PicDoodle is a great app to have for doodling on the pictures that you take. Add that special message or just draw something funny.
This was my first app for iOS that I wrote in ObjectiveC in 2014.
The inspiration for the app came during a ride under the San Francisco on a BART ride back to our hotel room in Oakland. My son had an entertainment pamphlet and he was doodling on the pictures on the models in the various pictures. I thought then that it would make for a fun app that he could use to take pictures and then doodle on them.
Here are screenshots from when he first used the app after I wrote it.
The app is still available and you can get it here.
