What customers say about us

Great app and so far with 9 helicopters and 22 personnel with access to the information, we can now truly track the performance of each aircraft and each pilot can see what the aircraft is doing performance wise and all with a couple of simple and easy clicks on the app.

I emailed Helitrends Custumer Support and within 48 hours response was “sure we can add this helicopter”. I supplied Helitrends with the required aircraft documentation and performance charts and by January 2023, the 505 was added to the app and it works well. It has been disseminated to the 505 community and is now being widely utilized.
