Fretbox — Tab Player
Your tabs, offline. No ads.
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Open the Guitar Pro files you already own. Play them back, slow them down, loop the hard bar. No account, no ads, no subscription — and it works with the wifi off.
Fretbox opens the Guitar Pro and MusicXML files you already own, and plays them back properly.
Everything the big tab apps keep behind a subscription is here at no cost: playback, speed control, looping, muting tracks, offline access. No account. No ads. No survey before you are allowed to use it.
OPEN WHAT YOU ALREADY HAVE
Tap a file in Mail, AirDrop or the Files app and it opens here. Guitar Pro 3 through 7, .gpx, and MusicXML. Everything is copied into the app, so it stays with you when the wifi does not.
PRACTISE PROPERLY
• Play at 25, 50, 75 or 100 percent
• Loop the bar that keeps beating you
• Speed trainer — raises the tempo 5 percent every time the loop comes round, up to full speed
• Metronome and count-in
• Mute or solo any track, and learn the guitar part over the band
TUNER INCLUDED
A chromatic tuner with real pitch detection. The microphone runs only while the tuner is open. Nothing is recorded, stored or sent anywhere.
SOMETHING TO PLAY FROM THE START
Four technique exercises written for this app — chromatic warm-up, spider, minor pentatonic, string skipping — plus two public domain pieces.
ONE THING TO BE CLEAR ABOUT
Fretbox has no song catalogue. It plays the files you bring to it. If what you want is a searchable library of a million transcriptions, this is not that app — and we would rather say so here than have you find out after downloading.
