Read full descriptionHide full description
PHVD is a reference and educational tool for neonatal clinicians working with post-haemorrhagic ventricular dilatation in preterm infants. Enter serial cranial ultrasound measurements โ ventricular index, anterior horn width and thalamo-occipital distance โ alongside post-menstrual age, and see them plotted against published reference curves. WHAT IT DOES โข Records serial measurements across post-menstrual age โข Plots them against published reference curves โข Shows the trend across a series of scans โข Keeps everything on your device WHAT IT DOES NOT DO PHVD does not diagnose, does not recommend treatment, and does not replace clinical assessment, imaging review, or your local protocol. It is a reference aid for qualified healthcare professionals. Every output must be independently verified against the source images and your unit's guideline. PRIVACY PHVD collects no personal data. Nothing you enter leaves your device. There is no account, no login, and no analytics. A full disclaimer is presented on first launch and must be accepted before the app can be used. Reference framework adapted from El-Dib et al. (2020); reference curve from Brouwer et al. (2012).

Verdict
The clearest difference is update cadence: PHVD at fortnightly against CPS's every 12 months. CPS's advantage is iOS requirement (11.0 vs 13.0). On price, ads, in-app purchases and device support there is nothing between them.
