A super handy way to save time on all those lengthy Science class formulas! And of course, it has Dark Mode for those late night study sessions! Now Supports Calculating: - Wavelength, Frequency, and Velocity - Nuclear Bomb Blast Radius (with a Built in Simulator) - Half Life Computation - Protons & Neutrons (plus Atomic Mass) - Volume and Surface Area of Objects - Number to Logarithm Equation - with more on the way! This project was developed by an aspiring high school student as a mini project for Physics class, hope you like it! And feel free to contact me if you find any bugs!

Verdict
The clearest difference is update cadence: Science Calc at every 5 days against 试题库's every 3 months. Science Calc also leads on iOS requirement (15.0 vs 17). On price, ads, in-app purchases and device support there is nothing between them.
