What's a good app on iPhone to track your baby movements and kick?

Baby center app free

I keep two, ImExpecting app is great. Has a great symptoms & baby kicks calendar, q & a segment and more. Completely free. Gives you weekly baby development info, tracks your symptoms and weight as well. Cute "how big is my baby" widgets too.
Also try babybump by alt12, Allows you to connect with other expecting moms, has a belly pic organizer, and journal. Also has day by day developmental tracker, including just for dad tips. Comes with countdown but most apps do, and you can buy more features for it but not essential, basics are nice anyway.
These are the best free apps i've found, just remember development trackers are general and are specific to basic pregnancy, all are different. Best of luck hope this helps!
