Tile Calc LE app for iPhone and iPad

Tile Calc LE is the light edition of Tile Calc.
It calculates the number of tiles you need for a rectangle area taking in account the distance between the tiles.
Tile Calc LE (Light Edition) does not provide advanced math algorithms for calculating the number of tiles.
It also does only support quadratic tiles.
Usage is quite simple:
Enter the tilesize and the distance between the tiles.
Then press the tile to store the values.
Press the back button and enter the lenght and broad of the area.
Press somewhere on the tiled area to calculate the number of tiles needed.
For easier use the fields are splitted in ft, in and 1/10th inch.
With the big number keyboard wrong input is made impossible.
Values for tilesize and distance is stored. No need to input the size if it is the same on the next start of the app.
