Have you heard of Stikbots? They are these mini plastic stick figures with suction cup hands and feet. They come in all different colors. You can even get Stikpets, which are different kinds of dogs, cats, and even monkeys! If you have ever heard of the YouTube channel called "Stikbot Central" and you want your Stikbots to move without your hands in the way, this app is perfect!
OSnap! works like this: You take a picture of your Stikbots doing something. Let's say they are sitting down. Then you take a picture. After the pic, you move them a little bit and take another picture. You should have about 30 pictures (at least). The app keeps track of how many pictures you have taken.
Say you watch the video you created, but you want to add talking in it. Click the microphone and tap record. It plays the video for you and you just talk.
The app is free, but you will want to pay for upgrades (voice over, ability to share and send your video)... that will run you about $3.99.
