This is the brand-new Electronics Engineering ToolKit! The HIGHLY RATED and RECOMMENDED productivity app. Users say it is the BEST and MOST PRACTICAL Electronics App in the whole 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 !!! With In-App upgrade to PRO. If you don't like In-App purchases, you can also download the PRO version (red icon with PRO text) which is full PRO from the beginning without any In-App purchase. 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

Read full description

bitGateLab Digital is a digital electronics lab on your PC, phone or tablet: design a circuit with logic gates, watch it run live, get its truth table and Karnaugh map, check the timing diagram and build it on a 3D breadboard with step-by-step wiring. No account needed. The free version needs internet for ads; with Premium it works offline. DESIGN AND SIMULATE • AND, OR, NOT, NAND, NOR, XOR, XNOR and buffer gates; inputs, switches, push buttons, DIP banks, LEDs, LED strips and bar graphs, 7- and 16-segment displays, buzzer. • Sequential logic: D, T, JK and SR flip-flops, clock, crystal, counters, 555 timer, word generator, serial monitor. • Components: multiplexers, buses, ROM and RAM, H-bridge, motor, optocoupler, registers. • Group any part of the circuit into a reusable block with its own pins. • Undo and redo, copy and paste, named and colored wires, grid and automatic fit. TRUTH TABLE AND KARNAUGH • Type a boolean equation or fill in the truth table and turn it into a circuit with one tap. • Karnaugh maps from 2 to 8 variables, with groupings, canonical form, minterms or maxterms. • Step-by-step simplification naming each law applied, NAND form and Verilog export. • From the circuit back to the truth table or the Karnaugh map. TIMING DIAGRAM • Every input combination as a binary counter, with the hex value of each cycle. • A and B probes to measure intervals, X and Z levels, slopes and propagation delay per logic family (TTL, CMOS...). • Export to PDF. 3D BREADBOARD • Your circuit becomes a real build on its own: 74-series chips, resistors, LEDs, switches and wires on one or more breadboards. • Step-by-step guide hole by hole (for example 44i → 12i), bill of materials and net list. • Move chips, LEDs and switches where you like, recolor wires, isolate a net or a single wire, undo and redo. • Labels on every input and LED, free rotation, zoom and image capture. MICROCONTROLLERS AND PROGRAMMABLE LOGIC • MCU51 (8051-compatible) and MCU14 (14-bit): program in C or assembly, assemble and single-step with registers, ports, timers, interrupts and UART. • 16V8, 20V8 and 22V10 PLDs: equations, fuse map and JEDEC file. • Ready-made examples: counters, blinkers, traffic lights, serial communication and more. SHARE AND SAVE • Save your circuits with version history; share them as a file, a link or a QR code. • Export images as SVG, PNG, JPEG, WebP or PDF, and code as Verilog. • Number systems calculator, two's complement and binary operations with flags. FOR LEARNING AND TEACHING • Reference of boolean algebra laws and theorems. • State table and state diagram of your sequential circuits. • Large-button interface, comfortable on PCs, phones and tablets; light and dark themes. • 45 languages: Spanish, English, Chinese, Arabic, Hindi, Portuguese, Japanese, Korean, French, German, Russian and many more. PRIVACY No account and no cloud: your circuits are stored only on your device. Something not working? Settings → Report a problem sends your message with the app version, device model and a technical log, with no personal data. The free version shows ads; Premium removes them.

Verdict

The call

The clearest difference is ads: EE ToolKit at none against Digital Simulator bitGateLab's shown. EE ToolKit also leads on iOS requirement (12.0 vs 15.0). Digital Simulator bitGateLab's advantage is update cadence (every 3 days vs every 3 months). On price, in-app purchases and device support there is nothing between them.
