## CarlTune Reviews in United States

### ****- "DadGad"
DadGad is EACEAE
-- 1234Mars4321, 2025-01-10

### ***** "Five stars!"
Extremely helpful. Glad I purchased. Helps greatly with everything especially for practicing vocal slides.
-- Bsh009, 2024-05-03

### ***-- "Ok"
Lived the app but had to delete. Constantly get stuck on ads and it got old fast. Good luck
-- JabbaTheSloot, 2024-02-22

### *---- "Ad removes by google"
What is it? After 3 time of using can not open...
-- Natalie_M189, 2022-12-17

### ***** "Perfect for flute and bansuri learners"
This is an amazing app if you are learning Indian bansuri or western flute or violin. This app is perfect since it reads notes in Hindustani Classical notations. I don’t use this app for tuning but to make sure my bansuri notes are correct. Creator of this app should consider allowing export (email or notes) of notes played which will allow to check incorrectly  played notes.
-- Prashant , 2021-11-13

### ***-- "Doesn’t work for vocals"
I bought this after watching Dr Dan on YouTube extoll its virtues for checking your voice pitch but it doesn’t work for me. I’m singing long whole notes (background aahhs for example) and the app doesn’t even come close to the note I’m singing. However when I pluck the same note on my guitar it reads it well. I don’t need another guitar tuner though. Weird. Perhaps some voices have too much nuance.
Disappointing after seeing it work with Dr Dan.
-- Nicco Badinov, 2021-03-05

### ***** "Spectacular!"
This is the perfect tuning app. If you have had lots of music in your past, if you have had music theory or if you just want you instrument to be in tune- perfectly, btw- then this is the app you need.
I have one other that works similarly and is specific for a guitar (it shows a green light when it is within a certain range of pitch) but this one is perfect for my ukulele.
-- jlafunk, 2013-07-21

### *---- "Not compatible with 3rd generation iPod Touch"
Application does not work on an iPod Touch 3rd generation as stated.  3rd generation will not upgrade to iOS 6.1, to which app is limited.
-- Idaho_karen, 2013-06-13
