### 1/5 — What

*2024-03-06*

Most confusing app ever. What does it even do?

### 3/5 — Great App … just missing one important feature.

*2023-11-03*

I love how simplistic and easy to read this app makes your max wind limits. If it had an option to enter current runway, winds and than displayed the current crosswind and headwind it would be perfect. As it stands it is simply a max crosswind and headwind table. Nice app though.

### 2/5 — Needs work

*2023-10-14*

Nice interface but can handle tailwinds  Program takes all wind, winds from the front and back, and breaks them into crosswind and headwind (even if it’s a tailwind).  Should be an easy fix if author gets around to it.
