This update to FourChords Guitar Karaoke comes with huge improvements, including a shining new user interface which brings playing songs in the center of the action and the much requested playlist feature.
Here’s what’s new:
+ PLAYLISTS - Add and arrange songs into a playlist that you can play in one go. This is perfect for practising for performances and even for playing live troubadour sets with FourChords as your backing band.
+ SELF-ASSESMENT - Playing songs well with your guitar takes practice and we want you to be able to track your skill improvement over time. With the new self-assessment feature you can now rate how well you played each song, which makes it easy for you to track which songs need most practice.
+ NEW LOOK - Our new design is focused on playing songs while giving you lightning fast access features you need, like the tuner, profile and guitar lessons by Justin Guitar.
Here’s what’s gone:
- BADGES, DAILY GOALS AND STREAKS - Our XP-based level-up feature and new self-assesment functionality are much better ways to track your progress than our old badges, daily goals and streaks. Some you may miss those, but we needed to make room for the new features to keep the app clean and fun to use.

MrSammyboy,
Great way to learn guitar
Update: app goes into “updating songs“ mode multiple times per day. Usually in the middle of a song. Often it takes 3-5 minutes. Is really irritating. Getting the strong sense app is doing much more than “updating songs”. App only allows you to create 1 playlist. Rearranging songs in that 1 playlist is a haste the larger it gets.
App is good for a true beginner but you’ll want to migrate to other apps that offer more flexibility and options soon.
I love this app. There isn’t a better way to learn. I’ve been using if for about a month but it recently started acting buggy. Seems to hiccup a bit ( not when I’m receiving email or text). Also, stats for number of songs played doesn’t count properly. Closing and opening program doesn’t ‘reset’ it and only sometimes does turning the iPad off/on work. Lastly, noticed that the score for some songs show a chord that isn’t even in the song and docks you 200 points for not playing it. Please fix the bugs - then it is a 5 star app.

lefty63w,
Beginner has learned a lot
Has selection for rhythm parameters with an excellent how-to for chord construction and strumming. New songs added that provide chord and strumming variations across the group of songs. Also songs have lyrics if you’re talented enough to play and sing (I am not, at least for right now).
So far I his app has provided me with a platform to learn, the play and practice songs using basic chords, adjusting tempo and backing up to replay a section as needed. I like that it can be done with just a touch or swipe of my finger on the screen.
From the library of songs available I’ve built my own playlist of songs for learning and practice. As new songs are posted it’s easy to add them or later delete from the playlist.
As someone who previously had not spent a lot of time with an acoustic guitar, I find this app useful and worth the money.
What I haven’t tried yet is setting up a progress sharing account (mic on you device set to On) so I could receive “a more tailored user experience, song recommendations and playing tips”. Wanted to get my basics first so may try it, now that I’m more comfortable with my playing ability.

Jeffreaka,
Great app
Wonderful app! I’ve been using it for several years and it keeps me very busy always working on songs I actually really want to play! I’ve been playing for many years so just following along (I turn the volume on the app down all the way) and just play and learn new songs on my playlist (about 800 songs I have on my playlist) so I never get bored with what I’m playing. The chord boxes let you know what chords to play and the lyrics are included. You can slow songs down as you are learning them and increase the tempo as you become more comfortable! You are able, on some songs, to transpose to a different key, which I love for singing in a key in my range! It also has a tuner and lots of videos for beginners as well as strumming patterns with each song. I highly recommend this app for anyone, beginner to advanced players!
Rick N P,
This is an awesome app
For someone who has only been playing guitar for six months, this app, coupled with The Justin Guitar app, has taught me a huge amount. I can play about 15 or so cords and have learned about dozen strumming patterns. While it might not be an app for accomplished players (I don’t really know) this is precisely what a less accomplished player needs. It is super important to be able to have fun while learning and the Hal Leonard traditional method wasn’t for me an adult. This app makes it fun to learn and to practice. Just a great idea and so worth the money! This is a must get app for anyone serious about improving. I love it! I’m 56, and have a Martin D-28, a Art & Luther Cedar, a Fender PM-TE travel guitar and a Fender Tele. This app has given me the gift of being able to play respectfully within a few short months and I look forward to learning more from it. Can’t want enough good things about it.
Easilytaken,
Great way to learn simple versions of songs but ....
With the new update I lost full access to all but a few of the songs that I’ve previously had access to for years. I believe I probably paid at some point to access the songs that I am now unable to access because of the update. If I remember correctly, I was a VIP customer before the update.
Update: The software developer responded immediately and brought me up to speed on my status. My subscription had lapsed, so losing access was a “bad” on my part for not renewing. It was just a coincidence that an application update occurred at about the same time that my subscription expired. I owe Musopia an apology and have correspondingly adjusted the star rating upward by two stars.
The app is very good for learning strumming patterns, chords, chord changes, etc. I particularly like that the tempo of songs can be adjusted faster or slower as you are learning. Also, the catalog of songs available is very large. Some talented people have put a lot of work into developing this application. Well worth renewing my qsubscription.
Thank you.

Scarcraig,
Great Value!
After spending hundreds on private lessons I stumbled on Four Chords. This is without a doubt the best beginners resource available. Worth the very reasonable price! They're adding new songs almost daily, and it's really a lot of fun to play and practice. I don't dread the hours spent practicing anymore.
Try this app you won't be disappointed. The chord recognition piece doesn't work very well, but even without it it's still a very well thought out solution to learning chords and transitions.
You will learn chords faster and better using this app, and as a bonus, you'll have a lot of fun too!

Air Blackstone,
Fun App but Glitchy
You can look at the other reviews for what is likable about the app, so I won’t duplicate those praises.
The biggest problem with this app is that it glitches on a regular basis. One of the most important thing as a beginner needs to work on is their timing. But this Apple often mess up on the downbeat advancing about a half a bar which will totally messed with your time. This is very frustrating and should easily be fixed by the developers.
The other major shortcoming is trying to figure out strumming patterns that go with songs. You can easily start to think that you’re a better player than you really are because of the backing tracks.
The interface is pretty sluggish changing from one Menya to another. Also the songs should remember what tempo you’ve been playing out. So for example knocking on heavens door is 74 BPM, but if you’re learning it at 59 BPM, the app won’t save what speed you’re trying to master. It resets to 74 ppm every time. Likewise there’s no tracking of your progress at any particular BPM. That would be a super simple feature to implement.
There’s a microphone icon which I guess is supposed to allow you to record, but it doesn’t work.

howly hunter,
That’s the way
At first I was like what’s this I can’t keep up with the chords but later after practicing I found it got easier and easier I hope to start singing along while playing the guitar with the tracks lots of good choices too ain’t even a song suggestion my rating is superb now if I could just master yousician
Well it’s been several months since I subscribed I haven’t used as much but I wish you could make a bass guitar program.

Big Daddy 102,
Makes practicing and playing more fun
As a beginner, this apps makes learning new songs fun. I highly recommend it for beginners and maybe intermediate players. It’s easier to learn the song with the beat and melody going with you. Worth the money to me.
Update. It’s been a year since last update. Still using and liking the app but have some improvements it needs. The major one is editing the play list. Adding and removing is all good but you have to move each song line by line to change the order. I.E. if I add a new song, it’s at the bottom of playlist. If your list is 40 songs long, and you want it at the top, you have to hit the move button 40 times.
2nd update. 2 years since the last update. It’s looking like what you see is all they’ll be. Still liking and using the app but it could be so much more.
3rd update. Still no app updates or bug fixes. It’s been several months since they’ve added any new songs and customer support has quit responding. Looks like they are abandoning it. I won’t be renewing my subscription

lookingforsteeldrumapp,
This app crashes on older IPads.
I have used and enjoyed this app for almost two years. Now it however crashes and is not useable on my first generation I Pad and my older I Pad mini. It used to run fine on them. I was told that recent enhancements such as tracking {no use for that at all} made this happen. I do have an I Pad pro now that it runs fine on but I prefer to use it as a midi controller using Sample Tank etc. and not have to tie it up running the 4 chord app. If you have an older Apple device this app will not work well. This is a known problem for them but they have not made it a priority to fix it.
