Heap: Compost Tracker & Guide

Heap takes the guesswork out of composting. Whether you're managing a backyard bin, a tumbler, or a full-scale hot pile, Heap tracks your carbon-to-nitrogen ratio in real time so you get rich, dark compost, not a smelly mess.

REAL-TIME C:N RATIO CALCULATOR
Add what you toss in, kitchen scraps, coffee grounds, eggshells, leaves, cardboard, grass clippings, sawdust, straw, and Heap instantly calculates your carbon-to-nitrogen balance. A visual indicator shows whether your pile is too green, too brown, or just right. No chemistry degree needed.

TRACK MULTIPLE BINS
Manage compost bins, tumblers, worm farms, and open piles all in one place. Name each one, log turns, record temperatures, and track how each pile progresses from raw waste to finished humus. Free includes one active bin and the full reference library.

236 MATERIAL LIBRARY
Look up the C:N ratio for 236 composting inputs: fruit peels, vegetable scraps, newspaper, wood chips, manure, seaweed, dryer lint, and more. Each entry shows whether it counts as green (nitrogen-rich) or brown (carbon-rich) material.

COMPOSTING METHODS
Compare hot composting, cold composting, vermicomposting, and bokashi side by side. Heap explains the tradeoffs, speed, effort, space, and smell, so you can pick the method that fits your yard, balcony, or kitchen counter.

TROUBLESHOOTING GUIDE
Pile too wet? Smells like ammonia? Not breaking down? Attracting flies or pests? Heap's troubleshooting section diagnoses common compost problems and suggests fixes based on your pile's current C:N balance.

TEMPERATURE & TURN LOGGING
Track internal pile temperature over time to know when your hot compost is cooking and when it needs turning. Log each turn with date and notes to build a complete composting history.
