App to predict 1H NMR spectrum: draw a structure to see its spectrum. The accuracy of the algorithm is about 0.21 ppm (RMSD=0.31 ppm) obtained on a large independent dataset.

- Instantly re-calculate the spectrum while changing the structure;
- Email PDF report;
- Zoom in spectrum;
- Zoom in structure (important for iPhone users);
- Option to display chemical shift values on structure;
- Simple clean interface.
