This is the brand-new Electronics Engineering ToolKit PRO! The HIGHLY RATED and RECOMMENDED productivity app. Users say it is the BEST and MOST PRACTICAL Electronics App in the whole iTunes App Store. From an electronics enthusiast with a master's degree in Electronics Engineering. This App is for engineers, students and hobbyists and anyone interested in Electronics Engineering. The App gets CONSTANT and POWERFUL improvements! !!! This is a UNIVERSAL App - for iPhone and iPad !!! 100% PRO from the beginning without any In-App purchase! The EE ToolKit PRO is the preferred Electronics App at schools and universities. It is available through the Volume Purchase Program with a discount for educational institutions. Many students, teachers and professors have downloaded the App and are using it during their studies and career. WHAT OTHER USERS ARE SAYING: “Awesome app, constant and powerful improvements” This app was worth every penny I paid for it back when I bought it years ago. Since then, I’ve regularly used it at work and found it to be an excellent, quick tool to use. The most impressive aspect of this app are the constant and VERY impressive updates! Massive feature additions and very easy to use interface! The list of capabilities this app has makes it an amazing value for truly anyone involved in electronics. “Latest version makes this an exceptional tool” The EE Toolkit was always a very useful tool, but with the additions in the latest version it is truly an exceptional tool. The author is extremely diligent in managing bugs and improving the tool. “A superb app highly recommended” Fantastic application. Very useful. Always updated. Good developer. Lots of great bonus tools. Just love it. "Incredible useful, worth the money" I have had this app for a while now. Originally as an Electrical Engineering student I didnt really use it but once I was out in the field it became my bible. I definitely recommend to any engineering students/professionals alike. I also recommend buying the Pro version because it is definitely worth it. FEATURES OF THE EE TOOLKIT: Ω more than 160 electronic applications Ω amazingly great multi-functional keyboard Ω huge selection of color code tools and SMD code tools Ω audio scope and a frequency pitch detector Ω favorites page only for the tools that you have marked as favorite Ω full-featured frequency generator Ω extra large component reference section (incl. 7400 Series, PIC family, etc.) with the option to open pdf datasheets live or by e.g. iBooks Ω 555 Timer Tools with the most important application examples Ω extensive collection of Single Board Computers (more than 120 different boards!!!) Ω PCB trace impedance tools for several different structures Ω simple and quick unit conversion within the single calculators Ω fast on-the-fly conversions and calculations Ω real-time circuit simulations of the example circuits Ω support for preferred E series, sliders and min/max calculations Ω auto-save of all entries over several sessions Ω file manager to save and load individual calculations Ω built-in access to your iCloud Ω formula search tool with quick links to the tool which uses the formula Ω and many many more

About

DCircuit Lab

Design and simulate digital circuits with a comprehensive set of tools. Explore combinatorial and sequential logic, including gates, flip-flops, and custom components. Dynamic simulation with timing charts helps analyze circuit behavior.

Highlights
  • Combinatorial and sequential circuit simulation
  • Single-step and step-by-step simulation modes
  • Dynamic simulation with timing charts
  • Wide range of logic gates and flip-flops
  • Custom component creation via truth tables
  • Integrated video tutorials

Read full description

DCircuit Lab is a tool to simulate combinatorial and sequential digital circuits. Circuits can be simulated in two ways: 1) one single step: all the outputs values are evaluated at the same time 2) step by step: outputs and gates are evaluated one step a time If circuit contains clock inputs, its simulation is dynamic. This means that outputs change accordingly to the clocks. During this dynamic simulation, user can change inputs values to study the circuit behavior which is also provided via a timing chart. Circuits are built using basic components, gates and flip-flops: * inputs (three state: 1, 0, X - undefined) * outputs * wires * NOT, AND, NAND, OR, NOR, XOR gates with any number of inputs * Flip-flop RS, JK, T, D (Positive or Negative Edge Triggered and with Set and Reset Inputs) * Multiplexers with any number of inputs * Demultiplexers with any number of outputs * Fully configurable Clocks * Custom Components defined by their truth table * BCD to 7 Segments Display Decoder * 7 Segments Display Some video tutorials are available directly from the application to learn how to use it.

Verdict

The call

The clearest difference is review sentiment: EE ToolKit PRO at 90% against DCircuit Lab's 11%. EE ToolKit PRO also leads on rating (4.9 vs 3.0) and ratings volume (293 vs 3). DCircuit Lab's advantage is price ($3.99 vs $9.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
