Construction Blaster Joe Calc

Stop adjusting to your tools. Make your tools adjust to you.
​Construction Blaster Joe isn't a generic calculator built by a guy in an office. It was built by a layout guy with over a decade of experience on the deck, designed to solve the actual headaches that happen on a job site. It is heavy-duty, lightning-fast, and built for the real world.
​🔥 THE FEATURES:
​Interactive 3D Concrete Stair Calculator: Stop guessing soffit lengths and wall-to-crank dimensions. Punch in your rise and run to instantly generate a fully interactive 3D model. Spin it, zoom in, and get every critical measurement mapped out before you cut a single piece of lumber.
​100% Offline (Deep Basement Guarantee): Works perfectly in concrete parkades, underground vaults, and remote subdivisions. If your cell service dies, Blaster Joe keeps running.
​The Custom Toolbelt: Drag, drop, and resize your buttons. Concrete guys can put volume up front; roof framers can lock in Pitch and Hip/Valley. Left-handed? Move the numbers to the other side. Build the exact toolbelt you need.
​Instant Metric/Imperial Translation: End the dimension civil war. Type your millimeter plan numbers, hit the unit button, and instantly see it in feet, inches, and 16ths. No more fractional math in your head.
​The "CYA" History Tape: Save your dimensions, add custom notes (like "Elevator Shaft Wall B"), and keep a running record of your math so you never have to walk back and re-measure.
​Lightning-Fast Touch Interface: Engineered to register the exact microsecond your finger hits the glass so it keeps up with your fastest layout guy. It never drops a number.
​🛑 THE NO-BS GUARANTEE:
Tradesmen hate software subscriptions. Blaster Joe is a one-time, $5 investment. Just like buying a physical tape measure at the hardware store.
​NO Ads.
​NO Monthly Subscriptions.
​NO In-App Purchases.
​NO Internet Required.
