User reviews

Excellent app!

Well done! Weight and balance is amazing
Performance is perfect and so easy
I would of like a checklist

Response from tech support is nil

I ask why the performance numbers on max power disagrees with the apps numbers. Submitted this question many time without an answer. Great graphics. Now if I could rely on the data it puts out.....

Get rid of slide bar

The slide bar just doesn't work for my normal size fingers. Impossible to set the exact weights. If you fly in high DA and need to know your W&B to the pound, stick to pen and paper.

Great app and worth the money - almost read to understand.

Superb app, makes ease of all calculations required and I can see it being especially good for doing very quick weight and balance calcs when doing multiple lifts / tours.

I have rated this a four for three reasons...

1. It would be nice if the app would automatically tell you maximum fuel allowed on board for your given weight configuration - you have to remember to increase the slider currently. Not a problem with the app at all but it would be a nice feature.

2. For owners of multiple types of Robinson machines R22 / R44 and their various models it would be nice if there was a bundle package that included all types for a reduced overall price. Currently it is the same price for each one - so multiple discounts would be good or say 60 all in?? I would have certainly taken all of them if there was a bundle discount.

3. It would also be nice if the app worked on the iPhone too without having to buy the iPhone specific versions.

Other than those niggles it is a great and useful app.

Stopped working, No support!

It worked for a while on my iPad 2, started having problems when I updated to ios8. Screen locks with bizarre COG value, renders Ap unusable. I deleted and started over with identical results. No response from several emails or facebook post.
