App to predict 13C and 1H NMR spectra: draw a structure to see its spectra. The accuracy of the algorithm is about 1.9 ppm for 13C and 0.21 ppm for 1H (RMSD=3.4 and 0.31 ppm correspondingly).

- Instantly re-calculate spectra while changing structure;
- Predicted spectra stored in iCloud and synchronised among all iOS devices and Mac version;
- Email PDF report;
- Zoom in spectrum;
- Zoom in structure (important for iPhone users);
- Option to display chemical shift values on structure;
- Simple clean interface.
