Tap-It is an iOS app designed to accurately capture tap timings for experimental auditory research. It plays an audio .wav file, to which user tap responses are synchronized. Both the timestamp of the tap on the screen and the recording of the sound of the taps (using the microphone) are captured. Tap-It uses MoMu and STK:MoMu Release. Tap-It works on iPhone (3GS or later) and iPod Touch (4th gen. or later).
Features
Mobility - Because it runs on handheld mobile devices, Tap-It allows tapping responses to auditory stimuli to be collected under a variety of conditions (while walking, for example).
High-Precision Timing - Tap times are synched to the start of the audio file being played. Tap times are recorded using the touchscreen. Additionally, an audio recording of the tap responses is created, which can be used for even higher timing precision.
Touchscreen - The flat touchscreen of the mobile device eliminates tactile and auditory feedback experienced when using a button, computer keyboard, or mouse for collection of tap response data.

Announcement
Thank you to everyone who visited our poster at ICMPC in Thessaloniki!
We appreciate all the feedback and suggestions, and will be updating the website soon.
We would like to clarify one point about the latency of the audio recordings.
The latency is actually the length of two buffers. This is not zero latency, but a negligible constant latency.
Please see the proceedings paper for details. Sorry for the confusion!
