- Adjust user interface handedness
- Select color themes
- Supports proton and carbon NMR data

NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have a short list of candidate impurities. NMR Solvent Peaks has support for searching both proton and carbon data, and references the widely-distributed 2010 Organometallics paper by Gregory Fulmer and coworkers and the 2016 OPRD paper by Gregory Whiteker and coworkers. Feature Highlights: - search for impurities based upon mode (proton/carbon), deuterated solvent, multiplicity, and ppm - select "show all" for ppm to see an alphabetical list of all impurities in the app's database - pick a color theme and adjust the user interface handedness

Verdict
The clearest difference is in-app purchases: NMR Solvent Peaks at none against MultiTimer's 4. NMR Solvent Peaks also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 79%). MultiTimer's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (16K vs 11). On price, ads, device support and iOS requirement there is nothing between them.
