:: Store Projects ::
Blaster's App contains a project system that allows for the storage of all calculations and layouts associated to any job. Set GPS coordinates for your projects and the app will automatically look them up when you arrive on site and use that location's project by default.

:: Borehole Layout ::
The Borehole Layout system makes the tedious task of laying out a job's boreholes as easy as dragging your finger to connect the holes and assign your custom delays. It allows blasters to lay out their hole design and timing in seconds rather than hours. Share your layout with your team or print it by exporting it from the app. Exported layouts can then be imported on another device running Blasters App. Its that easy.

Easily and quickly assign delays and sequences using just your finger. Holes within 7ms are instantly shown in red. Zoom in to work on details and zoom out to see the layout as a whole.
Turn on Heat Map for a visual representation of the shots timing sequence. With a simple tap, toggle your view between sequence timing and per hole delay.

:: Custom Calculators ::
Each calculator uses the app's custom keypad to make data entry quick and easy. SAVE your calculation to a current project or review past results from the LOAD screen. Tap the ? for more information about each calculators equations and functionality.

"Blaster's app" is the all-in-one tool for blasters!

General blaster

Very functional.. bore hole layout is a little tough to operate needs a video tutorial to show how to work all options's a great app needs GPS waypoints so you can get distances from shot to closest house or roads also the price of this app is a little steep but if the above things were added I would call it a good buy

A must have for Blaster

This App is a "must" have for licensed blasters.
I'm a blasting/explosives inspector for the State of Pa.
I use this App to review blast records and for complaint investigations.
When I was blasting this App would have saved me so much time.
Puts all the formulas you need to blast right at your finger tips.
Clearly a huge giant step into the future!
Well worth every dollar!
