## What is Luzardo?

Luzardo is herd management that fits in your pocket. Track every animal's health, weight, costs, and history from your phone, online or out where there's no signal.

Every animal gets a Cow Passport: its identity, lineage, traits, and key stats in one place. Need a weight? Take a few photos and Luzardo estimates it in seconds, up to 94% accurate on supported breeds, with more breeds in active development. No scale, no chute, no stress.

What you can do with Luzardo:

Cow Passport: a full digital record for every animal, from ID and lineage to breed traits and stats.
Timeline: every birth, move, vaccination, illness, and sale for an animal, in date order.
Photo weight estimation: on-device AI weighs cattle from a few photos, up to 94% accurate on supported breeds.
Vaccination and illness tracking: log treatments and outcomes so each animal has a clear health record.
Cost tracking: record purchase price and ongoing costs, and see the running total per head.
Breeding tools: log artificial insemination events and pregnancy checks.
Pen management: group cattle into pens and see average weekly gain and health by pen.
Batch updates: change several animals at once instead of one at a time.
National and Universal ID: keep your National ID and add a cross-ranch Universal ID, so animals stay identifiable anywhere.
Data export: email yourself your herd data whenever you need it.
Works offline: keep working with no cell service, and everything syncs when you reconnect.
Multiple ranches and teams: manage more than one ranch and invite your team.
English and Spanish: fully available in both.

### 5/5 — Useful for tracking and weighing cattle

*2026-07-23*

Makes it very easy to weigh and track the cows on my ranch. It also has AI based weight estimation using photos

### 5/5 — Great Resource

*2026-05-14*

The app is very user friendly overall. It’s easy to add new cattle and their information to my account. The features included are useful and it’s very quick and easy to customize my dashboard with the most relevant information needed.

### 1/5 — Useless

*2026-05-06*

Approximately a 55-60 lb newborn calf is estimated between 350 - 500 lbs.  pictures uploaded were carefully taken following the detailed instructions.

**Developer response:** Thank you for trying Luzardo and for taking the time to leave feedback. We're sorry the weight estimate was so far off for your calf.

You're right to be frustrated. Our current model was trained on adult cattle and does not produce accurate results for calves. We should have been clearer about this limitation in the app, and we're updating the app description to reflect that weight estimation works best on adult cattle of supported breeds.

We're actively working to expand the breeds and age ranges our model handles well. In the meantime, we've updated the app so that weight estimation is available through our data partner program, which helps us collect the feedback we need to improve accuracy across more animals.

If you're interested in working with us as a data partner, that would give you access to weight estimation and help us improve accuracy for Beefmaster cattle specifically. Please reach out at info@luzardo.tech. We'd genuinely value your input.
