Measure logs and sawn timber in seconds. 20+ scaling standards, weight estimates, Excel and PDF reports — the field calculator built for foresters, loggers, and timber buyers. Timberlog turns diameter and length into precise volume in board feet, cubic feet (CFT), or cubic meters — one-handed, clearly readable in bright sunlight. MEASURE ANY WAY YOU WORK • Round timber: log volume from diameter (or circumference) and length • Photo measurement: point your camera at a log pile — log count, diameters, and volume detected automatically • Review detections with a tap: exclude, restore, or add any log the camera missed • Sawn lumber (boards, planks, beams): width × thickness × length • Firewood estimation and stack volume • Standing tree volume by Noonan (Kershaw) • Bark thickness deduction and wood weight estimates LOG RULES & SCALING STANDARDS Doyle Log Rule, Scribner Decimal C, International 1/4", Ontario Scaler's Rule, Roy Log Rule, Cedar Log Scale (2/3 Rule), Hoppus (Quarter Girth), Huber, Smalian, JAS, GOST 2708-75, ISO 4480-83, ČSN/STN 48 0009, NF B53-020, plus local Czech/Slovak and Hungarian species volume tables. FROM LOGS TO A PRICED LIST • Tag every log with species, grade, and assortment • Scan a barcode or QR code to tag logs instantly • Set prices per species and grade, with tax — see the load's value as you scale • Average diameter, total volume, and weight at a glance • Add customer and company details to your reports • Work with multiple lists open at once for fast job switching • Share lists by email, other apps, or cloud • Export to Excel, print reports, or save as PDF EUDR — READY FOR THE EU DEFORESTATION REGULATION From 30 Dec 2026, selling timber in the EU requires a due diligence statement. Timberlog: • enter permits in two minutes — by QR scan (Slovenia), manually, or as a no-permit harvest • capture plot geolocation with one tap (GeoJSON for the official EU system) • automatic harvest records under the active permit — measure as usual • simplified EUDR declaration in under 5 minutes — submit once, update only on change; export as text, CSV, PDF or GeoJSON • reference number vault (5-year retention) — for sawmills and traders too EUDR record-keeping is FREE all season; a paid upgrade unlocks exporting and submitting the declaration. Timberlog helps collect and store data; it is not legal advice and does not guarantee compliance. You submit the statement yourself in the official EU system. WHO IT'S FOR Log scalers, timber cruisers, sawmills, firewood sellers, chainsaw owners, and logging crews working with skidders and tractors. FREE + PRO The calculator is free. Pro removes all ads.

Verdict
The clearest difference is ratings volume: Calculator + at 10K against Timberlog's 34. Calculator + also leads on update cadence (every 4 days vs every 2 weeks). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Timberlog sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.6 for Calculator + against 4.7 for Timberlog. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 34, so its average is the more settled of the two. Written reviews split almost evenly too, at 85% and 86% positive.
Calculator + ships an update every 4 days, Timberlog every 2 weeks. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
