Judo V2

The goal of Judo V2 is to manage both the time and the scores of a Judo contest. This app is therefore dedicated to people familiar with this sport, and knowing its rules.

The V2 brings a brand new interface and the support of retina displays, works in portrait or lanscape, and helps clubs with a new randori mode. As usual with my apps, there is no Judo and Judo HD, just a single universal app.

As this app works the same way on any iOS device, the screenshots will mostly be captured on an iPhone

Competition

iPhone version, portrait mode

iPhone version, landscape mode

iPad version, landscape mode

The user may want to type the contestants names, but that’s not mandatory.

Then, if he wants to change the timers, he must push this button:

This opens the following screen:

The default contest time is five minutes, and the osaekomi time is twenty seconds.

To begin the contest, just push the Hajime button, and the timer starts.

When the timer is started, the Hajime button becomes a Mate button. Just press it to stop the contest.

The flip buttons under the I, W and Y letters allows to handle the points for each of the contestants. To add a point,  tap on a flip button, or slide the finger from the bottom to the top. Sliding the finger in the opposite direction, from the top to the bottom, allows to cancel a point.

In this screen, White have scored a Yuko, and Blue have scored a Waza-ari. Of course, the app will stop the timers and display the name (or the color) of the winner if one ipon or two waza-ari are scored.

Again, sliding the finger from the top to the bottom of the Ipon flip button will cancel it.

Pushing the Soremade button will reset the app for the next contest.

When the user pushes the Mate button, two “Shido” buttons appears, allowing to handle the penalties. Each Shido displays a box near the flip counters.

Except for the first shido (the yellow one),  the app automatically assigns the corresponding points to the other judoka. To cancel a shido, slide the finger on the shido boxes, from right to left.

Pushing the Osaekomi buttons available in Hajime mode starts a new timer, for the osaekomi time.

In the screenshot above, White is submitting Blue for four seconds : the left osaekomi button has been pressed. If Blue is able to get out from the submission, the Toketa button must be pressed. If the roles are inverted, you don’t have to press the Toketa button : press the other Osaekomi button instead. As the time flows, the app assigns the relevant points. Of course, at the end of the configured time, the contest stops and the victory is awarded.

In the event of a tie, the app allows to award a victory by decision (by clicking the white or blue button), or declare Hiki-Wake.

Randori

One of the new features of Judo V2 is the Randori mode. To access this mode, press this button:

The competition screen slides out and the new Randori screen slides in:

This mode allows to manage a series of randori and rest phases. To configure this, press this button:

which displays the following screen:

If you want to get five randori of four mintes each, with three minutes of rest, configure judo as shown bellow:

Then, press the Hajime button to start the first randori:

When the randori ends, a bell sounds and the rest timer is initiated. Rest time is displayed in green to avoid any confusion with randori time.

When the rest time is over, the bell sounds again and the second randori starts, and so on until the last cycle is reached.

Settings

To change the app settings, press the “Settings” button in the right upper corner of the screen.

The “Arbitration with kokas” switch, which is disabled by default, will allow kokas in the contest.

The “Play sounds” switch is used to decide whether a sound is emitted by the software when the fight (or randori) is completed. The default sound is a bell, but the user can replace it with any sound. To do this, connect the iPhone / iPod Touch / iPad to the computer, launch iTunes, choose your iPhone / iPod Touch / iPad in the left panel, and click on the “Apps” tab on the right. At the bottom of the screen you should see an “Exchange” section.  Judo V2 should appear in the list, click on it. On the right, the “Add …” allow to add files: Click to add a sound, which must absolutely be AIF or WAV format, and not exceed 10 seconds. Click the “Apply” button at the bottom right of the iTunes window.

In judo, the first contestand is recognizable by its blue kimono, or its red belt.  The buttons below the text “The first contestant  is …” allows to color the text of the counters according to that color. Since the beginning of this documentation, the first fighter is blue, let’s choose red:

The last switch, “Tint counters” tint the counters with the color we chose for the first fighter. Let’s stick with red:

Scoreboard – Connection to a television or to a Apple TV

Judo V2 can turn your iPhone / iPod Touch / iPad into a real scoreboard controller. This option is not free and can be purchased by pressing the “Settings” button,  then taping the “Scoreboard” tab, and finally pressing the button with the price. You will be asked, as for any in app purchase, to enter your username and passwords iTunes. For more information about in app purchase, please visit this page at Apple’s.

Once the purchase is complete, the screen turns into this:

For now, press the OK button to return to the main screen. It changed:

A white square is now displayed in the White and Blue text boxes , and two additional buttons appeared next to the button of the timer.

For now, we will connect our device to a television. You will need a video cable that connects to the “dock connector” on your device. At Apple, this may be:

• a digital AV adapter if you own an HDTV
• a Composite AV Cable or
• a Component AV Cable if you have a traditional TV.

Of course, other manufacturers offer similar cables (Update : be careful, some cables might not be this compatible…).

It is even possible, with an iPhone 4S or a iPad 2, to use an Apple TV and AirPlay. To do so, press twice on the ‘Home’ button of the device (the round button below the screen) to bring up the taskbar. Swipe right on the taskbar to display the control bar :

 

Tap the Airplay button, then tap the name of your Apple TV. Toggle the “Mirroring” on/off slider to ON:

Voilà! To disconnect, tap the name of your device (“iPad” in the screen above). For more informations: Apple TV: How to use AirPlay Mirroring

Once the cable is plugged into both the device an the television, or using AirPlay, this picture will appear on the latter:

Meanwhile, a message appears on the iPhone / iPod Touch / iPad:

Now, all actions performed in Judo V2 will appear on the television.

At first, there isn’t much informations to display on the television. Let’s add the judokas names.

Then we will add their nationality. To do this, press the small white square at the left of the names of the two judokas. This opens the flags screen:

Choose the flag, or press the button “No flag” if you do not want any. Just like the bell sound, you can add pictures via iTunes, if you want to add some clubs logos, for example. Pictures must be JPEG or PNG.

We also have to display the weight class. To do this, press this button:

This opens the following screen:

Scroll the graduated bar to select the category, if necessary by pressing the buttons – and + side to choose if the weight is below or above, or press a button at the bottom: the first group of buttons contains the female categories, the second the male categories. Press OK.

Scoreboard – Wireless connection between iOS devices

There is another way to manage a scoreboard, by using two iOS devices. Judo V2 must be installed on both devices, and the “Scoreboard” option must have been purchase on both devices, although only the first purchase will be charged. In the example that follows, we will assume that the controller is an iPhone, and the scoreboard an iPad, but all the combinations are possible.

The iPhone does not require more configuration than if it were connected to a TV. We always need to type the name of the judokas, choose their nationality and their weight class.

On the iPad, however, an option must be enabled. Press the “Settings” button and then tap the “Scoreboard” tab, finally, turn the “Scoreboard” switch on.

Press the “OK” button. The iPad is ready to be controlled by the iPhone. On the latter, on the main screen, press the following button:

The display of the button lights up, and the following information appears:

If the iPad is found, a second message appears:

Otherwise the failure message is shown, and the screen on the button turns off:

Communications between the iPhone and iPad use Bluetooth, if it is active on both machines, otherwise WiFi is used. Bluetooth works better, and faster.

If more controller / scoreboard couples are used in the same room, interferences may occur. The purpose of the “Transmission channel” in the Settings screen is to avoid such interferences: assign a different channel for each couple.

I hope you’ll like this app. Thank you to Jean-Claude, Hélène and Abel for their great ideas. A huge thank you to Marc for his tests and ideas.
