EveryCircuit v1.14 APK

All joking aside, this time you will understand how electronic circuits work.
Build any circuit, tap play button, and watch dynamic voltage, current, and charge animations. This gives you insight into circuit operation like no equation does.
While simulation is running, adjust circuit parameters with analog knob, and the circuit responds to your actions in real time. You can even generate an arbitrary input signal with your finger!
That's interactivity and innovation you can't find in best SPICE tools for PC like Multisim, LTspice, OrCad or PSpice (trademarks belong to their respective owners).
EveryCircuit is not just an eye candy. Under the hood it packs custom-built simulation engine optimized for interactive mobile use, serious numerical methods, and realistic device models. In short, Ohm's law, Kirchhoff's current and voltage laws, nonlinear semiconductor device equations, and all the good stuff is there.
Growing library of components gives you freedom to design any analog or digital circuit from a simple voltage divider to transistor-level masterpiece.
Schematic editor features automatic wire routing, and minimalistic user interface. No nonsense, less tapping, more productivity.
Simplicity, innovation, and power, combined with mobility, make EveryCircuit a must-have companion for high school science and physics students, electrical engineering college students, breadboard and printed circuit board (PCB) enthusiasts, and ham radio hobbyists.
Free version has limited sandbox area, but it can still impress you. If you need a larger playground, a full version is available. The full version will employ all of your imagination, and all the screen area of your tablet.

In Swampy's Story, play seven themed chapters over 140 levels. Collect Swampy's ducks and shower items to unlock new puzzles and bonus levels. FREE levels are added to Swampy's Story regularly!

Cranky's Story
Cranky is the toughest alligator around and so are his puzzles! Play the first two chapters across 40 levels and test your puzzle solving skills with Crank's Challenge. Cranky's Challenge is a game within a game. Four unique puzzle packs with 16 total levels for the most-skilled puzzle solvers.

Humorous story moments and richly-detailed graphics bring this subterranean world to life! Check for updates often.
AMAZING LIFELIKE FLUID PHYSICS Go with the flow! Swipe, slosh, and splash to guide fresh water, dirty water, and ooze through increasingly challenging scenarios.

COLLECTIBLES, CHALLENGES, AND BONUS LEVELS Collect Swampy's shower items and complete Cranky's Challenge to unlock bonus levels. "Tri-Duck" each chapter and tap around for secret levels and even more surprises! Visit www.facebook.com/WheresMyWater for more hints, tips and secrets.
