2. Or connect the iPhone to a iLEVIL „SW“, „AW“ or „Sport“ device (available at the LEVIL company or in many pilot shops) by WIFI device to get precise attitude and GPS data. 
3. A 80 or 360 degree course rose (change with tap on airplane symbol)
4. Magnetic and True GPS track (display in white with with track line)
5. Magnetic or True Heading, heading data is provided by internal compass and is not always reliable.

6. iEFIS Pro version (simple upgrade via inapp purchase!) displays a worldwide airport database and always shows the bearing to the nearest airport from your position with distance, elevation and runway orientation of the main runway of that airport.

### 5/5 — Super nützlich

*2025-08-13*

Klasse App. Spätestens seit einem die Flugleiter nicht mal mehr das Q NH sagen dürfen, würde ich sie nicht mehr missen. Zu bekomme ich immer das nächstgelegene QNH angezeigt.

Wetterradar unterwegs super nützlich mit kurzen Intervallen. Besonders in Verbindung mit Starlink Internet (aber natürlich auch mit mobilen Daten) unverzichtbar. Ein GameChanger.

### 5/5 — Tests in flight

*2019-06-23*

IEFIS PRO was PERFECT during a 3 hour flight in my Lance. Airspeed was perfectly aligned with my Garmin 430. Attitude info matched my panel mount horizon, bank by bank. Climbing attitude matched perfectly as well. 
The disclaimer rightfully says it is NOT intended to be relied on as a PRIMARY flight instrument, and as its reliability DEPENDS SOLELY the internal gyros of your iPad or iPhone, I wouldn’t say it was a bulletproof backup AHRS. Plus, I did NOT TRY to make it tumble, by performing a very steep turn.
But, if you lost your vacuum in IMC, and needed to get your wings level in a hurry to start a gentle decent from the soup, imho, you would be pretty happy to hav this little app onboard.
It performed as advertised. I’ve been told that iPhone internal gyros do tumble in extreme attitudes, so let the buyer beware.
Personally, I really like this little app, for what it MAY do to save your bacon, when you are out of other options. Just my opinion.

**Developer response:** Thanks a lot for this fair review!

### 5/5 — Excellent Value

*2018-12-09*

Useful cockpit app. Great presentation with altitude, speed heading and attitude all functional. Most useful tool is constant update of nearest airport giving distance, direction and runway info at a glance. Some suggestions:
1) program app so screen doesn’t time out and shut off
2) portrait only - allow landscape 
3) work with open source products such as Stratux AHARS and other ADSB in products

**Developer response:** Thanks a lot! Some improvements coming soon! We just added the German „ADL“ satellite wx receiver that also has an AHRS and i would love to add more devices. For this i need pilots who own these devices, so we can test the integration. Please write via my website www.airwork.biz
Will try to solve the mentioned problems asap!
