Kick counter app

Johanna
Hey, can anyone recommend an iPhone app for a kick counter where I can just add kicks throughout the day, rather than having to have a session running for an hour?
I'd like something that keeps a diary so that I can see if baby is more active in the morning or at certain times of the day. 
Every app I've looked at so far just shows me total kicks for the day, or you have to start running it for a specific amount of time.
