Does not support modern metric measures Nice idea, poorly executed, it would have been useful if it supported metric measures. I have uninstalled.

A Google User

Koi Depot San Diego Love it...........must have calculator for any in the pond business or any one that has a pond!

Justin Long

Room For Much Improvement As Not Room On My S3 Screen Nice idea but not all of the buttons fit on my S3 screen. Also, it isn't clear whether you're sposed to input your length, width, depth etc in feet or metres. One of the variables is "max". Max what? Depth? Width? The 5th variable doesn't fit on the screen so its anyone's guess what it is. Without knowing, its impossible to use the calculation. Good idea but needs work.

Stuart Barrowcliff

Idea good but doesn't work When opened screen just goes Black. May be update for s4 would solve this

Lloyd Hodges

L. Hodges When evoking this app on my Galaxy S4 the app causes the display screen to go black. Is this app compatible with Galaxy S4 smart phone or not?

User reviews
