Kernel

Everyone counts. Kernel measures. Kernel is the first corn yield app to measure kernel size — not just count kernels. Two photos, on your phone, no signal needed. Free. HOW AN ESTIMATE WORKS 1. COUNT THE KERNELS — Photograph the whole ear. Kernel traces every row: kernels per row, rows per ear. 2. MEASURE THE SIZE — Snap the ear in half and photograph the cut face. Kernels per bushel is measured, not assumed. 3. ESTIMATE YIELD — Bushels per acre at 15.5% moisture, on the spot. The flow is faster than the hand count it replaces. IT WORKS AT THE FIELD EDGE Everything runs on the phone. Three bundled neural-network models ride along in the app, photos and estimates are stored on the device, and the whole flow works with no signal at all. EVERY NUMBER IS EDITABLE Kernel shows its work. Every measurement — kernels per row, rows, kernel depth, kernels per bushel — can be corrected by hand, and the edits stick. An estimate holds as many ears as you want to sample, reported as the average of the per-ear yields. EVERY EAR ON THE MAP Estimates auto-save, are named by GPS location, and are pinned on a map — searchable by field, hybrid, date, notes or location. Export selected estimates to CSV. Deleted estimates are restorable for 30 days. FREE, WITH OPTIONAL BACKUP No subscription. No account needed to estimate. Sign in with Google, Apple, or email only if you want your estimates backed up and restored to a new phone. Not tied to any seed brand. Built by Mark Gee of Gee LLC, who has worked in agriculture his whole life: "So much of the yield story is told by kernel size, and we're the first app to help farmers measure that." An estimate is a sample, not a measurement of your harvest.

Verdict
The clearest difference is in-app purchases: Kernel at none against PDF Calendar's 3. PDF Calendar's advantage is iOS requirement (13.0 vs 15.1). On price, ads and device support there is nothing between them.
