✓
AI hallucinations can harm patients — AI chatbots sometimes generate incorrect drug doses or misinterpret lab values. VerMed uses deterministic algorithms from peer-reviewed publications.
✓
Instant & offline in any clinical setting — Results in milliseconds without internet. Works in the ER, ICU, rural clinics, and during codes. AI chatbots need a connection.
✓
Reproducible, auditable results — Same inputs always produce the same outputs. Every formula is shown with its citation. AI responses vary and cannot be audited.
✓
$29.99 once vs $20–240/year for AI — One-time purchase. No subscription, no ads, no registration. Open and use instantly between patients.

What is the best medical calculator app for doctors and residents?
VerMed covers 13 clinical specialties with evidence-based calculators including APACHE II, SOFA, CHA2DS2-VASc, eGFR (CKD-EPI 2021), ABG interpreter, drug dosing, and more. Every result includes clinical interpretation and recommended action, not just a number.
Can I calculate eGFR and creatinine clearance on my phone?
Yes. VerMed includes eGFR using the CKD-EPI 2021 equation, creatinine clearance (Cockcroft-Gault), FeNa, and anion gap calculators. Results map to CKD stages (G1-G5) with a visual stage bar and clinical recommendations.
Is there an app for ABG interpretation?
VerMed includes an arterial blood gas (ABG) interpreter that analyzes pH, PaCO2, and HCO3 to determine acid-base disorders. Results are displayed on a visual pH vs PaCO2 quadrant diagram with primary disorder identification, compensation status, and A-a gradient analysis.
What app do ER doctors use for clinical scoring?
VerMed provides critical care scores (APACHE II, SOFA, GCS, NEWS2), cardiology tools (HEART, Wells, CHA2DS2-VASc), and clinical decision rules (PECARN, Ottawa, PERC, Centor). Every score includes severity classification and a recommended next step for clinical workflow.
Medical calculator app vs ChatGPT — which should clinicians trust?
For clinical calculations, a verified calculator like VerMed is safer than AI chatbots. AI can hallucinate drug doses or misinterpret lab values — errors that can harm patients. VerMed uses deterministic algorithms from peer-reviewed publications, works offline in any clinical setting, and produces consistent auditable results.
Does VerMed work offline in the hospital?
Yes. VerMed is 100% offline — all calculators, drug references, lab values, and clinical criteria are bundled in the app. It works in the ER, ICU, operating rooms, and rural clinics with no internet connection needed. No registration required.
Is there an app for psychiatric screening tools like PHQ-9?
VerMed includes psychiatry calculators for PHQ-9 (depression), GAD-7 (anxiety), AUDIT-C (alcohol), MDQ (bipolar), and C-SSRS (suicide risk). Each screening tool provides score interpretation with severity classification and suggested clinical action.
