For beef suckler farms · in Estonia now
Record calvings, weights and pregnancy results on your phone or a printed Kari sheet. Prepare data for EPJ and PRIA submissions, and compare animals for herd selection and breeding.
Kari is still in testing. In Estonia it is free through 31 May 2027, in exchange for your feedback.
In Estonia, you start with access to your herd in EPJ's Liisu or e-PRIA. Elsewhere, tell us your country. No payment card.


At the crush, in the barn and on the paddock: weight, condition, temperament, calving and a note, one animal at a time. It works without signal and sends the records when signal comes back.


A bigger screen makes comparing easier: weight curves, animal lists, animals of the same group side by side, which cows to keep and which bull to use. The same records that went in on the phone, which you can also look at there.
Screens from the demo herd.
Six questions from the farm year. Kari answers them from your own records, with the reason and the next step. The decision stays with you.
See estimated calving dates and print a barn sheet.
Kari uses bull dates and pregnancy-check results to estimate calving dates. See the expected order and cows whose information is incomplete. Record each calving on your phone or a printed sheet.
Prepare an animal list for weighing, condition scoring and pregnancy checks.
Prepare one list of animals to weigh, condition-score or pregnancy-check. Enter the results on your phone or a printed sheet. Kari shows which results are still missing.
See events awaiting submission to EPJ or PRIA.
Kari lists events awaiting submission and their deadlines. Download prepared files for supported events, review them and submit them in the relevant system. Direct EPJ and PRIA connections are planned.
Review calving, pregnancy, calf-growth and temperament records together.
Review each animal's calving history, pregnancy results, calf growth and temperament. Kari shows the recorded reason for a flag and identifies missing information. You decide which animals to keep.
Compare bulls using your herd results and EPJ breeding values.
Use your herd results to identify breeding priorities. Compare the relevant EPJ breeding values and each bull's relationship to your females.
Compare pregnancy, calving and weaning results across years.
Compare pregnancy rate, calving in the first three weeks and kilograms weaned per cow exposed to the bull. Kari also shows missing source records.
Fits the way you work
Print a Kari sheet and fill it in while working with the animals. Photograph it, check the recognised entries and confirm before saving. You can also enter results directly on your phone.




The sheet contains the same animals and fields as the app. After you photograph it, Kari shows the recognised entries. Correct any mistakes before confirming. Confirmed results are added to the relevant animals' records.

Built from farm work
Kari comes out of years of working suckler farms: the practical work at the crush, in the barn and on the paddock, joined to clear decision rules and a breeding philosophy built around the cow.
In the app, Kari brings each farm's records together: weights, calvings, condition, behaviour and the vet's checks on one animal's page, and shows why an animal needs attention and which records are missing. It is used every day on a working herd.
Kari is made by Herdloop. Herdloop is looking for a co-founder.
In Estonia, access to your herd's records in EPJ's Liisu or e-PRIA, and an e-mail address. Kari works only with Estonia's systems for now; elsewhere, tell us your country. A guide takes you through set-up step by step: bringing in the herd, inviting your team and installing the app on the phone.
Sign in to your Liisu account and run Kari's bookmark there, as the setup guide shows: your animals come in with their parents, calvings and weighings. If the herd is not in Liisu, the animals come from the e-PRIA register list. Then check that the animal list is correct.
Kari is in testing. You can use it free through 31 May 2027. We ask you to report errors and anything that is difficult to use. You can send feedback from the app.
You choose whether to continue. No payment card is required and there is no automatic charge. The proposed prices, which may still change, are shown below; final pricing will be published before the free period ends. Terms for the test
| Herd size | Proposed annual price |
|---|---|
| Up to 10 cows | Free |
| 50 cows | €270 + VAT |
| 150 cows | €420 + VAT |

The work on a suckler farm is much the same everywhere: calving, weighing, the pregnancy check, the walk through the cows. What changes from country to country are the registers, their files and deadlines, and the language. Kari takes on one country at a time, with its rules built in.
