No speed up any more I purchased this long ago for the speed up functionality and the author removed it on Lollipop. I recognize that he said it was buggy  but it worked fine for me and now this app is worthless unless I maintain an old version. An option to turn it off would have been far more reasonable. I'm also really concerned that he didn't mention this in the app description as well  so unsuspecting buyers will not have the primary functionality he advertises in the app description. Plus no ETA on getting it fixed. Fail.
