App Description

Partometer is a useful and handy camera tool for object dimensions measurements that can be used as a ruler or tape measure on your iPhone.
The App performs remote, non-contact in plane measurements. It uses the phone camera and any available object with known size as a reference. Most common objects like credit card, sheet of paper, DVD/CD, etc. are included in the application. Moreover you can use your own custom objects with known size.

The user has an option to make a snapshot of the camera view and work with the image instead of live camera view. Picture upload from the picture gallery is also available.

The following mode are available in the app:

Length Mode: measure objects in any direction and compare parts to each other.

Angle Mode: two rulers are available connected in one point to measure angle and lengths.

Area Mode: area of irregular shaped objects can be calculated using this mode.

Circle Mode: measurements on circle - radius, length, area

The App shows measurement results in different units such as meters, millimeters, centimeters, feet, inches based on user settings. It also calculate dimensions of the object in relative units with respect to the reference object.

Two editing modes Edit and Zoom help the user to align the rulers or to mark an object accurately.

The App can be very useful if you need to measure bigger distances on a plane, where a simple ruler or measure tape is difficult to apply. All you need to do in this case is to place the reference object (credit card or sheet of paper) on the measurement plane, to make sure that an object of interest and reference object fit into the camera view, to take picture and do measurements.

- estimate Pupilary Distance by holding credit card next to your face
- measure fish size very quickly or measure all previous catch from the pictures using your own height
- measure fabric or cloth area and size
- measure trees
- measure angles, pitch gauge
- measure spark plug gap
- measure area of irregular shaped objects
- measure bearings, roller bearings, nuts, rings.
- measure any internal feature or irregular shaped area on X-ray if you have a reference( useful for dentists)
- make measurements in different units
- measurements of small objects that fit within your device screen: jewelry, rings, stones, screws, bolts, buttons, nuts, knitting needles, knitting pattern, washers, insects, mosaic tile, hooks, etc.
