Six composting methods, one app that knows the difference. Track temperature, moisture, and turns with guidance built for how you actually compost.
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.

What's New in Layers 2.1
Your compost, at a glance — this update brings Layers to your home screen, Lock Screen, and beyond.
Widgets
See your pile's latest temperature and status without opening the app. The Lock Screen widget knows your method: hot composters get turn reminders ("Turn in 2 days"), bokashi buckets count down the ferment, and Johnson-Su bioreactors show their day count — because you're never turning those.
Live Activities
Pin a project to your Lock Screen and Dynamic Island. Log a reading and watch it update instantly — perfect for tracking a pile through its hot phase.
Harvest Flow
Finishing a batch is a moment worth celebrating. Complete a project to record your yield and get a full run summary: temperature curve, turn count, photo timeline, and total days. Share it as an image and show off your black gold.
Curing Phase
Real compost doesn't go straight from active to done. Mark a pile as curing and Layers adapts — no more turn reminders, moisture guidance tuned for the resting phase, and a heads-up if your pile reheats. Bokashi users get a dedicated soil integration stage.
Batch Comparison
Compare up to four batches of the same method side by side. Overlay temperature and moisture curves, see who hit peak temp first, and figure out what made your best batch your best.
Plus bug fixes and performance improvements. Happy composting!
