Plytrail

Follow fiber through singles, bobbins, partial plying and finished skeins. Reuse a bobbin while keeping its material history, and find the source fiber and settings behind your finished yarn.

Keep notes, photos, equipment settings and timed spinning sessions together. Record WPI, compare measurements before and after finishing, and review grist — the relationship between yarn length and weight. Choose grams or ounces and meters or yards independently, with light and dark appearance.

Start free with 3 active projects and 10 standalone fiber batches. The complete spinning workflow, bobbins, sessions, photos, basic PDF skein labels, and full backup and restore are included. Archive a project to free an active place. Existing work stays available to edit, finish and export, including after restoring a journal above the free creation limits.

Optional one-time Pro removes limits on new active projects and standalone fiber batches, and adds named recipe templates. The planned price is EUR 14.99 or USD 14.99, without a subscription; Google Play will show the final local price before purchase. Viewing a finished skein’s settings and starting from them within your free project places are already free.

Save a complete ZIP journal backup with linked photos, export a fiber list as CSV, share a text recipe or make a simple PDF skein label. Backups are readable and unencrypted. Restoring a backup replaces the journal on that device, so keep a copy of current work first. Restore a Pro purchase separately through Google Play; it does not restore your journal.

Use the journal offline without a Plytrail account or advertising. Backups are manual, with no automatic cloud sync; a file provider you choose may use its own cloud service. Google Play handles Pro purchases, purchase checks and technical billing diagnostics. Read the privacy policy for photo metadata, storage and deletion details.
