Pocket MRS vs Dirac equation
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Pocket MRS
This app provides a quick reference and educational tool for in vivo magnetic resonance spectroscopy (MRS). It offers simulated human brain spectra and analysis, allowing users to visualize the impact of experimental conditions on spectral appearance.
- Simulated human brain spectra
- Detailed spectral analysis
- Manipulation of echo time
- Visualization of experimental conditions
- Quick digital reference
- Educational tool for MRS

Pocket MRS was designed to be a fast and versatile electronic reference and educational tool for students, medical professionals, researchers and anybody else engaged in the field of in vivo magnetic resonance spectroscopy (MRS). Pocket MRS is a mobile application that offers simple and easy access to simulated spectra from the human brain and its detailed analysis. Spectra available from 0 to 300 ms TE were obtained using realistic quantum mechanical density operator simulations, and then scaled using known concentration, T1 and T2 values across 19 different metabolites and the sum of 10 macromolecules. Spectra can be manipulated with respect to echo time, magnetic field quality and noise levels, providing quick and convenient visualization of the impact of typical experimental conditions on spectral appearance. The app can be a quick digital reference and valuable help for the MRS community when desktop computers and extended MRS software tools are not available.

Verdict
The clearest difference is iOS requirement: Pocket MRS at 14.2 against Dirac equation's 17. On price, ads, in-app purchases and device support there is nothing between them.
