NMR Tutor vs MathNotes
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
NMR Tutor
Explore NMR data acquisition and signal processing with interactive simulations. Adjust parameters like noise, apodization, and phase to observe immediate effects on FID and spectra. Learn about common artifacts and advanced concepts like spin-spin coupling.
- Interactive FID and spectra simulations
- Adjustable peak positions and decay
- Noise and apodization control
- Zero filling and phase correction
- Simulate acquisition artifacts
- Explore spin-spin coupling

NMR Tutor is an interactive introduction to NMR data acquisition and signal processing. Use simulated free induction decays (FIDs) and spectra to explore how time-domain NMR signals become frequency-domain spectra. Adjust peak positions, decay, noise, apodization, zero filling, phase behavior, and common acquisition artifacts, then see the effect immediately in the FID and final spectrum. The app displays real and imaginary FID channels before and after processing, together with the resulting spectrum after Fourier transformation. A live signal-to-noise (S/N) measurement updates as you adjust noise, scan averaging, apodization, FID artifacts, and shimming, making processing tradeoffs easy to compare. Apply zero filling to see how digital interpolation changes the appearance of the spectrum without adding new measured data. You can also introduce common receiver or acquisition faults into the FID and observe the artifacts that appear after processing. As an advanced example, add spin-spin coupling to create an AB coupling pattern, then move the peaks or change the coupling strength to compare AB behavior with an AX spin system. Charts retain every data point and support pan, zoom, phase-pivot dragging, graph audio, sharing and export, and external displays. Optimized Metal and Accelerate processing keeps high-resolution chart and shimming interactions responsive. Adaptive layouts and larger accessibility text make the workspace easier to use on iPhone, iPad, and Mac. Open one-dimensional JEOL, Bruker and Varian FID datasets directly. Inspect the acquired real and imaginary channels, then apply apodization, zero filling, first-point scaling, and zero- and first-order phase correction to your own data.

Verdict
The clearest difference is in-app purchases: NMR Tutor at none against MathNotes's 1. NMR Tutor also leads on ads (none vs shown). MathNotes's advantage is iOS requirement (13.0 vs 17.6). On price, rating, ratings volume and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MathNotes sells 1 one-off in-app purchase. NMR Tutor asks for nothing beyond the download.
