App to predict ¹³C and ¹H NMR spectra: draw a structure to see its spectra. The accuracy (Mean Average Error) of the algorithm is about 1.5 ppm for ¹³C and 0.21 ppm for ¹H (RMSE = 2.8 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. The prediction algorithm is a combination of neural network and spheric codes based algorithms.
Logic

- Design logic gate networks
- Simulate network behavior
- Generate truth tables
- Minimize boolean expressions
- Create input-output waveforms
- Study boolean algebra theorems

The LogicGateDesign is a feature rich app designed by an engineer. This app allows the creative smart people like you to design, draw, analyse and simplify logic gate networks. You can draw logic gate networks and share it with others. You can generate truth table and find simplified/minimized boolean expression that represents the network. You can optimize and reverse engineer a boolean expression to draw a ladder logic diagram. It performs both forward engineering (boolean expression to logic circuit) and reverse engineering (logic circuit to boolean expression). There can be multiple groups of network and each group can have multiple outputs. Truth table is generated for all the outputs. You can simplify a boolean expression, and find the truth table and share it. Show truth table along with different types of boolean expression (simplified, Sum-of-products, Product-of-sums) The simplified expressions also gives you the number of gates required. You also get the alternate expressions for the same output with the gates required for that. You can generate a truth table, simplified boolean expression using input-output waveforms. You can generate a output waveforms, simplified boolean expression using truth table and input waveforms. You can generate a grey codes and grey code encoder wheel and share it. Do you have a truth table for your network and want to find the simplified/minimized boolean expression? This app has you covered. You can simulate your network by changing one input at a time or toggeling all inputs at once. This app generates beautiful diagrams (logic gate diagram or waveform diagram) that you can share with others or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There is also a page to help you study. This study tab teaches you some very important boolean algebra theorems. This is a perfect app for a creative smart individual like you. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

Verdict
The clearest difference is rating: All NMR at 5.0 against Logic's 3.6. All NMR also leads on monetization model (free vs ad-supported) and iOS requirement (12.0 vs 15.1). Logic's advantage is update cadence (every 5 weeks vs every 72 months) and device support. On price, ratings volume and in-app purchases there is nothing between them.
