Pilewise works out the compost math before you guess: blend your feedstocks to the right carbon-to-nitrogen ratio and moisture, see a live verdict, and get exactly what to add to fix it. Add your greens (nitrogen-rich) and browns (carbon-rich) by weight (kg/lb) or volume (litres/buckets/US gallons), and Pilewise works out the blended C:N ratio and moisture as you go.

Features

Live verdict: ideal, acceptable or needs adjusting — for both the C:N ratio and the moisture
Solver: exactly how much of a chosen material to add to reach your target ratio, or water or dry material to fix the moisture
A 41-material feedstock library — greens, browns and manures with real published values and sources — plus your own materials with your own numbers
Enter by weight or by volume, converted with each material's density
Several piles (heap, bin or tumbler), each with its own log: turns, temperature, moisture feel and notes
Optional turn reminder, any interval you choose, at a time you choose
Metric and imperial, switch any time without losing what you typed
Back up your piles, materials and settings to a file, and restore them later
Light and dark themes, large touch targets

For home gardeners and allotment holders who want compost that heats up and finishes, instead of going slimy or sitting there for a year.

Pilewise works offline: no account, no sign-in, and your piles and log stay on your phone.
