Now you can count stacks of hollow pipes and tubes quickly from your mobile device. Simply open the CountPipes app, take a photo of the stack you would like to count and press the “Count” button. Using advanced computer vision technology, CountPipes tags each counted pipe with a number so you can easily verify and document the results. Mistakes are easy to fix. Just review the count and adjust the tags to ensure accuracy. Get the app for free and start counting up to 10 pipes per photo to see how it works. When you are ready to use the app for your business, create an account within the app and select a plan based on the number of pipes you would like to count per photo. The CountPipes app uses Machine Learning technology to identify and count pipes. If the images of your pipes differ from the images the app was "trained" to recognize, we will need to craft a Counting Template specifically for you. In order to proceed, send us some sample images of pipes you would like to count. Contact us for a custom demo with your photos plus a 14-day free trial.

Take a new photo or pick a photo from your photo library and then count objects on it by tapping them. Save screenshots and/or share them via email or social networks. Use the Line tool when you need to mark a sequence of objects with equal distances between them (note: this doesn't work well with object viewed in perspective).
