Free iOS App: +ION- (Science – polyatomic ions)

Written by Nathan Smith on . Posted in iOS Apps, Mobile Apps, STEM and STEAM

REVIEW:  "It took me a couple seconds to figure out I had to scroll down to see the formula for the given name or vice versa; no tapping or anything. Other than that, it's does exactly what it says: saves you time from making flash cards! I've only used it for about 20 minutes so far, but I haven't had any glitches!"

+ION- was made for you so you can spend your time learning polyatomic ions instead of making flashcards. Plain, simple, and FREE!

** Scroll to see the formula for the given name and vice versa. Use up and down arrows in upper right corner to view the next ion. **

Free iOS App: Physics 101 Calculator

Written by Nathan Smith on . Posted in iOS Apps, Mobile Apps, STEM and STEAM


Featured in top Education Apps on the App Store

I began writing this app for personal use while taking Physics in college to cut my homework time in half, and I ended up getting an A in the class!  

Physics 101 Calculator was designed to make homework a breeze. Not only does it provide a single source for all your physics formulas, but it also features a quick calculator to save you from all the tedious algebra. Just find the formula for a problem you wish to solve, enter the known values in the correct fields, and Physics 101 Calculator will do the rest!

There are many formulas in Newton Mechanics so making a complete database is an ongoing process. Look for updates and if there are any specific formulas you would like me to add or you notice one of the calculations in incorrect in any way (units or value) PLEASE send me an email so I can take care of it asap. I appreciate and welcome any criticism or praise you may have. And I hope you enjoy Physics 101 Calculator.

Physics 101 Calculator Includes:
– Database of 30+ Newton Mechanics Formulas
– MagicSolver *beta
– 2D Motion
– Circular Motion
– Springs
– Universal Gravitation
– Units Converter
– Formula-Specific Calculators for quick solutions
– Trig Calculator
– Degree to Radian Converter
– SI Units
– Variable Descriptions

MagicSolver makes physics even easier! Almost too easy, I feel guilty providing you with such a powerful tool. Just enter every value you know and it will find every possible solution to the problem and show you the steps to solve it! Don't show your physics professors this 😉

Free iOS App: Atom-Builder

Written by Nathan Smith on . Posted in iOS Apps, Mobile Apps, STEM and STEAM


Slate and Tablets is back with Atom-Builder, an exciting game designed to teach students the skills they need to count protons, neutrons, and electrons in an atom. For the first time ever in the classroom, leverage the powerful Gamecenter to challenge students with our leaderboard and achievements. Use it in your course as homework or a worksheet for atomic structure and particle counting!  

Warning – app may cause addiction to chemistry class.  


– Learn without the clock in practice mode, where you can Tweet atoms you build directly from the app.

– Race the clock to score as many points as you can! Earn extra points for combos, but be careful as the game gets harder when you score higher!

– Tweet your accomplishments and high scores when you achieve atomic greatness!

– Compete for the first time in the classroom through Gamecenter, by earning achievements and sharing them with your friends.

– Teachers: Assign Atom Builder for homework or classwork, and students can email a screenshot of their high score!

Free iOS App: Prism Lab

Written by Nathan Smith on . Posted in iOS Apps, Mobile Apps, STEM and STEAM


A small application that simulates lasers going through prisms (objects capable of refracting, reflecting and decompose light) using Snell's law.

When light travels from one environment to another, it changes velocity modifying its trajectory. The entry angle and the refraction indices of the prism and the environment determine the amount of light reflected and refracted, or if only one them will occur.

Just by moving the light source, you can calculate the entry and exit angles, you can use different materials for the environment or the prism, as well as different shapes.

Useful for those in the fields of physics/optics.
