Reaction time delayed, how about making it so when your thumb is on the shaker it does like a 3 or 5 shake beat. Different shake tones too.
Shaker itself was okay with changed settings and practice, but why access to personal info, contacts, etc.? Creepy; uninstalled. I wanted for music!
Works much better if you change the default settings. Most importantly, move loudness down so that you have to shake it harder for the louder effects
Good for making lots of noise. Impossible as an actual shaker. The shaking barely correlates with the sound.
Not useful for music. And why does it need access to my contacts?!
Why does an acustic shaker need access to my contacts list and the phone? Access to internet i get, you want to track users. But personal info?
