went with my sister to check out a house for purchase. she took out her galaxy note 2, took a picture of one of the rooms and after measuring it. she took out her note 2 s-pen to write directly on the picture she just took, drawing lines and writing down measurements. and man that was useful. this is samsung' proprietary software that comes with the phone. now is there any app like this for Android? i don't want to add notes or bubble text to the picture, i want to freely write or draw whatever i want on the picture i took. any program similar to this that would let me do this with my finger?
