Check out the 'Developer Website' link for a 3 1/2 minute promotional video! Sub Buddy brings the most realistic and accurate digital German U-boat Attack Disc to life and, for the first time, to hand-held devices so you can use it just like a real slide-rule! We've designed a unique circular slide rule called the 'TADS Computer' and together the two discs will allow any player of WW2 Submarine games to perform calculations and complex torpedo solutions faster than a calculator or a spreadsheet. It doesn't matter whether you sail US Navy Fleet boats, or German U-Boats, whether you are a lone Silent Hunter, or you play as part of a Wolfpack, these realistic and powerful tools will allow you to become one of the best Aces of the Deep! To help you, we've created 27 unique Training Videos, one for each specific task or operation, so you can easily and quickly learn the immense power these discs provide. To make this as responsive as possible, especially in the heat of battle, we've chosen to bundle all 27 videos right into the app! That means you never have to worry about Wi-Fi or data signals, lag or streaming and you can cram in a quick refresher or learn a new technique on the tube, waiting for a taxi or in the queue at the Post Office; so you can always get the information you need (with Picture in Picture on Apple iPad, so you can follow along) right when you need it! This does mean that the app is 1.32GB in size, so make sure you are on Wi-Fi before you begin your download. Another unique feature is our 'Visual AoB Helper' - or 'Angle on Bow' helper - that you can use to visually replicate what you see in game and get an accurate AoB reading to within a single degree! We also allow you to change the time of day and weather so you can best match the conditions in-game! Yet another unique feature, is that we have designed this app, from the very beginning, to fit you, the user, the best way possible. We support Left and Right handed modes, with all the primary buttons available comfortably within the sweep of your dominant thumb, as well as the ability to dynamically re-order the menu system to put what you need, where you need it most; and these settings are always automatically saved and changeable at any time without having to find buried settings or options. We sincerely hope you love these discs as much as we do and believe us, once you become skilled in their use, you will be able to do almost any calculation with them - ‘submarine sim’ or even real life - so quickly you'll amaze your friends and fellow players.

NOTE: Touch markers on the videos are only there for demonstration purposes only. They are not in the actual app.
