### 5/5 — iFretless Apps open up a whole new world of Instruments + MIDI for Guitarists and Bassists!

*2025-02-26*

Each iFretless app gives you the ability to play countless lead instruments (Brass, Horns, Guitar, Bass or ANY MIDI instrument) - All without having to learn keyboard!
 
The sounds built into these apps are top notch! The flexibility to setup the number of frets and strings and the note offset between strings is a game-changer! 
 
Do you want to instantly apply your skills as a bassist or guitarist to ANY instrument? Would you like to perform a sax or trumpet solo from your virtual bass on the screen?  Easy/peasy! 
 
Do you just want to play along with some tunes while you on the move? Piece of cake! 
 
Would you like to play a local or remote synthesizer from your familiar fretboard instrument? This is an essential app to help make that happen!
 
I’ve wait for an instrument app like this for YEARS!  
For the lowest possible latency use wired headphones (but it works with Bluetooth headphones as well).
 
Just TRY it!

### 4/5 — Please test and release these as real Audio Units for desktop.

*2023-12-13*

Could really use these on macOS. Thanks.

### 3/5 — Ayuda

*2020-11-26, version 4.0.10*

Acabo de comprar la aplicación para iOS auv3 y La barra de aplicación de GarageBand me sale en el lateral derecho y es muy difícil poder escuchar y poder grabar ,me pueden ayudar.

### 1/5 — Constant crashes

*2020-05-21*

Its never stable in Cubabsis.Youve got a 50/50 chance if it even loads letmalone records.

**Developer response:** We can fix this if you send us a list of steps to reproduce the crash. Please contact us via the support form on out website: http://bluemangoo.com/contact_us.php thank you.

### 5/5 — A new sound and method to which I make music

*2019-10-13*

I already wrote a review on the Saxophone version for the iFretless apps. As amazing as the saxophone one is, I like the sound of this one even better. Just as easy to use and with so many ways to sculpt the sound just how I want. This app adds a whole new dimensions to my music making. The best part is it's all on the phone. This app works amazing when combined with the Korg plugKey. Just plug it into your phone and then stereo quarter inch cables to any speaker system and you've got yourself a beautiful sound you will be addicted to playing and listening to.

### 5/5 — A brass suite at your fingers...

*2019-06-18, version 3.6.7*

For a guitarist like me it’s like a little dream come true. Play brass with a “guitar like” interface. Veeery nice sounds, dynamics and aftertouch. Very fun to play. Great.

### 5/5 — Developer continues to update

*2019-01-29*

To make for a great ever improving playing experience! If they add an option to include fret noises on their iFretless bass and guitar app, they would’ve successfully created the best software for emulating guitar expressiveness!!! Get the entire iFretless bundle and express on👍🏾👍🏾👍🏾👍🏾...please add a subtle fret noise option. You guys are amazing!

### 4/5 — In app video does not play

*2018-10-22*

I had to go to to the app support web site because the in app video you can access after pressing the question mark does not play. Aside from that the brass sounds are very realistic. I will have to get used to playing it like some kind of string instrument, I guess. Not sure how.

### 5/5 — No reviews? Really, Apple?

*2018-03-04*

This may not get as much coverage as the Bass and Sax versions, but it is a beautiful sounding and looking virtual instrument. The sounds are silky and have a gorgeous eeriness either stand alone or added into mixes. Because of the playing dynamics and harmonic visualizations being so accessible and possible, the iFretless apps are as exciting and fun to play as anything I have on the desktop...including the instruments in NI.

### 1/5 — Do not spend any money on this!

*2017-06-30*

Could be a nice app, but the “user support” is a real nightmare.
One of the last updates messed up the app completely: audio output of the device will be muted as soon as you start this app. Only a restart of the device will bring audio output back.
I have contacted the support and asked them to fix this. They didn’t even bother to apologize and told me straight away that they will not fix it for some (obviously made up) reasons. End of discussion.
This is the most rude and unprofessional “support” I have ever encountered. Note that they still claim support for iOS7 even though they know that this is not true...
