SELLING TIMBER IN THE EU?
Timberlog also keeps EUDR harvest records and prepares the simplified due diligence statement, with plot geolocation (GeoJSON) and a 5-year reference number vault. It helps you collect data; it is not legal advice, and you submit the statement yourself in the official EU system.
FREE + PRO
Measuring and calculating are free. Pro removes ads and unlocks cut back, price per log, unlimited photo measurements, editing and EUDR export.
Very useful but need to have option to remove ads.
Developer Response
In a paid version you have this option.
Doyle Scale isn’t accurate
Log seller
The scale rounds down to the nearest board foot, not up. Doesn’t match the printed graphs of Doyle scale. Ie) 11’x19” log should be 154.68 according to Doyle formula. Printed charts round up to 155bf. This ap rounded down to 154bf.
Developer Response
Thank you for reporting this with such a precise example. You're right, the 11' × 19" log should show 155 bf, not 154. I've fixed this in version 1.13.1, now available on the App Store. If the update solves it for you, I'd appreciate it if you'd consider updating your review.
- Work statistics: volume measured per day, week, month and year; detailed view by customer with Excel export (Pro)
- Share card: post your statistics or a measured pile as an image on social media
- New role in quick setup: forester
- One short, optional question about your work (you can skip it)
New in 1.15:
- Company logo (Pro): your logo at the top of reports (print, PDF and Excel) and EUDR printouts
- New report look: a letterhead with your company details, bold column headers, shaded rows and bold totals
- Totals and prices show a thousands separator and the currency symbol where you expect it: $18,221.30
- Main screen with large system text (Larger Text): the input fields no longer get cut off; the price moves to its own line
- Tap a log in the list to edit it (long press still works)
- Cut back: the fields now sit directly under length and diameter, with no extra caption
