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.

Verdict
The clearest difference is price: Circuit Planner at $2.99 against EE ToolKit PRO's $9.99. Circuit Planner also leads on update cadence (every 2 weeks vs every 3 months). EE ToolKit PRO's advantage is review sentiment (90% vs 60%) and iOS requirement (12.0 vs 15). On ads, in-app purchases, monetization model and device support there is nothing between them.
