Track weight, appetite & water intake with auto trend charts. Rule-based alerts catch diabetes & kidney disease signs early.
Pet chronic illnesses often go unnoticed until symptoms are obvious -- but by then it's often too late.
Chronlo walks with you from prevention to early detection to long-term care, all in one app.
Daily logs that reveal changes
Track weight, appetite, water intake, and activity level. Automatic trend charts make subtle changes in your cat or dog impossible to miss.
Rule-based health alerts
Weight drop over 5% in 30 days, diabetes signal pattern (normal appetite but weight loss + increased water intake), CKD signal pattern (decreased appetite + weight loss + increased water intake) -- when conditions match, an alert card pops up automatically with specific recommendations.
Blood test photos, instantly understood
Photograph a blood test report and Chronlo automatically reads the numbers and turns them into trend charts, so you don't have to stare blankly at unfamiliar medical terms and numbers.
Chronic illness encyclopedia
Educational articles on CKD, diabetes, heart disease, joint degeneration, tumors and more, sourced from IRIS Kidney, Cornell Feline Health Center, AAHA and other professional veterinary resources.
Medication and vet visit reminders
Never miss a dose or an appointment again.
Vaccination records
Track injection date, site, and vaccine name, with reminders for site rotation.
Home heart monitoring
A 30-second sleeping respiratory rate counter using a real clinical home-monitoring method to catch early warning signs of heart disease.
Chronlo does not perform unvalidated AI image diagnosis -- all rule logic is based on verifiable veterinary information. We would rather do less than guess.
Catch it one step earlier, share one more chapter together.
