अब आप कटोरे के माप के टेप को फेंक सकते हैं और मापने के लिए खड़े हो सकते हैं।

No more going on your knees to measure distance between the bowling balls and jack.

With this app you hold the phone above the jack and click. The app will take a photo of the balls around the jack and will then display a Polar Grid over the photo.

The Polar grid has colour changeable lines for easier viewing in daylight and if there are other colour bowling balls.

The photos will not get saved on your phone so will not take up unnecessary space.
