Pile: Compost Ratio Calc
Browns to greens without the guesswork — EPA's rule for buckets, Cornell's 30:1 math for weights. Pay once.
What it does
Pile answers the compost question everyone argues about — how many browns to how many greens — and answers it honestly, because the two ways people measure need two different answers. The Mix Check and Compost Safe are free forever: counting buckets gets EPA's own rule (two to three times the browns by volume), weighing gets Cornell's real carbon-to-nitrogen math against the ideal ≈30:1, and the app never fakes one from the other. The free floor stays free: EPA's never-compost list, the 4–8 inch cover rule, why "compostable" cups don't break down in a backyard pile, and the damp-sponge moisture test.
