### 1/5 — Doesn’t work

*2025-12-22, version 1.0*

Tried to open a .ace file that works fine in Garmin’s checklist editor, but this tool says it’s not valid I tried to report it to the developer, but the button that is supposed to submit the report is INOP.

### 5/5 — Works great!

*2025-07-15, version 1.0*

Was so happy to find this and that it worked just as described. Had no issues making the updates I wanted. The edited checklist loaded up in my G3X no problems. 
Thanks so much!

### 5/5 — Great App!

*2025-07-11, version 1.0*

I used the old PC and legacy garmin software to make my G3X checklists back in 2021.  I made some additions along the way, but getting out the old PC to do it was always a hurdle.  I needed to make some additions to my gear emergency checklist but was dragging my feet because I knew it would be a pain to get the old software going again.  I tried editing my file with ACE-Editor on my iPad Pro and it worked great.  Very intuitive and fast.  Thanks for the great piece of software.

### 5/5 — Very very helpful !!

*2025-05-06, version 1.0*

You can finally reorder your items!

### 5/5 — Just what we needed

*2024-05-05, version 1.0*

This is great. At last. So much better than the clunky windows app. Seems to work perfectly.
