Sub Buddy - the World's First Attack Disc & TADS Computer on iOS & Android
 

PoutyBatFace Studios proudly presents, your very own...

Sub Buddy!

If you play WW2 Submarine games, or you have an interest in historical mathematical devices, or even want to become a wiz at 'whizz wheels' then Sub Buddy is for you.

With both the most historically accurate digital German U-boat Attack Disc, our unique TADS Computer disc and the brand new 'Visual AoB Helper' tool, you can perform a huge amount of complex calculations incredibly quickly and far faster than with a calculator or a spreadsheet, whether you play US Navy, German U-boats or any other submarine game.

If you always wanted to learn how the 'Attack Disc' worked, but always felt intimidated or confused, don't worry anymore!

Sub Buddy also contains 27 Tutorial Videos that not only explain the overall concepts behind the Attack Disc and the TADS Computer, but also break down virtually every type of calculation you could ever want to learn for your sub-sim gameplay. Within minutes you'll learn how to use these two discs to make intercepting convoys, planning approaches and fast and accurate torpedo solutions with or without the TDC!

Please check out our website for a demonstration video and samples from our Tutorial Video series.

And maybe check out our privacy policy too...it's not very long but we think it's important.

App Requirements:

Sub Buddy fully supports all iOS Devices running iOS 12.0 or newer.

Sub Buddy on Android requires Nougat 7.0.0 or newer.


NOTE: SubSim and Onkel Neal have given us permission to post and cross post. Thank you Neal!

Can confirm! I helped them make the videos etc and I can attest to how much work went into this product. The makers did an outstanding job making the attack disc historically correct down to the last detail, and the TADS Computer slide rule is incredibly versatile and surprisingly quicker than using a calculator in many cases.

More goodies in there too, like the visual AOB helper and the retranslated wartime U-boat Commander’s Handbook!

I don’t share in the proceeds - labor of love for the subject matter!

Thanks derstosstrupp! Your continued support as well as all your training has been so important to us.

I purchased my app right away, I plan on using it and my iPhone as I sim. I have been using the 1 torpedo 1 ship method for some time, and now this as a companion will help with torpedo firing solutions.

"Your" "unique" tool is nothing more but an identical (100%) remake of "Manos Bearing Computer" (https://www.subsim.com/radioroom/sho...d.php?t=235423)

How can you say that this is the "unique" when i firstly created and released, for free, the "Manos Bearing Computer" in 2017 ?

A remake yes but an unique...no! you should have mentioned this at your credits instead of renaming it.

Come on Makman94. No need to post the identical message in all Sub Buddy related threads.

I believe she means it's unique as in it is an app that works on iOS and droid.

The Sub Buddy TADS Computer is unique as it’s the first time, angle, distance and speed disc on mobile devices - and as such doesn’t require the use of any specific PC game or any 3rd party mod. It's also unique amongst other similar discs because it has a second pointer that is used for fast underwater nav plot calculations. The TADS training video 14 shows how that second pointer is used to calculate the turn radius for underwater dead-reckoning navigation, and video 15 also goes on to show the chord length calculation.

The TADS Computer was inspired by discs such as the US Navy “IS-WAS”, multiple circular slide rulers from Silent Hunter 3 mods, makman94's Manos Bearing Computer, and the CRP-5 and E6B flight computer slide rules which Sub Buddy's lead developer has a very long and intimate working knowledge of. As you’re of course aware, the rules, the order and the values are as such because of how the calculations need to work and to maximise accuracy. Whilst no one would ever claim any generic circular slide rule is a world’s first, we feel our TADS Computer is justified in that claim for the two reasons mentioned previously; we are most definitely unique amongst any other digital slide rule.

Thank you makman94 for your support in helping us understand slide rule formulas while Sub Buddy was in development. We have credited you in the in-app credits, as we said we would when you were in communication with us during its development. We also provide a link back to your SubSim profile page for people to check out your own contributions to the community.

Thank you also Pisces for your help with our advanced maths understanding, another person we happily credited in-app!


[Edited 8-Nov-2020 to state makman94's Manos Bearing Computer's full name. The original abbreviation to MBC was an oversight and we did not mean any disrespect. Our apologies to makman94 for this oversight, and thank you for bringing this to our attention.]

Just bought this. Good product. Usable on a small Android phone but someday maybe use it on a tablet.


Currently playing an old-school GUI on GWX called OLC Gold Mk II.



A great old GUI. Although the night scope (which I love, huge on a 34" monitor), does not show the deflection for torpedo angles, (in the real world, the user would take their face away from the eyepiece and look up and see the deflection angle they set for the torpedo, slightly newer scopes would show this when looking in the eyepiece).



OLC Gold Mk II shows it on the attack scope but not the night scope.

So, this smart device product solves that problem (yes I could just briefly look at the attack scope). 90 degree angle shot, 30 knot torpedo, and the disk shows the deflection angle for a shooting solution.

Using the wire method to figure out target speed: works.

Figuring out distance to track based on current target, distance, AOB: works.

Figuring out AOB by target height to length ratio: works.

And a whole bunch of other things.

In short, nice to have for GUI's that might not have a disk already built in.

Just bought it to play UBOAT
 

Hello, everyone. I bought the app a few days ago. Its very ice indeed.

I'm an airline pilot and i figured how to make ILS interception calculations with the TADS computer.

During private pilote courese we have to manipulate a jeppesen slide rule for navigation. But the TADS computer is way more complete.

Cheers.

Oho nice! Zoe’ll appreciate that!

Welcome back!
 

interesting :Kaleun_Applaud: i would love to see how you did that :hmmm: ATPL (finished a couple of months ago) is also what brought me more close to using sub-tools i would ignore previously. the attack disks feels similar to the E6B we used to have to do our calculations too :D general navigation is very similar too, so im in the process of maybe printing some maps on plastified paper so i can plop my routes using my beloved CP-RLX plotter
Clear skies and Good hunting keleun! :Kaleun_Salute:

Sure! Here it goes.


Lets say you are going to intercept at the IF (intermediate fix) at 10 nm from the threshold and at an angle of 70 degrees.

Align the 10 of the speed scale (in this case the speed scale will act as distance) with the 70 of the degree scale.


Now heres the part that you have to have a previus knowledge of turn radius.

If you are flying at about 180kt ground speed, your turn radius is about 1nm.


Just look for 1 in the speed scale and read opposite to it the degrees, in relation to the final approach course, you have to start turning to be stablished on the localizer.

You can also do it with a calculator.

Arctan of turn radius / distance of intercept



If you are interested in mental math for pulots i would suggest the excellent book "M3 - The mile, The Mach, The minute" from Mike Roumens.
