Heap: Compost Helper

Heap takes the guesswork out of composting. Add what you toss in - kitchen scraps, leaves, cardboard, grass clippings - and Heap calculates your carbon-to-nitrogen ratio in real time. No chemistry degree needed.

Free includes one active bin and the full reference library.

Features:

• Real-time C:N ratio calculator as you add materials
• Material library with C:N values for 236 materials
• Visual balance indicator: too green, too brown, or just right
• Turn and temperature logging to track decomposition progress
• Troubleshooting guide: smelly pile, slow breakdown, pests
• Composting method comparisons: hot, cold, vermicompost, bokashi
• Works offline - your data stays on your device

Heap Pro, a one-time purchase, adds unlimited bins, compost insights, harvest estimates, custom materials, saved recipes, and backup and restore.

Part of the Plant Anywhere family of gardening tools. Heap pairs naturally with the Plant Anywhere garden planner - grow food, then close the loop by composting your waste back into the soil.
