SeamSlate

SeamSlate

Record sewing machines, fixed test contexts, sequential runs, observed outcomes, frozen setup cards, maintenance facts, and immutable corrections in a private offline ledger.

iPhone and iPad
Local-first

Keep each test context intact

Freeze the machine, fabric layers, needle, thread, and presser foot when testing begins, then record each stitch, numeric setting, observation, outcome, and selected photo in sequence.

Turn a useful run into a durable card

Mark an outcome yourself and freeze a Ready run as a setup card. Corrections, voids, restores, source links, and maintenance facts remain visible without silently rewriting the original record.

Search facts and own the backup

Search the local ledger, compare neutral run values, review time-window facts, and export text or CSV. Complete SHA-256-verified backups support preview, merge, replace, and restart-safe rollback.
