 The results are there for you to see. If you walk a straight line and it shows a straight line, then something must be right. That is much preferable to the uncertainty of a curve/turn given the signal delay time. At least on a linear path, you are either ahead or behind time but still on the same line. I hope this makes sense? 🙂

      However, having said all that.

      . There have been enough requests over time for a faster GPS refresh rate and closer dots, that I am going to add it as a user option in the next update. Personally, I think it’s just adding more potential for error and too much is being expected from GPS. It’s good, but it’s not “Beam me up Scotty” good. Yet… 😉 I could be wrong. We will see.

    Hi Mark,
    Bought the android version – I used the Lite but the paid version is well worth it. Just a question for an old man – where is the Tect O Trak folder on my phone? Or, how do I find it?
    I click export and it says done. I click back up and it says done. But where? It is connected to my PC, Win10.
    Many thanks!

    Congratulations on an overall great app, there is one irritating problem for me however, when I close the app, it continues to use location services until I manually close the app. Is there any way to stop location services when you come out of the app?

    Thank you

    • Mark says:

      Hi Paul,
      Unfortunately, the app had no control or influence over location services. For example, if you start the app without GPS on you will get an Android system notification asking if you want to turn location services on. You have to say manually agree to this. It cannot be fully automated for android security reasons. It’s the same with turning location services off. You have to manually do it yourself. I could probably prompt the android system to ask you if you want it to turn location services off when exiting? However, it would be best if the user can accept he is the ultimate lord and master of GPS/location services and assume the responsibility themselves 🙂

    I now understand that you use the iOS version. To be honest I’m not very clued up about iOS systems. If you are a Facebook user, please consider joining the Tect O Trak user group:-
    you will be able to get all the advice and help you need there.

    Unfortunately, the update I mentioned is only for the Android version on this occasion, but there will be many other IOS updates in the future for sure.
