A handy little app that displays a chart at 1:1 scale so that you can accurately measure hail stones according to the National Weather Service Standards. Includes all the latest recognized sizes for proper reporting of hail sizes.
No need to carry a ruler or other objects to photograph and record hail. Report accurately to the NWS and eliminates guessing. Use Rapid Report to photograph and upload your report to the NWS, Facebook and Twitter.

Sizes included in chart are:
0.25" (Pea) Size Hail
0.75" (Penny) Size Hail
0.88" (Nickel) Size Hail
1.00" (Quarter) Size Hail
1.25" (Half Dollar) Size Hail
1.50" (Walnut) Size Hail
1.75" (Golf Ball) Size Hail
2.00" (Hen Egg) Size Hail
2.50" (Tennis Ball) Size Hail
2.75" (Baseball) Size Hail
3.00" (Tea Cup) Size Hail
4.00" (Grapefruit) Size Hail

Some users have reported inaccuracies in the ruler scales on the image.
To overcome this use the Calibrate Button in the upper left. Have a real ruler on hand for a one-time setup.
Your settings will be saved from each use so you don't have to redo the calibration each time.
If the ruler dimensions on the display are not matching up to a real ruler do the following:
1) Hold a ruler up to the scale and note if the image is larger or smaller than the ruler.
2) Press Calibrate
3) Pinch the image larger or smaller as needed.
4) Press Save
5) Check again with the ruler. If still off repeat steps 1 - 4

True hail sizer. Lots handier than other means of measure when chasing or simply observing, reporting. Awesome little helper.


Hail scale Great tool for weather scale in the construction, & Safety industry. Love it! ;-)

Terry Eckman

Awesome Will be really useful in the field during the chase season

Convenient little app The new calibration feature makes this work flawlessly on my HP Touchpad running Cyanogen Android 4.04. Using a ruler to calibrate it, I have it scaled to match within 1/16" over a 7 inch range, which is more than sufficient to be accurate for all hail sizes. This is a lot more convenient than carrying around a caliper or a printed & laminated comparison size chart!

Nice app The calibration update is excellent. Beware if you use a battery bar will throw off the calibration; so it must be disabled for the setting the calibration and properly applying the calibration. Hope everyone is willing to put melting hail near their electronics!

App works well App works well! Will come in handy this chase season!

Does not save calibration Motorola Droid Turbo After tapping save, reverts to previous calibration. Tried a few times.
