### 5/5 — Great app

*2025-01-05, version 2.14.12*

Great

### 5/5 — Amazing

*2024-11-05*

Worth the money

**Developer response:** Thanks for the review! Enjoy the app and let me know if I can improve it in any way. Cheers, Darren.

### 5/5 — This app is going to be so cool next time I fly on a plane

*2024-10-30*

I love that you made this app, it’s amazing and so easy to use. I’m an aviation enthusiast and I can’t wait to use this when I get on a plane next.

One other thing I appreciate a lot, thank you for being a human who is going through and replying to these reviews and not a bot that puts the same thing. That’s underrated. Keep up the work!

**Developer response:** Thank you so much for the thoughtful review! Darren.

### 5/5 — VOR OBS reverses sensing

*2024-10-26*

Displays like a back course . Need fix so TO indication results in flight to needle Are you going to fix the reverse sending BC VOR Needles? I don’t want to buy premium til I see the repaired.

**Developer response:** Hi there. This is fixed in the latest release.

### 5/5 — Brilliant product

*2024-09-13*

I have this installed on my iPad and I use it in my AION EVTOL, The depth of this program is incredible

**Developer response:** Thank you so much for the review! Your EVTOL design is incredible and I ams so happy that you have chosen fDeck as its flight instrumentation :-) Let me know if you need anything improved. Regards, Darren.

### 5/5 — Really cool app

*2024-09-02*

I have been searching for this app for a long time. There used to be similar ones but they disappeared. Thanks to the author. Keep up the good work.

**Developer response:** Thanks Mike, appreciated, and I am happy that you found my app. All the best, Darren.

### 5/5 — Truly excellent

*2024-08-19*

Beautiful app, clearly with a great deal of care and attention in its development. Great for simming but I’m also using it in real life as a heading bug tool on an aircraft that doesn’t have one fitted. £30 seems a reasonable price for a lifetime unlock and the dev is very responsive to feature suggestions.

**Developer response:** Thank you for taking the time to review, it is very much appreciated! Please keep the ideas to make the app even better coming! Cheers, Darren.

### 5/5 — Very useful App

*2024-05-01, version 2.13.16*

This app is really good, many useful features for GA pilots.

### 5/5 — A must have if you fly an ultralight!

*2024-04-22*

This is a very valuable tool have on your instrument panel.

**Developer response:** Amazing to hear that you think so Rick, just let me know if you have any improvement ideas. Cheers, Darren.

### 5/5 — Flight deck

*2024-03-13*

This is the perfect companion for the road or air! I use it daily!

**Developer response:** Thank you for the review. Please let me know if there is anything I can do to help.

### 5/5 — Updated review: Weather instruments

*2023-12-19*

I'm updating my review to highlight the reworked weather instrument. The addition of the radar, TAFS & METARS, is a fantastic enhancement, especially with the very intuitive selection buttons.  I use this when paramotoring, which is extremely weather dependent and this is a very welcome update.

Now, seeing as there is one button available, have you thought about adding local NOTAMS 😊 🙏.

**Developer response:** Thank you so much for the review. As always just reach out to me if there is anything I can do to make it better for you.

### 5/5 — I LOVE FDECK

*2023-12-15*

I always was an aviation fan ever since 2021 and this helps me so much with learning aviation

**Developer response:** Great feedback, thank you for the review. Darren.

### 5/5 — Not a gimmick

*2023-12-13*

I was very pleasantly surprised when downloaded this app. Just wanted some decent compass. But this app can really be a nice addition to the flight instrument with lots of extra features for preflight preparation. Very professional design and functionality. Well done developers 👏🏻

**Developer response:** Thank you. Just a developer singular 😄 Glad you like it. Tell your friends! All the best, Darren.

### 5/5 — Great for Land Vehicles Too!

*2023-11-27*

I bought this app for the inclinometer and found it super useful for vehicles. The extra aviation instrumentation is a bonus. Thanks for putting this out. Awesome

**Developer response:** And thank YOU for using my app. Feel free to send over any improvement suggestions should you have any. Regards, Darren.

### 5/5 — Ottimo

*2023-11-12*

Molto utile

**Developer response:** grazie per la recensione!

## Most critical reviews (10 lowest-rated)

### 1/5 — No updates

*2025-03-01, version 2.14.12*

There are improvements that can be made to this app.

### 1/5 — The free version is almost useless due to ads

*2024-11-03*

The free version is not free. It’s made almost useless by full screen ads. Some of them you can’t even close. You have to close and reopen the app. I wanted just the altimeter as I drive through the mountains a lot. But after about 2 minutes you are forced to fumble with the phone and close an advert. Extremely bad when driving through mountains. Maybe make the free version actually free.

**Developer response:** The free version is indeed totally free. I put a huge amount of work into making and maintaining this app for people. If you find the ads inconvenient then you can subscribe for the price of a cup of coffee per month. The ads can be closed without exiting the app. Thanks for the feedback though, Darren.

### 1/5 — Doesn’t work on iPhone SE

*2021-04-01*

Wrong screen format so can’t use the app.

**Developer response:** Hi there. Please try the latest release.

### 2/5 — Does not support iPad split screen

*2023-02-03*

The app seems well done, but I want to use it in conjunction with a different app on my iPad, and split screen is not allowed so it does me no good. Deleted.

**Developer response:** Each to their own! Thanks for the review anyhow....I think!

### 2/5 — Looks great, doesnt work

*2022-01-25, version 2.7.1*

Great idea and the app looks amazing. I was really looking forward to using it with the X Plane simulator. Unfortunately it’s very glitchy and the connection to the simulator mostly doesn’t work.Too bad maybe a later version will do better.

### 3/5 — Nett aber Fehlerhaft

*2025-04-15*

Ich habe die App heute mal im Flugzeug getestet. Bei einer Kurve mit 17 grad Querneigung nach Rechts zeigt es mir einen Pitch von 10 an. Also ein Steigen, obwohl wir Sanken. Die Querneigung zeigte auch im Horizontalflug noch einen Wert vom 3 Grad für mehrere Minuten an. Der Kreiselkompass zeigt auch Fehler wie man sie vom einem Schnapskompass erwartet, aber nicht von einem Kurskreisel.

Als Spielerei nett, aber im Cockpit hat das wirklich nichts zu suchen.

**Developer response:** The AI is very sensitive to device and OS version, environment and installation. It it not meant to be a primary instrument. Most users use fDeck for the other 10 instruments, virtual nav, real-time weather, TAF and METARs, Traffic avoidance, route planning ans situational awareness. I have users successfuly running multiple instances of fDeck in their cockpits, so saying it has no place in the cockpit is your opinion, which I respect, thanks for the feedback, Regards, Darren.

### 3/5 — Works great (mostly)

*2025-03-13, version 2.14.16*

Works great for almost everything except the compass is inverted, and so is the pointer in the map

### 4/5 — No sectionals

*2024-07-30*

Flight deck portion of the APP works but I can’t get any of the maps to load/display.

**Developer response:** Try zooming out, or switching the map base layer from vfr-hybrid to sectionals and see if that helps, Regards Darren.

### 4/5 — Hoping it works on my ultralight.

*2023-02-26, version 2.8.42*

I’m going to use this on my Affordaplane Ultralight.
I’ll give a honest review when I start using it.
I’ll show actual video on my YouTube channel of me using this. 
I hope it works as good as it works.

### 4/5 — Good on a properly mounted IPhone

*2022-10-05*

Used it in car initially and seemed OK. Then mounted iPhone in C42 microlight and was impressed by most. Altimeter both on GPS and barometer compared accurately to on board altimeter. The standard and VOR compass was very good and the ability to set user VOR is good. VSI not so good as it showed me climbing at 1500ft pm when actual 700ft pm. Artificial Horizon worked reasonably well but as VFR aircraft that wouldn’t be put to the test. Local weather and wind is nice feature as guide but pressure was alway 1mb less. Was used on iPhone 12. A nice addition would be to have CAA overlay in UK. I paid £10 to remove ads on iPad but ads never appeared on iPhone. Worth £10 for developers effort

**Developer response:** Hello and thank you so much for the review. Its great to hear from users in the field and I would really appreciate it if you wanted to send any more detailed feedback to apps@sensorworks.co.uk for me to make the app better. Your subscription covers you across all devices - as many as you want - you don't need separate subscriptions for phone and tablet - so you didn't see ads on your phone as you had already subscribed via your tablet. Great to hear from you - please reach out if I can help or answer any more questions in any way! Darren.

### 5/5 — Wirklich nützlich!

*2026-08-17*

Ich trainiere gerade mit meinem Utraleichtflugzeug das Navigieren nach VOR/ADF, um mich auf die PPL Prüfung vorzubereiten. Das geht ganz hervorragend mit dieser wirklich schön gemachten App. Sogar Wetter, Verkehr und Flugkarten und vieles mehr sind enthalten. Echt klasse! Wenn jetzt noch eine App für die Apple-Watch dazu kommt, ist es perfekt.

### 5/5 — Minor tweaking

*2026-06-18*

Fantastic app…I use it for some secondary flight instruments for flying my ultralight. I wonder if the VSI could be made easier to configure for scale, I never see 1000 ft/m so 2000 is redundant . Could we see 0-1000 so the scale would be easier to read and more accurate for small altitude changes?  Thanks again…… love the app!

### 5/5 — Very useful App

*2026-04-20*

I have just come back to this app. I had forgotten how brilliant it was. It works well for GA pilots and on X-plane simulator as well. I highly recommend.

**Developer response:** Thank you so much for the review. It was specifically built for GA pilots so I'm glad it is hitting the mark. Please let me know if you have any ideas for improvement/addition. Regards, Darren.

### 5/5 — Best aviation app hands down!

*2026-02-14*

I’ve used many aviation apps but this one is hands down the most useful. Super easy to navigate its features and lots of options. It’s the perfect back up!!

### 5/5 — Great app!

*2026-02-02*

Extremely easy to use. Very well laid out. You can spent a lot more on something else and get a lot less. Highly recommended!! Only problem I had was trying to upgrade my service if you can believe it.

### 5/5 — A Happy Customer

*2026-01-08*

The App is an excellent tool to learn, teach, or practice the use of many avionics devices that you might not have in your plane; and the developer is great at responding to questions, comments, or suggestions.

**Developer response:** Thanks for the review and feedback - I built the app to do exactly this so I am pleased it is helping you! Regards, Darren.

### 5/5 — Incredibly useful

*2025-12-16*

Really just a great app, it does exactly what it says and does it well.

**Developer response:** Thank you so much for the review! Regards, Darren.

### 5/5 — Excellent App!

*2025-05-04*

Use it every flight! I use both the GPS Ground Speed and the ADF instrument (GPS based) on every flight. Several other well appointed instruments as well. Very easy to see in flight and works flawlessly. The ADF points to the GPS target entered and gives DME. A quick glance is all that is needed to see if you are heading to your target. My private grass strip is somewhat hidden in a forest so this is quite helpful. Thanks!!

**Developer response:** And this is why I built the app and continue to develop it! For users like this. So pleased that fDeck is proving useful to you and I am super happy to hear how you are using it. If you feel so inclined to grab some photos of you using it in your cockpit and email them one to me I would be very pleased! Thanks again - Darren.

### 5/5 — Impressive NAV app

*2025-04-21*

Concise, easy to configure, even easier to use. H/T to the developer. Thanks for the work and effort you have put into this fine app. 

Would like to see compass work in horizontal configuration (180 degrees off (iPhone SE)); and, just for driving fun, a CarPlay functionality to impress my in car navigation officer.

**Developer response:** Thanks so much for taking the time to review, I really appreciate it. Noted re. the compass, I'll look into it. Car play is on the backlog and agree it would be quite cool to have the instruments working in the car :-)

### 5/5 — Excellent addition to the cockpit

*2025-03-19*

I have been using this as an additional aid to navigating since January-it works fantastically as a stand alone product, very flexible in what you can see. I am currently set up using it as 1x2 instruments in a 1/3 screen to SkyDemon. At a glance gives me great flight and situational awareness. Looking forward to the potential EFIS version. Good work.

**Developer response:** Great to hear how you are using my app and I am glad you are finding it useful. Please let me know if I can do anything to make it better! Cheers, Darren.
