iPhones were the only devices that had a microphone built-in at the time of initial release. While newer iPods do support a microphone we thought this may confuse some people. We wouldn't want people buying an app that has features that their device does not support. So we thought it was best to split it into two separate versions.
We do have plans for additional sound effects in the future. Whether these could replace current ones or get added in with the current set is up in the air. However, as long as there is spare room on the soundboard there will be effects to fill it. Keep your eyes peeled for updates.
One feature we would really like to see in a future release is the ability to record the soundtracks made on the soundboard. These could be played back at later times or even shared with friends. Another feature we would like to incorporate is the ability to use the video camera to catch victims reactions when scared by the sound activated scare.
The soundboard is not meant to play all of the sounds at one time. For one it's just bad form, you can't decipher all of the different effects. Another reason is that they can eat up your device's memory.
