Tools for the trades

Numbers you can cut to.

We build small, focused calculator apps for people who work with their hands. Pay once, no account, and they work where there's no signal: in a vault, a basement or a plant.

01

Conduit bending

90° stubs, back-to-back 90s, offsets, kicks, 3- and 4-point saddles and segment bends for EMT, IMC and rigid, with your bender's own deducts. Marks first, then how to bend it.

02

Pipe offsets, simple and rolling

Set, run and travel at any fitting angle. On a rolling offset the rise and roll are combined first, so the multiplier is applied once, not twice.

03

Cut length, end by end

Each end is worked out on its own, because an elbow at one end and a tee at the other is normal. It won't give you a cut until both ends are filled in.

04

Eight ways to join pipe

Butt weld, socket weld, threaded, copper, PVC, press fit and grooved, each with the right take-out for that joint.

05

Wire and power

New in 1.2: voltage drop, wire size and max run for copper or aluminum, amps from watts, kW, kVA or horsepower, Ohm's law and transformer current. Every answer shows the math.

06

Sources named

Bender numbers come from the Greenlee and Klein bender guides; pipe and fitting dimensions from published standards and catalogues. The app says which. Where published sources disagree, it tells you.

About

Small tools, done properly.

Batishev Enterprises LLC is a small, independent company. We make apps that do one job for one trade and do it well, and we charge a fair one-time price instead of a yearly subscription.

Our apps are not affiliated with or endorsed by any standards body, manufacturer or publisher. Standards are named only so you know where a number came from.
