## Most critical reviews (9 lowest-rated)

### 1/5 — Waste of money do not buy.

*2025-01-05*

Freezes up does not work correctly on iPad mini. Complete waste of money.

### 1/5 — Not working

*2024-09-17*

Direct button is not working and also most of the time gps error and irs error is coming and getting stuck

### 1/5 — Useless

*2024-06-12*

This thing is useless.  Embarrassing at how limited and bad it is.   There is no guide to how to set the app up or change settings.   The screenshots in the App Store I don’t see how to get to in the app.  The actual sim part of the app is so thin.  Can’t even load in weight or cg without getting errors.   This thing isn’t even worth 99 cents let alone what they are charging.  Do not buy this garbage.

### 1/5 — It doesn’t work properly.

*2024-05-13*

It doesn’t work because I can’t simulate the flight.

### 1/5 — Crashes

*2023-10-19*

I have multiple screen grabs of unknown errors followed by a totally blank FMS. The ZFWCG/ZFW inputs don’t work either - way over price for $60 - no way either if contacting the company directly to try and resolve the matter. Annoying

### 1/5 — Basic functions for too much price

*2022-11-15*

This app is very basic and the price is too much for typing practice on mcdu setup for departure, rest of functions not working, no tutorial included for the app. Very disappointed with this app is a waste of money.

### 2/5 — Need update

*2022-11-03*

App crashed once clearing waypoint from airways page
and we can’t takeoff and put QNH and a lot of lagging during using it

### 2/5 — This is a $10 App, and that’s generous.

*2022-10-18*

Limited functionality. KG only, KG/LBS in settings is “NOT ALLOWED”. 

No flight progress simulation, the advance function simply moves airplane icon to the next fix in the FP.

With a FP entered, the course on the ND regarding pseudo-waypoints is all kinds of wrong.

I had seen enough, deleted and seeking refund.

**Developer response:** Dear Sir or Madam. Thank you for your feedback. The function to switch from kg to lbs will be available in the next version. Generally, the app is made for airline pilots in typerating training and therefore aims to realistically represent all functions of the FMS down to the smallest detail. 
By scrolling through the waypoints the user can observe a realistic FMS behaviour in all flight phases. In professional pilot training a flight progress simulation has no special value, as there is usually no time to complete flights in real time. For this kind of functions better refer to non-professional tools like "Flight Simulator".

### 5/5 — A+

*2022-10-03*

Solid Airbus A320 FMS trainer! I downloaded the app when it first came out and I haven’t been able to put down my iPad down since. Really great product for those that are new to the Airbus fleet or those wanting to keep their skills sharp, this is the app for you. 
 
Disclaimer: This is not a substitute for your airline specific FMS, and probably doesn’t have all the bells and whistles you’re accustomed to, but is still a fantastic trainer for the basics.
