Hey everyone — I've been working on E6B Flight Computer, a Connect IQ app that puts E6B-style flight planning calculations on a Garmin watch, and I'd really like feedback from people who actually fly before I keep iterating on it.
The idea: enter whatever values you know and it auto-solves the rest (wind correction, ground speed, fuel, climb/descent, holding pattern entry, etc.) — basically the calculations you'd normally run on a physical E6B or a phone app, but on your wrist.
A few things I'm genuinely unsure about and would love opinions on:
- Is this actually useful in practice, or is a watch the wrong form factor for E6B work?
- Which calculations matter most to you — did I miss anything important, or include things nobody actually uses?
- Any UX pain points if you try it? Long-press on a field gets you a plain-language explanation, but I don't know if that's discoverable enough.
- Anything that feels off for how a CFI would want to use this with a student, versus solo cross-country planning?
It runs on Garmin watches across round, square, and rectangular screens (Fenix, Epix, D2, Venu, Forerunner, Venu Sq, and more), Airspeed is free to try with no purchase, and the rest unlocks with a one-time payment if it turns out to be useful to you. Not trying to make this a sales pitch — genuinely want to know if I've built something that holds up against how you actually fly, and what's worth fixing.

Appreciate any thoughts, even blunt ones.
