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

Pass circuits. 3 minutes a day. Ohmie teaches electronics the way you'd learn a language: short, game-like lessons you actually solve, not paragraphs you skim. Lessons are read aloud, so your eyes stay on the circuit. Everything below is part of Ohmie Pro, an auto-renewing subscription. Details are in OHMIE PRO SUBSCRIPTION at the end. REAL PRACTICE • Live circuit sims: stack battery cells, dim an LED, watch current respond to resistance • Build schematics by dragging real components into place • Decode resistor color bands, spot the broken circuit, order the steps • Miss a question? It comes back in Practice until it sticks. That's the method, not a penalty. LEARN THE FULL PATH • Electronics: charge, current, voltage, Ohm's law, series and parallel, capacitors, power, analog, then transistors, logic gates and an 8-bit computer you can run, pause and step through • Physics: charge, electric fields, Gauss's law, potential, capacitors, circuits, magnetism and induction • Embedded systems: GPIO, timers, PWM, ADC, interrupts, serial protocols, build a device • Robotics: sensors, motors, PID control, build a line-following racer • PCB design: schematics, layout, routing, production • Programming: Python, and C++ for Arduino MOMENTUM THAT FORGIVES XP, streaks, daily quests, 28 badges to earn, skins to unlock, leaderboards, and a mascot named Ohmie who reacts to every answer and is on your side. Streaks are forgiving. Life happens. Stuck? Ask Ohmie and get a hint in plain words. No ads. Learn in English, Spanish or German. Sign in to keep your progress across devices. OHMIE PRO SUBSCRIPTION Ohmie is free to download. The lessons, practice, circuit sims, Ask Ohmie and everything else described above require an Ohmie Pro subscription, billed monthly or yearly. The yearly plan starts with a free trial for eligible new subscribers. Prices are shown in the app before you buy. Payment is charged to your Apple Account. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings.

Verdict

The call

EE ToolKit and Ohmie both sit at 4.7 stars, but that hides the real split: 90% of EE ToolKit's written reviews are positive against 48% of Ohmie's. EE ToolKit also leads on ads (none vs shown) and ratings volume (1.4K vs 372). Ohmie's advantage is update cadence (every 3 days vs every 3 months) and chart position (#80 vs unranked). On price, rating, in-app purchases and monetization model there is nothing between them.
