### 4/5 — Looking for (Anti-Ice System) diagrams.

*2026-07-16, version 7.1.3*

Waiting for (Anti-Ice System), but the app is very good for study.

### 5/5 — Excellent App

*2025-01-13, version 7.1.2*

I am a 737 rated pilot, during revision periods for the simulator or to generally improve familiarity with systems I often use these diagrams. They offer a great mix of system diagrams in conjunction with the aircraft panel. This allows a failure to be presented and the required switches operated as per the drill while observing related panel system lights.

### 5/5 — Fantastic

*2025-01-02, version 7.1.2*

Incredible app. Easy to use and easy to learn.

### 5/5 — Indispensible

*2024-11-26, version 7.1.2*

If you really need to understand how the B737 systems work this is the app. Simulate all of you normal and non normal and see what actually happens.
The cockpit poster is also very helpful, with short essential explanations for each dial and buttons.

### 5/5 — B737MAX

*2024-11-08*

update B737MAX please，really need it

### 5/5 — Beautiful

*2024-03-01, version 6.9*

Your app is great. Best diagrams out there. Way clearer than the FCOM. I hope you continue to improve it with new content. Engine start sequence, oil system etc… for example :)

### 4/5 — Excellent for initial type rating on B737NG

*2024-02-12, version 6.9*

I was bit skeptical before buying this app as it is quite expensive. It took me just 30 min to play and I am already loving it. I am a piston pilot with just 250hours going for first type rating on a jet. It is certainly helpful tool to understand the relationship with systems buttons on overhead panel and system schematics on B737NG

However, some buttons are still bit itchy and hope the developer  will fix this in future. 

Great app. Too expensive though !

### 5/5 — Great resource

*2023-12-04, version 6.9*

App works well and effectively demonstrates systems. Worth while for learning or as a troubleshooting aid.

### 5/5 — Beautiful Boeing 737-800

*2023-04-09, version 6.9*

This is the most comprehensive most simple and easy way to not only to understand the system but also to learn how to operate the system and touch the controls before even going to the sim or the aircraft itself 
Wow this is a must for any one attempt to get typed on the gorgeous and beautiful Boeing 737-800 
Thank you is not even enough 
You are well appreciated thank you for the good and beautiful work.

### 5/5 — All systems simulation are very useful for understanding

*2023-04-03, version 6.9*
