“Really useful app. I’ve been using it to practice some difficult songs and the scrubber feature is so much better than anything else i’ve used. Also the marker feature for looping sections of a song has helped me nail things i struggled with before. Great app.” — Catamaran410

“This is exactly what I was after - allows me to focus on a section of the song Im learning and loop it perfectly so I can get it just right” — Capnlukeron

“Really like this app. Simple to use and very intuitive. I particularly like the loop feature for honing tricky sequences” — Thamagicnumber

Useful but flawed

I was torn between this app and the Anytune app for breaking down and learning some intricate drum beats, I really like being able to set marks and make play lists but the slow down function is all but useless for anything or than slower music with toned down drums.

Also, it'd be nice to be able to set a click track to the songs and set the speed at which you are counted in before a song. For $5.00 I'm a little disappointed with the lack of features this app has. Could be much better

Thanks for the suggestions. We do have more slow-down speeds planned which should help you.

Require a lot of enhancement

The application doesnt allow you to group markers for each songs, all markers are consilidated in one page which become hard to browse. Also setting multiple marker is hard process as each time you set marker for the song, it override the previous one. It should be an easy process to manage your markers.

Also sharing your markers is limited since it allow you to open the file with the app only.

The sound quality of audio file is not clear when you set markers and also when you soow down music.

Also the app should have transport function.

Also the count in should be flixable to have less than 5 count in.

The developer should include a free version which allow you to upload mp3 with limited to 30 seconds and some lock/limited featuresto allow you evaluate the app before the purchase

The idea of the app is great but it require a lot of enhancements.

Developer Response ,

We're sorry you were not satisfied with the app. I'm not quite sure what you mean about the markers - there are only two markers per track and there is no where to list them on a page.

When setting markers, the app tries to do the right thing - set the end or start marker, and then get to the time you want for the other end and set marker again. TIP: you can swipe down on the screen to set a marker at the current time.

Regarding sound quality, we are not aware of any problems here except when using the slow down rate where the current release does not use the highest quality slow-rate playback. Normal rate playback should perfect – what speakers were you using?

That you for your other feature suggestions.

No Slowdowner?! Tempo and Pitch adjustment?

Really nice interface. Better looking than all Apps that offer the option to slow down the music. Add this feature and will be the best for guitar practice. Could become the iRehearse for iPhone. But for now, it's just a nice face for a limited tool.

Developer Response ,

The app does allow you to slow down by tapping the "SLOW" button, but it is limited to one speed in the current release. A future release will increase the range of speed options.
