Kilnbook: Pottery Tracker
Kiln Log, Glaze & Clay Journal
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Every piece, glaze and firing in one place, with cone, shrinkage and firing-schedule calculators built in. No account: your studio stays on your iPhone.
Never wonder which glaze you used again. Kilnbook is the studio companion for potters: track every piece from wet clay to sold, log glaze layers by voice with muddy hands, and watch your firing live on the Lock Screen.
EVERY PIECE, EVERY STAGE
Snap a photo and the piece is logged. Kilnbook follows it through drying, bisque, glazing, the glaze firing and decals, reminds you when it should be bone dry, and tells you what is ready for the kiln. Series, photos at every stage, before and after.
GLAZES THAT REMEMBER
Keep every glaze with its recipe, photos and how it came out on each clay body. Scale recipes to any batch, check glaze fit (COE) against your clays, and see food-safety flags. Dictate layers ("two coats of celadon outside, white satin poured inside") and Kilnbook writes them down.
A KILN THAT PLANS ITSELF
Programs by cone or temperature, a shelf map with your own pieces, firing cost and safe-to-open time before you start. During the firing, a live countdown on the Lock Screen and in the Dynamic Island. After it, results by firing and by shelf, so the next load comes out better.
RUN YOUR STUDIO
Real cost and a suggested price for every piece, commission orders with due dates, students, classes and shared-studio shelves.
CALCULATORS BUILT IN
Cone chart, firing schedule, firing cost, kiln loading, shrinkage, throw-to size, drying time, recipe scaler, glaze fit and glaze expansion. Checked against primary sources.
YOUR DATA STAYS YOURS
No account. Everything is stored on your iPhone, backed up daily to Files, and exportable at any time. Kilnbook collects no data.
Also: home screen widgets, Apple Watch, Siri and Shortcuts, °C/°F and cm/inch.
FREE AND PRO
Free: the calculators, your glaze and clay library, a full sample studio to explore, and reading and exporting everything you have ever logged.
Kilnbook Pro adds your own pieces, stages and firings. Monthly or yearly, both starting with a 2-week free trial.
Payment is charged to your Apple Account when you confirm the purchase, or when the free trial ends. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours before that.
