Excellent customer support

The configuration of our AW139 corporate helicopter was not available from the list. One e-mail to the developer was all that was needed to have our configuration data added to the App on the following revision. No fuzz efficiency, just the way we like it. Highly recommended!

Great app! Awesome support.

Great app. Awesome support.
I have been using iBal Rotary for a few years now and it a great app and a real time saver. It’s so easy to use and quick and easy to update W&B as loads change. The support from the team is top notch. I would highly recommend this app to anyone flying helos.

Zero fuel? We don't fly to zero fuel.

Would be nice to have an adjustable minimum fuel but the app developer won't add it.
