Price, ratings, monetisation and update history for both apps, side by side β with what reviewers say about each.
Smart Puncture
This app helps visualize angles and distances relative to gravity. It displays a line that rotates with your iPhone, changing background color when tilted. You can also draw circles to measure distances from the rotation center.
- Angle rotation with gravity reference
- Background color changes with tilt
- Draw circles for distance measurement
- Visualize lines with rotation

When you press βRotateβ after setting angle, your iPhone displays the line with respect to gravity. When your iPhone is tilted, background color will change. You can draw two circles around the center of rotation to know the distance.
EmboVol

EmboVol is a lightweight calculator for estimating coil packing densityβalso called the Volume Embolization Ratio (VER)βduring intracranial aneurysm coiling. Use it in three simple steps: Aneurysm: Enter aneurysm size (3 dimensions) or volume. Plan: Choose a coil system and target packing %, then get an estimated total coil length/volume from a simplified model. Procedure: Log each opened coil package and mark whether its coil was deployed. Running opened/deployed totals and grouped counts stay visible while EmboVol estimates achieved packing density, deployed coil volume, and residual volume. Key features β’ Aneurysm volume from 3 dimensions (ellipsoid approximation) or direct volume input β’ Coil volume from outer diameter (OD) and deployed length (cylindrical approximation) β’ Target packing slider with instant required-volume/length estimates β’ One-tap package logging with quick Repeat and Undo β’ Separate opened-package and deployed-coil counts β’ Editable coil catalog with visible source and provenance information β’ Save, restore, and QR transfer without patient identifiers β’ On-device only: no accounts, no tracking, no patient data collection Important EmboVol provides simplified estimates and is not validated clinical decision support. Always cross-check calculations, units, and device specifications against current IFU/product documentation and local protocols.

Verdict
The clearest difference is in-app purchases: Smart Puncture at none against EmboVol's 2. Smart Puncture also leads on iOS requirement (12.0 vs 17.0). EmboVol's advantage is update cadence (every 2 months vs every 9 months). On price, ads and device support there is nothing between them.
