Kilnly

Offline pottery studio logbook

Fire it again, exactly.

A finished pot records nothing about how it was made. Kilnly is where the glaze layers, the clay body, the firing schedule and the result actually live — so a surface you loved is repeatable, and one that crawled is avoidable.

The pot is finished. The recipe is gone.

You dipped one glaze over another, fired to a cone on a particular ramp and hold, in a particular kiln — and the result arrives days later, long after the decisions. Studio notebooks get clay on them. Shared kilns lose track of whose load was whose. Clay shrinks and the mug comes out the wrong size.

“Which one was on the bottom — the satin white or the celadon?”

The question Kilnly exists to answer.

Everything a studio actually needs to remember

Insights, streaks, search and backups — all computed on the device, with no account and no network.

The piece pipeline

Greenware, drying, bisque, glazed, glaze-fired, finished. Each piece carries its form, clay body, clay weight and dimensions.

Glaze layers, in order

Record exactly what went over what, how many coats and by which method — the detail no pot preserves.

Recipes with a batch calculator

Store materials as percentages, then scale the whole recipe to any dry batch weight. Kilnly normalises totals and estimates cost.

Firing schedules

Log every segment — ramp rate, target and hold — plus the cone the pack actually reached, the atmosphere and the duration.

Insights & charts

Success-rate trends per firing, pieces per month, defect breakdowns and per-glaze drill-downs — all from your own history.

What actually worked

Kilnly ranks your glaze × cone × kiln combinations by how often they came out well, so the good result is reproducible.

Shrinkage that's measured

Wet, dry and fired test-bar measurements per clay body give you a real shrinkage percentage instead of a guess.

Today & upcoming

An in-app agenda for pieces that have sat too long, firings waiting to be unloaded and kiln servicing that has come due. No push notifications.

Tags, search, filters

Full-text search across pieces, glazes and firings, with tag filters, sorting, pinning and archive-with-undo.

Kiln maintenance on hours

Elements, kiln wash and thermocouples come due on accumulated firing hours — the thing that actually wears them — not on dates.

Export & backup

Write a full JSON backup or a readable CSV to your own device and share it anywhere. Restore it later. No cloud involved.

Streaks, goals & badges

Weekly bench-session streaks, monthly piece and firing goals, and twelve achievements unlocked by real studio milestones.

Your studio, remembered.

Kilnly runs entirely on your phone. No sign-up, no sync, nothing leaves the device — which is exactly what you want in a studio with no signal.
