Now it’s hard to know where the buttons are. Also, the rating is too much on the screen. I can select the song I want to play, but I can’t change the speed. Not sure what’s going on. ### 1/5 — Will not work on my iPhone 12 *2021-01-14, version 2.3.2* Nothing happens when I tap on select track, despite trying in every which way. No way from app to reach customer service. ### 4/5 — Awesome!!! *2019-07-25, version 2.3* This app is a game changer. It was recommended to me by a fellow musician and I am NOT disappointed. But a few things. You cannot pause the music when your phone closes. Which happens because you are listening/playing music. If you could pause it then go back 15 seconds or something when your phone closes then I would give it 5 stars. But overall this is money well spent. ### 5/5 — Five stars even with its faults *2017-12-17, version 2.2.1* The interface could be improved but it still deserves five stars just because it is so extremely useful. For trying to work out complex ornamentation in baroque harpsichord works this is indispensable. ### 1/5 — Unable to get registered *2016-03-14, version 2.0.3* I have just purchased the app but after 6 attempts I am still unable to get registered. There is no indication what the problem is but I am unable to use it! ### 4/5 — Good but could be better *2015-11-08, version 2.0.3* As a new violin student, this app has tremendous potential! However, it appears to work best with my newer iPad, as opposed to my original. Problems with my screen freezing up have resolved when used w/iPad4. C Although this app would be improved with clearer "first time" user instructions, I use it successfully now everyday during my practices. ### 2/5 — Upgrade and improve speed shifter!!! *2015-07-31, version 2.0.3* I don't know if I'll get s response but this app needs to improve on a few small issues! Tech support please respond! This app is a good app, but the speed control needs to be improved! It is not so user friendly when adjusting in the settings down to slow. Some tunes I need slowed down to 30bpm to learn tunes. The button to slow down tunes, does not adjust that easily to get down to 30bmp. Please upgrade this app to slower speeds, with simple instructions! + add the bagpipes practice chanter would be nice. Thanks ### 1/5 — SpeedShifter *2015-06-21, version 2.0.3* Where are there any comprehensible instructions??? ### 5/5 — Speedshifter for iPad and iPhone *2013-07-15, version 1.0.1* I have used Speedshifter in all capacities: as a teacher, a student, a performer, and just a back porch fiddler. It is one of my absolutely most favorite tools, but it meant dragging a laptop around with me, but not any longer. I just downloaded the mobile Speedshifter to my ipad and it defaults to my iTunes music list. How sweet is that! Nice work y'all. I am just delighted. Thank you.
