SmashImpacts is an app which can let you make powerful attack to destory various objects inside it, make the fierce visual and sounds effect which can shock others around you. Also, make priest spells and magic attack to objects inside it.

You can destroy objects (like brick wall, armor plate, glass window, wood plank, etc), just stretch and shake or punch fist with iPhone or iPod touch. Acting like mana and spells attack in game. Punch your fist in different direction, which would cause relative smash impact and effect on the positions of objects.

Choose different kinds of hits, punchs or attack styles (Like Sorceress Lightning Wave, Blaze Fist, Sorceress Frost, Figther Scream Punch, Marvel Energy Shoot, etc), with select a set of target objects to punch, which would cause various visual and sound effects of smash depending on your hit speed, direction.

Punch with holding iPhone and iPod Touch as well as you can, this app can record your punch max speed, hit frequency, hits amount number. You can send your awesome records to your friends email.

This is far more than a entertainment app. You can also use it do personal physical exercises and punch exercises, test your punch speed.

Acceleration 3D Detector is an iphone application which can
display 3D acceleration vector and record acceleration vector
values (magnitude, direction, and coordinate values in x,y,z axis);

one of significant feature of this app: you can set up a set of
time points in the acceleration testing, each time point can
record the instant acceleration vector values. The time points
setting range from 0 minutes 0 seconds 100 millisecond to
59 minutes 59 seconds 900 millisecond. The Minimum time point interval is
100 millisecond.(if your device has lower
memory, recommend not set more than 18 time points)

Features:
-set number of time points to record vector values,angle, velocity increment;
-render vector in a 3D space screen.
-display acceleration vector values;
-display velocity increment values(in some condition could be instantaneous
velocity value - like movement from 0 velocity);
-record acceleration and velocity increment vector at values each time point.
-store vector values of time points into history saving list.
-movement route track display.

The Acceleration 3D Tracker is an iPhone application for Acceleration 3D vector tracking, rendering and testing.
You can use this app to check your movement acceleration value in length/magnitude, and direction, angle to each 3D axis(x,y,z).It has a feature which can display a route when you make a acceleration movment with the device. Record the vector which has maximum value in length / magnitude.

Features:
- display instant acceleration 3D value, vector, and vector angle, direction.
-render real-time acceleration vector in a 3D space screen.
- record a set of acceleration vector values which have maximum absolute
values in each axis(like vector which has max value in x, max value in y, etc).
- record instantaneous velocity (speed) increment.
- store acceleration vector values and information in history saving list.
- movement route track display.
