Most composting apps give everyone the same advice. Layers doesn't — because a worm bin isn't a hot pile, and a bokashi bucket should never be turned. Layers is the composting companion that actually knows your method. Choose from six approaches — hot (thermophilic), vermicomposting, bokashi, cold composting, tumbler, or Johnson-Su bioreactor — and every temperature target, moisture range, reminder, and recommendation adapts to how you actually compost. TRACK WHAT MATTERS Log temperature, moisture, turns, and photos in seconds Method-specific guidance that flags problems before they ruin a batch Weather-aware recommendations for outdoor piles, powered by Apple Weather YOUR COMPOST, EVERYWHERE Home screen widgets show your pile's latest temperature and status Lock Screen widgets with method-aware countdowns — "Turn in 2 days" for hot piles, ferment-day tracking for bokashi Live Activities pin an active pile to your Lock Screen and Dynamic Island SEE IT THROUGH A proper curing phase with guidance tuned for resting compost Harvest flow that records your yield and celebrates the finish Shareable run summaries: temperature curve, turn count, and photo timeline of the whole batch GET BETTER EVERY BATCH Analytics dashboard across all your projects Batch comparison: overlay temperature and moisture curves from past piles to learn what made your best batch your best Recipe builder with C:N ratio calculations for a perfect mix from day one AND THE ESSENTIALS Smart notifications that respect your method — no turn reminders for a worm bin iCloud sync across your devices Full data export From your first kitchen-scrap bucket to a farm-scale Johnson-Su operation, Layers meets you where you compost.
