I bought this app for my iPhone and iPad. Used it for about 3 hours on my iPad while in a meeting but uninstalled due to the number of crashes. I like the program and the way it is designed more than others I have tried but I cannot rely on it as an effective email solution unfortunately. Airmail developers, let me know if you get the app fixed and I will be happy to try it again, especially as I gave you money for it but as it currently works, I cannot use it.
