KilnNote
Read full descriptionHide full description
Bring your winning recipe to the next piece. KilnNote is a pottery record-keeping app for glazes, firing logs, and progress tracking. "I nailed that celadon combo once — and then I couldn't reproduce it." Sound familiar? KilnNote keeps every glaze, clay, and firing detail in one place so you can reproduce what worked. 【What you can do】 ▷ Log works piece by piece Save bisque, glaze application, and final firing temps, glazes used, and results (Success / Review / Fail) as a step-by-step log. Every decision, always at hand. ▷ Progress at a glance Auto-status from the latest firing result — Success, Review, Fail, or Not Started. See it in the list or detail view instantly. ▷ Tags & search Organize works with free tags like "Exhibition" or "Class piece." Filter by tag or title, and the search state stays put as you navigate. ▷ Glaze master Record glaze name, maker, and color notes — plus attach a glaze sample photo. From each glaze, trace every piece and firing that used it. ▷ Pinch-to-zoom Zoom into work, firing, and glaze sample photos to check texture and color up close. ▷ Export & import (free) Back up as CSV, PDF, or photo ZIP. Import from CSV or ZIP. Great for device migration or class notes. ▷ Board view (Pro) See all works organized by status — Success, Review, Fail, Not Started — like pieces arranged on a studio shelf. ▷ Test piece comparison (Pro) Slide between two photos to compare glaze colors and textures side by side. ▷ Duplicate a work (Pro) Clone a successful work as a template. Carry the same firing steps into a new piece. 【Who it's for】 ・Potters who want to reproduce a glaze success ・Studio potters managing multiple test tiles ・Beginners who want to track what they learned in class ・Anyone who can't remember which glaze combo worked last time ・Home potters who want a private, offline log 【Your data stays on your device】 All work data, photos, and firing logs are stored locally on your iPhone/iPad. Nothing is sent to external servers. No account required. 【Pricing】 ・Free: Up to 5 works. Core logging, CSV/PDF/ZIP export, and data import at no cost. ・Pro (one-time purchase): Unlimited works, board view, comparison, duplication. Buy once — no subscription, no recurring fees. ------------------ Developer: Kore Apps Support: support@kore-apps.com ------------------
Ruten

RUTEN — drifting life and time A small planet, viewed from space. On a sphere, six lineages of life live within their own food chain. Closer to red: stronger, more predatory. Closer to blue: more numerous, gentler. Pillars of light (lifestreams) rise from continents, where life springs forth. At the center floats the era, lunar month, solar term, and a kanji-numeral clock. Occasionally, a meditation bell in a Japanese pentatonic scale chimes "pohn" (optional). >Modes ・Ranman — vivid blue Earth, abundant life darting and fleeing ・Wabi-Sabi — a translucent skeletal planet, sparse life walking quietly >Features ・Tap a creature to mark it as your favorite — it becomes immortal ・Home Screen widgets (small/medium/large) for daily seasonal notes ・Quiet notifications on each of the 24 solar terms (optional) ・Japanese / English >Philosophy Heraclitus's "everything flows" meets Kamo no Chomei's "the river flows ever onward": two voices a millennium apart, placed on the same sphere. This app accomplishes nothing. It is a place to gaze, and surrender to the flow.
