Trace a pond from a photo, get its volume and surface area, then plan the yard around it. Everything below runs from that same traced geometry, so the numbers in the calculators and the shape in Studio come from what you actually measured, not a separate estimate.
Trace the rim and each depth layer over your own photo or a satellite image of the site. Two tape measurements set the scale, and the tracer corrects for camera angle and height so the outline maps to real inches. Volume and surface area come from that traced shape, not a length-times-width guess.
The same measured pond opens in a 3D scene with the surrounding yard: houses, decks, paths, planting beds, and pond equipment. Shoreline material, water appearance, and camera view are adjustable without changing the underlying geometry, so the volume stays correct while you try different looks.
Volume, salt dosing, liner size, surface area, stocking, pump sizing, ammonia, and water change amount. Each one can read measurements from a saved pond instead of retyping them.
Ponds are saved on your device. Keep more than one design for the same yard, compare them side by side, and export a project file to back it up or move it to another device.
Signing in with Google keeps a pond available across devices. A free account covers one pond up to 3,000 gallons and three depth layers. A one-time purchase removes that limit for one property. A subscription covers multiple properties, for anyone managing more than one yard.
