EarthOptics is a soil data and services platform specializing in measuring and quantifying soil attributes. We provide an integrated suite of services, including soil sampling, in-field proximal sensing, and laboratory testing, which underpin our core soil management data products. Our soil sampling app enables field professionals to successfully execute field sampling protocols according to a variety of technical specifications.
more • Introduced a multi-notes option so you and other samplers are no longer limited to a single note in sampling plans and agronomy samples (soil core and carbon samples coming soon).
• Redesigned map layers and tools menus with a new on-map field legend for easier navigation.
• Added an in-app Airplane Mode so you can work offline in the app itself but stay connected in other apps.
• Fixed photo capture and upload issues that could cause lag, data loss, or stuck retries.
• Resolved map marker rendering glitches and unintended taps during zoom.
• Added ESM sampling guidance including depth reminders, SOP info, and probe-type color coding.
• Improved overall stability for equipment data, form submission, and sign-in sessions.
13.4.0 23 Jun
- Clearer sample labels (external-lab plans). For sampling plans that use sample-specific barcodes, each sample and soil-core segment now shows its printed label ID prominently, with a reminder before you scan so you always grab the right label.
- Smarter QR scanning (external-lab plans). On these labeled plans, the app accepts only the correct printed label and tells you exactly which label to scan if there's a mismatch — with a manual-entry fallback that lists everything you need to write on the bag.
- Plan documents. View sample-label and manifest PDFs for your plans, and export them to email, Files, or other apps via the share sheet.
- Sync progress banner. A new banner shows when your offline work is uploading, what's currently syncing, and when the upload is complete.
- Field contacts. Quickly find and call or email the point of contact for a field.
- Update reminders. A gentle banner lets you know when a newer version of the app is available.
- Reliability improvements. Hardened offline data handling so completed work is reliably saved and synced, plus a range of stability fixes.

- Fixed a bug where scanning one QR could mark a multi-split core as done before it really was.
- Cleaner photo upload status — no more "pending" message after photos have already uploaded.
- Field options menu reliability and clarity improvements, including reasons when an option is unavailable.

v11.10.1 6 Mar
- Move samples: When you're unable to sample a point, you can now reposition it using several tools: offset by 10m in any direction (N/E/S/W), manually click to reposition it on the map, snap it to your current GPS location, or select an alternate pre-planned point (if available).
- Restore original point: After moving a sample, you can restore it to its original location at any time.
- Works for all non-bio sample types, with and without soil cores.
v11.10.0 6 Mar
