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!

Get convenient access to photonics calculators, equations, and other information and resources when you download this free app! This application is being continually updated to offer new types of resources, as well as to expand existing categories, so be sure to check for updates. The current version of the app includes a collection of calculators that engineers and technicians at Thorlabs Lens Systems and elsewhere have used on the floor for over 15 years. Each calculator page includes the equations used in the calculations, as well as usage notes and information about assumptions included in the equations. Additional resources include brief summaries of ray tracing, lens theory, Snell’s Law, manufacturing tolerances, and evaluation of system resolution using the modulation transfer function (MTF). History Thorlabs Toolkit builds on the excellent foundation provided by the JML Optical Calculator. When JML Optical joined Thorlabs’ family as Thorlabs Lens Systems, it provided a wonderful opportunity to expand the app to share knowledge collected from across all of Thorlabs.

Verdict
The clearest difference is update cadence: Science Calc at every 5 days against Thorlabs Toolkit's every 4 months. Thorlabs Toolkit's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
