TakeMeasure is a free Android app developed by Pressburg Associates that allows you to measure lengths of objects using just your camera. The app makes use of projective geometry to measure dimensions of any small or large objects from any angle. All you need to do is highlight a reference object such as a sheet of paper, card, or a banknote and the algorithm will do the rest.

TakeMeasure is incredibly easy to use and provides accurate measurements. The app is fully functional and available for free. However, if you want to support the developers, you can express your satisfaction by making a £1 donation through TakeMeasure Donate.

Overall, TakeMeasure is a useful and practical app for anyone who needs to measure lengths of objects on-the-go.
