What is the BEST way to go for a smart phone artificial horizon app?
 

I'm currently leaning toward--

IxGyro ixGyro - the true-attitude indicating glass cockpit app

Here is a list of phones they've tested it on (maybe an old list):
Google Nexus S (Samsung Nexus S i9023)
Samsung Galaxy Tab
Samsung Galaxy S2
Google/Samsung Galaxy Nexus
HTC Evo 3D

If I want to run it on my current phone I'll have to augment it with this device to provide the needed 3-d rotation rate sensors: AHRS G mini

Some comments on the IxGyro website suggest that the Levil plug-in device will provide some advantage even with a newer/ higher-end smartphone that possesses 3-axis gyros as well as 3-axis linear accelerometers

Don't worry, I won't rely too much on it. Most of my blind flying is partial-panel and I'm pretty comfortable with that, I just want something that has some significant chance of giving me extra help if things get too loosey-goosey in extreme turbulence. I'll have freshly packed parachute also.

Any links to other appropriate forums where this is being discussed, would also be welcome.

Why are you deliberately setting off and flying partial panel in the first place? Are you in a glider?

Install an Ilevil AHARS gyro unit, plumb it into the pitot static system, wire it into main aircraft power, and off you go, you get 3 axis digital gyro, magnetic compass, and pressure altitude and airspeed, then it transmits over a adhoc wifi network, connect to it with smartphone or ipad, off you go. :ok:

I wonder myself. The Galaxy Ace (Which passed my good phone test by not exasperating me to the point of a club hammer test and surviving immersion,) doesn't behave in the air as it hasn't got gyros but a friend has an S2 which seems to work ok. I would envisage a use for it in VFR when crossing the channel, should the haze make the horizon indistinct together with a beady eye on the altimeter and slip ball, naturally.

Surely this can't be real? You're not seriously using a phone as your main reference for flying in IMC are you?

I'm not getting many answers back from the Levil or IxGyro folks. Will post more when if I hear some replies that shed some light on this.

"Surely this can't be real? You're not seriously using a phone as your main reference for flying in IMC are you?"

No, it's just an extra. I rely mainly on this via standard partial-panel techniques: Turn Rate Indicator
