Frequently Asked Questions

(i) get a good recent Android phone or tablet, with a good camera (min 8 megapixels), at least Android >= 5 and 3,5GB of RAM. We recommend the following phones: Samsung Galaxy S10 / S10 Plus / S9 / S9 Plus / Note 8 / Note 9. If the idea is to measure offline then its best to have a bigger screen and the Samsung Note 9 is a good choice. We also recommend if you buy the Samsung Note 9 to also buy the S-Pen that goes with it. If you plan to do all measurements online then it's best to take a phone because the cameras are usually better.
(ii) Download the Tally Express mobile app from Play Store. To find it type ”TallyExpress” in 1 word in the search bar of the Play Store.
(iii) Order our plastic references
(iv) Check our video tutorials on the homepage
(v) Start taking pictures and measuring your lumber bundles.

For accurate results, TallyExpress must be installed on a device with a high quality camera (minimum 8 megapixels) and a strong processor, with at least 3.5 GB of RAM memory.We recommend the following phones: Samsung Galaxy S9 / S9 Plus / S10 / S10 Plus / Note 9 and the tablet: Samsung Galaxy Tab S4

If the idea is to measure offline then its best to have a tablet (bigger screen). If you plan to do all measurements online then it's best to take a phone because the cameras are usually better.

You can export your tally files in xls or pdf by e-mail. We can also connect our system with your inventory system through our API. Ask your inventory software partner to contact us and we will take care of this. We charge an additional yearly amount of 2000 USD for this connection.

The software is not perfect and you will need, in some cases, to check/edit the results. There are 2 ways to do this:

After you take the picture and when filling in the form with details of the bundle you can enter different lengths. Enter first the length you have most since this is the one that the software will use per default for all boards.

If you measure offline you will be able in the last step, to mark the odd lengths on the screen of your device. Our clients usually work in one of the following ways:

  • They mark the odd lengths at the end of the boards. In this case the user can stay on the front side of the bundle and tap on his screen the odd lengths on the relevant boards. So for ex if there is a majority of 7ft and then a lower number of 8ft the software will allow you to indicate only the 8ft boards on the screen.
  • If you are used to first count the odd lengths and then consider that the first X boards are of that length this can also be done.
  • If the odd lengths are not marked, the user can go to the back of the bundle, flip the picture he already took to see the boards as he sees them at the back, then use his finger to mark the odd length boards on the screen.

If you measure online you will be able to work as described in the first 2 bullet points above.
We are currently working on recognizing automatically marks at the end of boards… more on this soon.

After taking the picture and entering the details of the bundle, we added a button which looks like a clock and which you can use to save incomplete measurements. When clicking on this button, the measurement will appear with an orange flag instead of red one in the list of measurements. After this, you can simply go back to it and measure it at a later time, offline or online.

Now you can see both gross & net values in TallyExpress. We added the option to set a shrinkage factor, default to 8%. In order to enable it, you have to go to the three dots on the top right side -> Global Settings -> check the "Shrinkage factor" checkbox.Further on, if you want to see net values instead of gross values, go to Settings and check the "Net values" checkbox.

You can share and export your measurement tally reports from both web and mobile app. Just go on any measurement and click on "Export". You will be then prompted to choose how you want to export it: by email, pdf, or .xls file.

Since the app gives results up to 1/16th of an inch precision, in the tally report the values are rounded. We have more than one method for doing so, besides the classic rounding at 0.5 inches. If you let us know how you build your tally reports, we can implement the same rounding in your version of the application.

If you are checking the pictures on you web interface and notice that something went wrong with one of your bundles, you can mark the measurement and the employees taking the pictures in the warehouse will be notified. To do so, in the first editing step, where you mark the corners of the bundle, there is a button called “Redo measurement”. it is located on the right side, between the “Zoom in” button and the “View original image” button. Once clicked, it turns red and the measurement is marked as “Needs to be redone”.

By default, the volume is calculated using the thickness you added in the measurement details screen. This means that if you added 1 inch as the thickness, all the planks will be considered to be of 1 inch thickness, even though some of them might be 1 1/16 inches or 15/16 inches. To calculate the volume using the real height, detected by the algorithm behind TallyExpress, you can go to Global Settings -> Weight calculation thickness and select “Real thickness” instead of “User thickness”.

Go to and buy it directly from there. We will then ship it to the address you specify as “Delivery address”.

You can add new species or rename existing ones by going to your web storage module. Go to -> Settings -> Planks and customise all the properties linked to a measurement: Species, Qualities, Colors, Cuts, Dry status, Surfaces or Specifications.

In order to use TallyExpress on a new device, you have to disconnect the old one first from your account. To do so, go to your web storage module -> Settings -> Devices and unlink the device you no longer user. After doing so, you will be able to connect with your new device to the same account.

Yes, you can do so by going to Settings -> Unit system and change it according to your needs.

On TallyExpress you can choose how many measurements to save on the phone / tablet. Go to Settings -> Sync limit and choose whichever limit suits you. Keep in mind that on the web you will see all your measurements at all times.

TallyExpress gives you the option to group your measurements based on various criterias: warehouses, custom groups or category (Incoming / Outgoing). To see these options in your measurement details form, go to Settings and check the checkboxes for the options you want added.

  • Red chips need to be on top
  • Reference needs to be fully contained inside the bundle & placed in center
  • Reference needs to be hanging in the form of a diamond

We have found that best results are obtained when the bundle occupies around 70-80% of the image. It is extremely important that the entire bundle is visible in the picture (otherwise, there will be missing boards which will result in inaccurate tallies). If the user stays too far away from the bundle, the app will notify the person taking the picture that he / she is too far and should move closer in order to get the best results possible.

The background is not extremely important, since the software knows to distinguish between wood boards and background. The algorithms detect the bundle margins and the boards and are not affected by the environment. However, the lighting is very important; it is essential that the boards are not covered by very dark shadows and the environment itself is not very dark. If the boards are visible for a human looking at the picture, then our software should be able to detect them. We have tested the detection outside, in sunny / cloudy weather, as well as inside, with artificial light, and the results were good.

Step by step


Start TallyExpress app


Place the reference on the bundle


Take a picture of the bundle with your phone or tablet


The app counts the boards, their dimensions, total volume and produces a tally report with picture.
