The app
What does Workup do?
Workup runs peer-reviewed cardiac measurement (VHS/VLAS) from a camera capture of a canine right lateral radiograph, predicts feline urine specific gravity from bloodwork (a pilot), includes a 326-drug offline dose calculator, and bundles nine clinical calculators — CRI, IV potassium, fluid therapy, chemo BSA, transfusion, RER, HHS, the AHS heartworm protocol, and Pro-Sal — plus IRIS CKD staging and a breed VHS reference. Results can be exported as client-friendly PDF handouts.
Can I get Workup right now?
Yes — Workup is available now on iOS and Android. Install it from the App Store or Google Play. Every feature is included in a 30-day free trial, and after that you pick a plan; every plan is the whole app, with nothing held back for a higher tier.
Can I use Workup offline?
The nine clinical calculators, the 326-drug dose calculator and the clinical references work fully offline — the drug catalog ships bundled in the app. VHS/VLAS measurement and USG predictions run on cloud inference and require a network connection. If you lose connectivity mid-scan the app surfaces an offline banner and lets you retry when reconnected.

The measurement
How accurate is the VHS/VLAS measurement?
The algorithm was validated against one trained human observer across 1,058 client-owned dogs of 80 breeds, and published in PLOS ONE (2026, doi:10.1371/journal.pone.0337679). VHS agreement was Pearson r = 0.917 with a mean bias of 0.002 vertebrae and limits of agreement of −0.85 to 0.85; VLAS was r = 0.873, bias 0.007, limits −0.44 to 0.46. The limits of agreement are the number to carry into a borderline call. The comparison was against a single trained observer — not a panel, not board-certified radiologists, and not echocardiography, which the paper names as future work.
How do I capture the radiograph — do I photograph the monitor?
Yes. You photograph the radiograph with the phone camera, from your viewer or a lightbox, and the app detects the landmarks from that capture. There is no PACS integration and nothing to install on the practice network. Every measurement comes back with a quality tier of OPTIMAL, GOOD or REVIEW, which is how the app tells you the capture was not good enough to rely on.
What if the landmarks land in the wrong place?
You move them. The landmarks are editable, and the score recalculates from where you put them — that is the veterinarian-in-the-loop part, and it is why the number is defensible in a record. A REVIEW tier usually means dragging a landmark rather than re-shooting the radiograph.
What images does it work on?
Canine right lateral radiographs, of good quality. That is the scope the published validation covers, so it is the scope the app claims: not other views, not other species, and not poor-quality captures.
What breeds are supported for VHS reference?
20 named breeds with published normal VHS ranges, plus a general canine range as the fallback — 21 rows in total. A breed outside those 20 is measured against the general canine range, not a range of its own. The result screen shows whether the measured VHS falls within, above, or below whichever range applies. The complete list is in the app, under the clinical references.
The USG pilot
Is the USG Predictor ready for clinical decisions?
No. Feline USG screening is a pilot. Use it as a screening prompt to flag cats that need urinalysis, never as a replacement for one. On its most recent temporal holdout (model v1.6, 248 cases) it caught 92% of cats with impaired concentrating ability at a specificity of 60%, AUC-ROC 0.86 — so roughly 4 in every 10 cats with adequate concentration are still flagged for a urinalysis they did not need. The model report labels the tool for investigational and research use, states it is not validated for clinical deployment, and records no external validation and no prospective outcome data. The score is an uncalibrated ranking signal, not a probability.
What bloodwork values does the USG Predictor need?
Five: patient age in years, BUN, creatinine, hemoglobin, and absolute lymphocytes. The model is trained on feline data only and is intended for cats. The result shows how much each input pushed the prediction toward higher or lower USG, so you can sanity-check the model against the clinical picture.
Your data
Does Workup store my radiographs?
Images used for VHS/VLAS scans are sent to our inference backend for processing and are retained for up to 24 hours, after which they are automatically deleted. The 24-hour window lets us investigate scan-quality issues if you flag a result. Scan results — score, landmarks, metadata — are stored on-device and optionally in your account for history review.
Why does Workup need camera and photo permissions?
Camera access is required for live radiograph capture. Photo library access is required only if you want to analyze an existing radiograph image instead of capturing one live. Both can be revoked at any time in your device settings; the rest of the app still works.
Plans
How much does Workup cost?
A 30-day free trial with full access to every feature, then $2.99 per week, $9.99 per month, or $99.99 per year (about $8.33 a month). Note that the weekly plan is the most expensive per month, not the cheapest — it buys the shortest commitment. Your trial begins when you start the subscription in the app, and there is no charge until day 31. Cancel any time in your App Store or Google Play subscription settings.
Do you offer team or enterprise pricing?
Yes, and it is priced to your group rather than published as a seat price. What ships today: your organization is billed as one Stripe subscription instead of a reimbursement claim from every DVM, and access runs off a member list of work emails that you control — a DVM enters their email in the app, gets a code, and is covered by the organization’s plan. Every DVM on the roster gets the whole app; there is no separate enterprise tier and nothing is feature-gated. Still being built, and named as such: cross-site utilization and agreement reporting, single sign-on against your own identity provider with deactivation that follows an offboarding, a master services agreement beyond our published terms, and analysis attached to the imaging study itself.
