3D printing logbook · 100% offline

Every print, on the record.

A 3D print leaves no EXIF. Nothing records the nozzle temp, layer height and filament that produced a good part — so you re-derive it by trial and error. Layerlog keeps the whole fingerprint of every job, and finally tells you how many grams are actually left on the spool.

The problem

Your printer forgets. Every time.

“Which temp did I use for that part that actually worked?”
“Is there enough on this spool for a nine-hour print?”
“Why does this filament keep failing?”

No EXIF for prints

A photo stores its settings. A print stores nothing — the profile that worked lives only in your memory until it doesn't.

Spools have no fuel gauge

You cannot see remaining weight, so long prints die at hour seven and waste the filament already laid down.

Failures feel random

Without a record you cannot tell whether adhesion, clogs or one bad machine is really costing you time and material.

What's inside

A real logbook, not a notes app

Everything below runs on-device. No sync, no sign-in, no third-party SDKs — the app works identically in a basement workshop with no signal.

Core

Full print log

Model, printer, spool, duration, grams and outcome — success, partial or failed — for every job you run.

Core

Slicer settings captured

Nozzle diameter, layer height, nozzle and bed temperature, speed, infill and supports — the fingerprint you cannot otherwise recover.

Core

Filament inventory

Brand, material, colour, diameter, cost and — the number that matters — how many grams are genuinely left.

Core

Automatic weight ledger

Every logged print deducts its grams from the spool it used, then warns you before a roll runs out mid-job.

Core

Reusable presets

Turn a configuration that worked into a named preset and apply it to a new print in a single tap.

Core

Failure reasons

Adhesion, warping, layer shift, clogs, spaghetti, power loss — recorded per failure so the pattern becomes visible.

Insights & stats

Charts from your own log

Success-rate and filament trends over 7, 30, 90 or 365 days, plus KPI tiles for prints, hours, grams and cost.

Insights & stats

What actually fails

A ranked breakdown of failure causes, grams by material, and success rate per machine — so you fix the real problem.

Gamification

Streaks, goals & badges

Current and best printing streaks, a weekly hours target, a success-rate goal, and ten achievements to unlock.

Organization & search

Search, filter & tags

Full-text search across names, notes and tags, with filters for outcome, material, printer and pinned favourites.

Organization & search

Bulk actions & undo

Long-press to multi-select, then tag, archive or delete in one go — with an undo on every destructive action.

Customization & portability

Export & backup

JSON backups and CSV exports of your print log and inventory, written locally and shared on your terms.

Customization & portability

Make it yours

Light, dark or automatic theme, four workshop accent colours, and a compact layout for denser screens.

Core

Maintenance on real hours

Print time accumulates per machine, so nozzle changes and belt checks come due on actual usage, not a forgotten date.

Privacy

There is nothing to leak

Layerlog has no server. It is not a client for anything. Your workshop data never leaves the device it was typed into.

  • No data collected. The Play Data Safety form says "no data collected" because that is literally true.
  • No account, ever. There is no sign-up, no email, no profile — open the app and start logging.
  • One permission. INTERNET exists only so this privacy policy can be opened inside the app.
  • Encrypted on device. Notes are stored in an AES-encrypted database; settings use the Android keystore.
  • Yours to take. Export everything to JSON or CSV whenever you like, or wipe it all from Settings.
  • No ads, no analytics, no third-party SDKs. Free, with nothing to upsell.
