### 1/5 — Terrible system

*2025-06-26*

Is takes forever to synch, it's hard to use, has a lot of bugs, doesn't have an option to truly work offline and than synch what you did when you have internet. I miss jet insight so bad!

### 1/5 — Unusable app, constantly crashing.

*2025-06-20*

This app crashes frequently and is highly unstable. I’ve tried reinstalling it, updating my device, and other basic troubleshooting steps, but the issue persists. As a pilot who depends on this for scheduling, it’s incredibly frustrating.

### 1/5 — Constant Crashing – Unusable

*2025-06-20*

This app crashes every single time I try to open it. I’ve tried reinstalling, restarting my phone, and updating everything, but nothing works. Completely unusable in its current state. Please fix this ASAP — it’s essential for work and this is unacceptable.

### 1/5 — Just dead

*2025-06-18*

Worked somewhat okay for months and then suddenly died. Impossible to log in. Impossible to change the server address. Can’t even run open the demo. The app is just dead as a dodo.

### 1/5 — Crashes steady

*2025-06-07, version 4.7.1*

App since iOS 18.5 crashes consistently

### 1/5 — Slow and I mean slow

*2025-03-28, version 4.7.1*

Syncing can take 5-10 minutes and stops if you go to another app. That’s if it doesn’t crash. Terrible. I would be embarrassed to have written this app.

### 1/5 — Terrible app

*2025-02-20*

Horrible app. never works.

### 1/5 — Improve the app

*2025-02-04*

One of the worst apps on planet earth!

### 1/5 — Issues Syncing

*2025-01-25, version 4.7.1*

The app constantly crashes while syncing. It also takes a very long time to sync. There should be an option to automatically download docs for my trips and to automatically update airport data. The developer is well aware that there are issues with this app, but they do absolutely nothing to fix them.

### 1/5 — Slow

*2024-12-01*

Sync takes forever and drains battery, something as simple as a schedule shouldn’t take this long to load. I also get Sync errors almost every time I open the app.
