Let’s face it. The brain is complex, but it is extremely fascinating. To study the brain, you typically have to be a graduate student at a major university. But not any more! Backyard Brains enables everyone to be a neuroscientist! Coupled with our SpikerBox you can order at: http://backyardbrains.com this app allows you to view, hear, record and analyze actual neural signals. Both from individual neurons and muscles. Backyard Brains provides affordable neuroscience experiment kits for students of all ages to learn (hands-on) about electrophysiology. Now everyone from schoolchildren to grad students and every grade in between can experiment with similar tools used by real neuroscientists worldwide! By following a few simple steps, everyone can experience first-hand how the brain communicates with our senses, memories, hopes, and desires. Our iOS application includes both long continuous and threshold views, and once you have recorded your data, you can analyze the neural spike trains, measure reaction times, and calculate statistics just like professional neuroscientists! Do let us know us know about your experiments. Note: The application normally picks up input through the the iPhone's built-in microphone. If you want to plug directly into your SpikerBox, or any audio device, you need a custom male-to-male headphone cable (a normal one won't work), available from our website. It has to do with routing and filtering an output channel to an input channel.

About

Logic

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 call

Spike Recorder and Logic both sit at 3.4 stars, but that hides the real split: 62% of Spike Recorder's written reviews are positive against 21% of Logic's. Spike Recorder also leads on ads (none vs shown) and monetization model (free vs ad-supported). Logic's advantage is update cadence (every 5 weeks vs every 4 months). On price, rating, ratings volume and in-app purchases there is nothing between them.
