### 3/5 — ForeFlight import failed

*2026-04-10*

App was recommended by friends to help migrate my ForeFlight checklists. After multiple attempts is clear this is not possible, always giving me an error. Perhaps ForeFlight modified their file structure recently?

### 4/5 — Too expensive

*2025-12-22*

Since editing can be done for free with Garmin's software (PC only though) the main value of this app is the conversion  between platform, and that appears to work well (although it'd be great if for export to Foreflight there were a way to control the checklists end up in their Normal / Abnormal / Emergency categories).
Also, in use mode it'd be great if there were a bottom section big enough for the thumb that represents and works like pressing the ENT button to check items off one by one easily.
I appreciate the effort that went into creating this app, but I find it way too expensive when I look at the value it presents to me. For ten bucks I would buy it no questions asked (or I'd pay a one buck per month subscription) - but not ten times as much.

### 5/5 — Finally!

*2025-12-10*

Was able to update a G3X in my Beechcraft without needing to lug my windows 7 laptop into the plane.

### 3/5 — Fine Function. But export to G3X costs $$$

*2025-08-07*

Easy to use. Simply drag to rearrange items. Formatting flexibility enables checklists that are easy to read and potentially use. I say potentially use, because exporting to the g3x native format requires expensive purchase. Might be a 5 Star app, but, it’s too costly.
