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.

Verdict

The call

The clearest difference is price: EE ToolKit at Free against Physics Formulas's $0.99. EE ToolKit also leads on review sentiment (90% vs 50%) and ratings volume (1.4K vs 1). Physics Formulas's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.7). On update cadence, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Physics Formulas holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: EE ToolKit has 1.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of EE ToolKit's written reviews are positive against 50% of Physics Formulas's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

EE ToolKit ships an update every 3 months, Physics Formulas every 4 months. The most recent releases landed on September 23, 2026 and September 13, 2026 respectively.
