User's guide

The Silent presentation timer is the most discreet presentation timer ever designer. Just keep the phone in your pocket and let be guided by unobtrusive vibrations indicating the phases of the presentation!

I have been using the timer during my own presentations and developing based on my own experience with presentations and meetings.

Just four easy steps

1. Setup the presentation length, alarm timing, and vibrations.
   • Orange alert - "more than half is gone", timer displayed in orange. The phone will also vibrate once ("-") to indicate beginning of the orange interval.
   • Red alert - "the end is near", timer is displayed in red color. The phone will also vibrate twice ("- -") to indicate beginning of the red interval.
   • Presentation length - perhaps no need for explanation, here:-)? The phone will vibrate thrice ("- - -") to indicate the end of the presentation.
   • Configure the rest - e.g., if you would like to see elapsing time, then disable sleep mode and enable screen dimming to save the battery.
2. Start the timer.
   BTW: If you do not like the notification sound, see Tips and Tricks how to get rid of it.
3. Put the timer in your pocket - or, if you would like to see elapsing time, keep it on the table. If you want to keep the phone in the pocket, I recommend to rehearse it first, not all pockets are suitable - if it is too slack (or sometimes too tight), you will not feel the vibrations.
4. ENJOY YOUR PRESENTATION!

Changing Configuration When The Timer Runs

If you change the settings, some of the options will apply on the fly even if the timer is running; the remaining settings are applied only if stop it and run it again. See the Feature Matrix.

Wear timer

Control of the Wear timer is nearly the same as of the phone timer. However, on Wear you have some additional functions available.

Lock Stop

Using the timer on the Wear device I frequently experienced an unwanted stops of the timer just by accidental touching the wear device. To avoid unwanted stops I implemented a special LockStop mode. Since not everyone must necessarily love this feature, LockStop mode can be enabled or disabled in the Settings.

• When disabled, pressing Stop button just stops the timer, Pause button pauses the timer. This is the default state.
• When enabled, you have to touch the Wear screen twice to stop or pause the timer. After the first tapping the Stop button, the buttons change and a new Stop button is displayed. At this moment you either tap this second Stop button which stops the timer, or you wait for 5 seconds and the device will return back to normal state of the buttons and timer is not stopped. The same applies also to Pause; however, if the timer is already paused, then stopping is done as usual, without LockStop feature.

Wear-Phone Synchronization

Both timers - on the phone as well as on the wearable device - can work in tandem and you can control one device from the other. The synchronization mode you can enable via Settings on either Phone or Wearable timer (Wear-Phone sync or Phone-Wear sync).

• If you open the Wear timer, go to Settings, and enable synchronization, your wearable device will become the master and phone the slave. Most of settings and all timer operations are transferred to the phone and executed on the phone timer as well.
• You can do the same also on the Phone timer. All will work in the opposite direction.
• You can even enable sync on both sides. Then you can control timer from any of both devices and the other will be synchronized.
• If you enable synchronization only in one direction (only on phone or only on the wearable device), it is recommended not to control the "slave" device by hand. If you e.g., run the timer on the master device and stop the slave device, master one will still run, slave will be stopped.
• Before you start the timer with synchronization enabled, make sure that it is stopped on the slave device, otherwise commands will be ignored on the slave device.
• If synchronization is enabled, application vibrates also on reception of command over the synchronization interface. This is switched on automatically if the Vibrate on touch option in the Settings is on. It allows you to see that something was transferred from the other device.
• Some error states can be detected on the slave device. The device will then vibrate "SOS" pattern (...---...) to inform you that something went wrong. A typical error condition can be desynchronization when the slave device cannot process the command from the master since the user switched the slave timer into some incompatible state. If you perceive the SOS vibration or any other error state, stop the timer on both devices and then run again from the master one.
• Synchronization between Wear device and Phone can take some time. I recommend you to start the application on both devices by hand before synchronization is used; also I recommend to always check if the slave timer is doing what you want. Synchronization with Wear and Phone devices connected using Bluetooth seems to me faster than synchronization over Wi-Fi and through cloud. Thus direct Bluetooth connection bewtween the smart watch and phone is recommended.

NOTE:

Running timer can discharge your phone battery faster than usual (especially if you disable sleep mode and do not enable screen dimming). If you are in doubt, try in advance how fast your battery will discharge (especially if you do not let the timer dim the screen and keep the phone on).

Setup via Sharing

It can easily happen that you get such an SMS:

Hi PaPacut, your presentation is scheduled from 2:30 PM to 3:30 PM

Then you can set up the timer to count the time till the end of the event stated in the SMS. Just do long tap on the SMS, select Share, share your SMS with the Silent Presentation Timer and the timer will automatically setup and run. The Timer extracts from the SMS the latest time and sets up according to it. The red and orange alert configurations are left as you set it up.

Similarly, if you have the meeting in your calendar, you can easily share the calendar record with the timer application and the timer will be set up to the end of your meeting by itself.

Note: you can also use the timer to warn you that your public transport ticket will soon become invalid. SMS public transport tickets usually look like the following:

Transport ticket 20 Kc. Valid from: 6.9.16 12:13 to: 6.9.16 12:48. Valid in all vehicles going back and forth in any direction in this city. Code XY56ESOD5

If you share the ticket with the timer, it will set up to the end of the validity (12:48 here). You can then add red time warning e.g., five minutes before the end and you will be warned at the right time before the ticket is invalid.
