Very usable but could be better

This is for the Amplitube for Android not the Samsung Pro App for Android. You will need a iRig UA to use the app.

This free app is for those who have purchase the iRig UA. Using other interfaces will give latency and why the UA was design to deal with latency issues with Android.

Being a free app it doesn't offer as much compared to the iOS versions but then again you are paying for the iOS version. The app is designed for phones and will only display in portrait format and will not display in landscape even on tablets. Which sucks making it less desirable to use in a band rehearsal or a gig because the amp display you have to scroll to access amp controls if you need to do some tweaking. Once dialed in there are 12 presets editable and 3 blank spots for a total of 15 presents you can edit and are easy to switch around in portrait layout if you don't tweak that much and have your sound dialed in for familiar environments.

There is a demo mode sans UA to hear and play around with amps, effects, speakers, mics, and configurations with various guitar styles samples to test drive with. Let your ears decide if this is for you. I was impressed with the sound quality enough to buy the iRig UA (in another review).

Registering the App gives you use of the distortion pedal which I don't understand why not include it straight up. The base amps, effects are useful and you can purchase more effects or amps from the amp via Google Play. You can save money by buying amp or effect bundles reasonably priced. NOTE: Amps or Effects purchased for you iPxx or Computer are not transferable and vise versa. What sucks is unlike iOS or PC/Mac there is not recording (DAW) in the app. (Likely due to Android platform issues) I would be great if you could record (DAW) on the fly even if you have to pay for it.

Using the app with the UA you can on hear using your headphones plugged in to the UA unit and will not play as in demo mode through the phones speakers or ph. headphone jack. This too sucks since it would be great to Bluetooth from the phone to a speaker. Wireless will happen in the next few years whether by ik Media or someone else. When that happens game over for the traditional effects, amps, plethora of cables & power supplies as with Yes does now with iPads and Line 6 (Steve Howe) but with in reach of the common/working musician.

It gets 5 stars for Tone: For a head phone amp it has great tone.

Clean amp is a Fender Blackface Crunch amp is a Vox AC model Lead amp is a Marshall JMC model Metal amp is a Mesa Rectifier model Bass amp is unknown to me since I don't use it. OTHER AMPS you can purchase are FENDER, ORANGE, Jimi Hendrix, Slash, Randal-ish, and Soldano at a reasonable price and save more by buying the bundle packages. I bought the Soldano SLO-100 which sounds great. Maybe there will be Mesa in the future. Some of these amps are only available to Android and not available in iOS. Since these amps are similar to the Amplitube 4 I would say any purchase especially the Orange amps will give any musician a wider palate to work from.

In the words of Michael Soldano about his amps don't change the tubes change the speaker and in line with this you can change out cabinets to any of these amps as well as mics.

Stock effects are not bad either which are more like real pedals than some multi-effect modelers and can be position pre or post amp. You and only use one effect in each category at one time. So ideally you chain could look like this (Overdrive, Amp, Flanger, Delay, Cabinet, and Mic) or a variation there of. You have to scroll/flip to get to each effect and can not be access directly so it is better to use the presets since ik Media has not made a switch board for Android yet. The upside is the is no latency switching between presets.

For a free app it delivers in spades tone wise but the lack of landscape (for access to all amp controls in one screen) or wireless integration merits the 3 star rating. Unlike other headphone amps your phone has more processing power that dated designs of even current headphone amps and you can dial back on the volume on the guitar to cut gain for rhythm and increase the volume for lead and more gain like a regular amp which other amp modelers can not do. The UI is much better due to the screen on your device. Don't have to worry about cheap plastic knobs that can get broken. Install the app to another phone for a lifetime of use. Not have to worry about AA or AAA batteries as much since you phone is rechargeable. Use with the new iRig Duo Pro so you can sing and play guitar for busking or small gatherings.

It would be ideal if you could connect the phone via Bluetooth headphones or speaker and relatively go wireless. The only cables would be from the guitar to UA and UA to phone (clipped to the headstock)
