Review summary

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

2025-10-08	Af*****	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.

2025-08-06	Pa*****	This is a bad app. Markets itself as free just to ask for immediate purchase upon opening

2025-07-05	Hu*****	Easy to use, I like the layout and having the local and zulu times at the top are a nice touch. Would like to have a pressure/density altitude calculator as well tho! Don’t know why thats not on here as it seems like a simple piece missing. Just plugging in elevation, altimeter setting and temperature.

2025-03-21	mc*****	This E6B app is perfect for filling out your nav log or for quick reference while in flight. It is designed to simply enter your known data and supplies your unknowns in a logical format. All the calculations are on a single page, so there is no page flopping when looking for a previous solution. The built-in keyboard facilitates the ease of use and reduces the chance of error especially when trying to get a quick calculation done. Highly recommend this E6B app.

2025-02-15	Pi*****	The E6B from FLT1 is missing an important feature in weight and balance. There needs to be a function to subtract weight for fuel burn. The weight and balance calculator only allows for weight to be added. Once that is added it will get 5 Stars.

2024-09-10	Pe*****	Simple and clear. Made pre-flight planning and performance calculations a breeze. Interpolation tool is a nice touch - haven’t seen it anywhere else. Simple and robust, with adequate details, which is what you want while flying.

2024-09-06	nm*****	Simple and easy to use. Made planning xc flights fast, esp. when variables change, like baro, temp, wind dir./ speed, etc. Zulu time (and local) on top of screen is a nice bonus. Weight and balance calculator too.
