Why pilots keep it on the home screen

The frustrating parts of a flight are rarely the flying. These apps take care of the admin and give you the numbers you need.

W&B you can trust

Every station arm and envelope comes from the flight manual. Both CG envelopes update live as you move a slider, and zero fuel is checked as well as takeoff.

Made for the cockpit

Big controls, dark screens and answers in two taps. Recalculate when the client turns up with an extra bag, without switching apps.

Performance from the charts

HIGE, HOGE, rate of climb and power assurance worked on the exact chart your aircraft and its supplements call for.

Any unit, all at once

Fuel in litres, US gallons, lb, kg and percent side by side. Weights in lb and kg. No more googling 109 kg in pounds.

Weather without the faff

METARs and TAFs in two taps, route weather briefings as a PDF, and live winds feeding your in-flight numbers.

Paperwork in seconds

Sign once and every W&B, nav log and briefing is a shareable PDF. Email it or print it before the passengers are strapped in.

Free tools, no app needed

What pilots say

Reviews from the App Store and Google Play.

“By far one of the best apps I have used for helicopter planning, performance and limitations. I love that you can check the VNE limits for doors removed or open without having to check the manual on the H125. The flight section is brilliant, you have all your information at a glance.”
Justin · Tool in the Cockpit · App Store
“Helping us tremendously, far superior to anything else on the market right now.”
Bravo407 · Tool in the Cockpit · App Store
“Having used many in-flight and planning helicopter apps, this one tops the list. From planning to in-flight data, I am amazed at how much information is available.”
Kevin · Tool in the Cockpit · App Store
“Great app for being free. It's worth a download, especially if you are new to flying. Using this for H125 commercial ops.”
Jonathon Lanza · Tool in the Cockpit · Google Play
“Great app. Does everything you need, including the option to email the W&B.”
Frederick Green · Tool in the Cockpit · Google Play
“Great app for people that fly the AS350 and the RH series.”
Nick Berriman · Tool in the Cockpit · Google Play
“Great app for Cabri pilots. I use it mainly for W&B and power ceilings, but the nav planning feature is a nice addition. It's the best Cabri app I have found.”
Google Play user · I Fly Cabri G2 · Google Play
“Nice app, doing all the things I need for my flights and it's user friendly.”

Built in the cockpit, not a boardroom

Chopchop Apps is run by a working commercial helicopter pilot. Every feature started as a real frustration: a passenger arriving with extra luggage, a client asking for a last minute change of plan, or three different websites and a printer standing between you and a flight.

We build tools that turn those annoying processes into something quick, easy and even enjoyable. If it improves the pilot's day, we want to build it.
