- The app that runs it is not necessary and thankfully, as it didnt work on my iPhone for about a week (wouldnt connect to the speaker through the app). It might work better if they add more tape to both sides past the screw holes. Great concept and saves space. I love Adidas. It is an easy book to read,and while it deals with complex issues, I never felt overwhelmed by them. The instructions were in a different language. Replacement headphones stopped working after about two months. This gave us so much more room to hang our clothes up - two rods on each side. Ive never had a Dearfoam do that so quickly. Not as good quality as I was expecting.
