This app is informative and interesting. Useful for insurance adjusters, roofers, construction, etc. Has lots of different options so click on everything to see what all it does. This is the app to have if you need to keep up with storm damage for your job! I have had no problems or crashes with iDamage. The alerts I selected come through every time (you must of course have an Internet connection.) I use it on my iPad 2 and my iPod 4th generation. The developers for this app are doing a great job, keep it up!
