The short version

  • Only Herdwatch has a free tier, so it costs nothing to try first.
  • Each has a real cost: Herdwatch annual pricing amounts not displayed, calculated dynamically based on farm type and herd size; Teralytic the company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • They diverge on capability: Herdwatch covers Animal registry, Teralytic covers Wireless NPK sensing.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Herdwatch

  • Annual pricing amounts not displayed, calculated dynamically based on farm type and herd size
  • Free trial available but actual subscription costs vary by farm size
  • Pricing shown excluding VAT

Teralytic

  • The company is reported at around six employees, so if it stops trading the buried probes become inert hardware, which is the single biggest risk in a multi-year soil sensing deployment.
  • No current pricing is published and reported figures have moved between roughly 300 and 500 US dollars per probe per year, so a buyer cannot model the cost of a hundred-probe deployment without a quote.
  • The subscription is mandatory for the probe to report at all, so the up-front hardware payment buys nothing durable and a lapsed account means a field full of dead instruments.
  • In-field NPK sensing is scientifically contested and readings need interpretation against soil type and calibration, so agronomists will not treat the numbers as interchangeable with a lab test and many will insist on both.
  • Spatial coverage is the unsolved problem: a probe measures one point, soil varies over metres, and covering a field properly multiplies both the hardware and the annual subscription by the number of zones you care about.

Answered from the vendors’ own pages

Herdwatch: What pricing options are available for Herdwatch?

Herdwatch offers a 6-month promotional plan at $49 with full access to all Complete features and no long-term commitment. Pricing is customized based on your farm type and herd size, with both annual and monthly options available.

Source
Teralytic: Can I buy the probe without a subscription?

No. The probe reports through Teralytic’s network into its cloud, and without an active subscription it does not deliver data.

Herdwatch: Can I try Herdwatch before purchasing a subscription?

Yes. Herdwatch offers a free digital calving book to new registrants and allows users to try the app free before committing to a subscription, with full access to features during the trial period.

Source
Teralytic: Does it replace lab soil tests?

No. It gives continuous in-season trend data. Most agronomists will still want lab results for absolute nutrient values and for compliance records.

Herdwatch: What free features does Herdwatch provide?

Herdwatch provides a free subscription tier that includes a free digital calving book for tracking calving events. This free option allows basic record-keeping without requiring immediate payment.

Source
Teralytic: How much does it cost?

Teralytic does not publish current pricing. Reported figures have ranged from roughly 300 to 500 US dollars per probe per year including hardware and connectivity.

Teralytic: How many probes does a field need?

That depends on soil variability. One probe represents one point, so a field with several distinct soil zones needs one per zone to be meaningful.
