One line per calf
Dam, sire, date, sex, calving ease, vigour, birth weight and notes on one row, the way the paper book lays it out. The same row carries weaning and loss later.
CERTALOT CALVING
The calving book you already keep, on your phone.
A calving book for Canadian cow-calf producers. One line per calf, working fully offline with no account and no signal. Your first 15 calves are on us.

WHAT IS IN THE BOOK
Works with no signal
The whole book is on your phone. No account, no signal, no login screen between you and the cow.
Tag bags that count themselves
Set the tag bag up once and the next number is already in the calf's record. Skipped and damaged tags are tracked, and the bag reconciles at the end.
Photos of the calf and its tags
Photograph the calf, the RFID tag and the drop tag. The tag number is read off the photo and shown for you to confirm. It is never filled in without you.
Groups and vaccinations
Sire groups build themselves from the sire you recorded. Record a group treatment once with product, lot, dose and route, and the withdrawal date is worked out for you.
A book per season
Each season is its own book, kept on the shelf and still readable years later. Export any season to CSV or PDF, and bring your cow list in from a CSV.
Gestation calculator, score legends and year letters are built in, like the inside cover of a paper book.
WHAT IT COSTS
