I Found this app very useful as I led up to my start date and for the following month. At some point, during an update, everything that I had entered - diary entries, mission notes, even quit date - was erased. It made it very difficult for me to continue, as I felt like I lost my real life progress. I went back through the missions and filled out what I could remember, and kept going forward, but then I purchase a new iPhone, and the iCloud back up does not save the data from this app, so once again I had to re-do everything. Of course after the next update I had to start all over yet again. So good app for the first month, but I am a year now and can say that this app cannot be relied on long-term.
