Arboreal Forest — Forest Inventory App The fastest and most accurate way to measure your forest — straight from your iPhone. Two professional plot methods in one app: fixed-area plots and prism plots. No caliper, no relascope, no paper forms. Used by professional foresters, forest engineers, and land managers across Europe and the Americas. Validated in peer-reviewed research and awarded best mobile app for forest measurements. Two ways to measure your forest FIXED-AREA PLOTS Walk the plot and measure every tree with AR and LiDAR. Diameter, height and species are recorded tree by tree, and plot results are compiled instantly. - Diameter and basal area - Trees per hectare - Stand volume - Tree height - Tree species PRISM PLOTS — NEW Variable radius plots (angle-count sampling), the standard method for timber cruising in North America. The iPhone's telephoto camera works as a precise digital prism: stand at plot center, turn around the phone, and the app shows which trees are in. - Choose your basal area factor (BAF) - Big BAF sampling: count with one BAF, measure a subsample with a larger one — and get stand volume - [Automatic slope correction] - Basal area and volume on the spot — no tally sheet 2.5x faster than traditional methods Arboreal Forest replaces caliper, tape, relascope and prism with AR, LiDAR and camera technology. You get compiled results immediately — no office work needed afterwards. Sub-centimeter accuracy Diameter measurements validated against manual measurements in a 2024 scientific study show sub-centimeter accuracy.

Verdict
The clearest difference is rating: Arboreal Forest at 4.2 against Timber Calculator Plus's 1.0. Arboreal Forest also leads on update cadence (every 6 days vs every 6 months) and ratings volume (5 vs 1). Timber Calculator Plus's advantage is review sentiment (67% vs 25%) and iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and monetization model 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. Arboreal Forest sells 4 in-app purchases, starting at $8.99 per 7 days and Timber Calculator Plus sells 2 in-app purchases, starting at $1.19 per month. Whichever you choose, the download price is not the number that matters.
Arboreal Forest holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: Arboreal Forest has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of Arboreal Forest's written reviews are positive against 67% of Timber Calculator Plus's, so the app with the better star average is not the one people write more warmly about.
Arboreal Forest ships an update every 6 days, Timber Calculator Plus every 6 months. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
