User Reviews

The app is notably easy to use with a clean, single-page interface that shows all calculations, updates results in real time, and displays both local and Zulu times—making preflight planning fast and efficient. The main drawback mentioned across multiple reviews is the pricing model, which users feel is deceptive since the app isn’t actually free.

Pros

Very user-friendly / easy to use
All calculations on a single page
Real-time / instant results as data is entered
Local and Zulu times shown at the top
Strong preflight planning/nav log capabilities and speed

Cons

Pricing concerns: marketed as free but requires payment (subscription or one-time purchase), seen as deceptive

Recent reviews

Used it a bunch of times for some recent flights. Very user friendly

Great for quick calculations on ground and in flight

by N1*****, 2025-10-12

Very simple, the app isn't actually free. It costs $2.99/mo or a lifetime purchase of $8.99. Very deceptive, but if you don't mind the mild case of false advertising, it appears to work good.
