Home forge heat journal

Hearthmark

Log blades, hooks, and tongs with steel grades, heat cycles, quench notes, and stage photos — a personal rack journal built for shop-floor use.

Warm home forge with anvil and glowing steel

What the hearth holds

Everything you run at the home forge — pieces on the rack, heat you actually logged, and steel marks that worked.

Forge board

See every piece on the rack at a glance — open cycles, last quench, and steel mix in one warm dashboard built for home smiths.

Heat cycles

Record soak temperature, hold time, quench method, and temper so you can repeat a winning line six months later without guessing.

Recipe timeline

Build normalizing, hardening, and temper steps on a timeline, then copy a proven sequence onto a new blade or hook.

Stage gallery

Capture raw stock, forged shape, heat tint, and finished work with captions tied to each piece on your rack.

Steel ledger

Keep quench notes and temper windows for marks you actually run — 1084, 5160, and the grades behind your best jobs.

Hearth pulse

Summarize cycles logged, pieces still open, hottest soak, and steel mix when you want a quick read on shop activity.

On the shop floor

Track workpieces, log cycles, and browse your steel guide from a warm cream-and-gold interface made for the bench.

Hearthmark is a personal forge journal. The app does not collect personal data, run analytics, or transmit your journal entries to our servers. Content you create — workpieces, heat cycles, recipes, photos, and steel notes — is stored locally on your device.

If you contact us by email, we use your message only to respond to your request. We do not sell or share contact details with third parties for marketing.

Apple may process standard App Store purchase or device diagnostics according to its own policies; that processing is outside Hearthmark’s journal storage.
