Yocto Clock User Guide & FAQ

** The current version of Yocto Clock is 1.1.1, released 30 October 2012

iOS 7 Issues: There are a couple of known issues with Yocto Clock on iOS 7:

1) Go to Yocto Clock Settings > Gestures and ensure that Proximity Sensor is OFF. If this is ON, you may find the wake-up alarm will not function as expected.

2) Adding custom wallpaper from your photo library may cause the app to crash. It will sometimes work, sometimes it will crash. To fix this, I will need to fully update the app for iOS 7, which is planned, but has been delayed do to other commitments. In the meantime, I have found that it will usually work okay if you are able to move just a few photos (3-4) into an album of their own. The problem occurs when opening bigger albums.

Orientation Stuck In Portrait Mode? (iPhone Only)

In Yocto Clock 1.1.1, the orientation will be forced to portrait mode if you enable the proximity sensor (Settings > Gestures). However, if you change your mind and then disable the proxmity sensor, it will still be in forced portrait mode. To fix this, navigate to Settings > General > Clock Panel Orientation and select "Any Orientation".

The Basics 

  • Yocto Clock always starts up with the clock display. To access the configuration screens, tap on the small button in the lower-right corner of the clock screen.
  • For the full features of wake-up alarms to function, you must leave Yocto Clock running as the active (foreground) application. So, just leave it be! The screen will lock (unless you've turned off auto-lock in the Yocto Clock settings).
  • As a safeguard (or if you don't want to leave Yocto Clock running), a backup alarm is scheduled for each wake-up alarm. Since this backup alarm is a standard system alert, your device must not have mute turned on, otherwise you will only receive a short vibration. When you tap on the "Zzz / Stop" button for the backup alarm, you'll be taken into Yocto Clock and the full-featured scheduled alarm will take over the duties of waking you up.

Wake-Up Alarms

  • The Message you specify is used not only to identify the alarm but also as a scrolling banner when the alarm fires. You can set the default in Yocto Clock's settings.
  • The time wheel is always in 24-hour time, although it will show AM/PM on all the displays if your device is set for a 12-hour clock. Why is this so? Because the vast majority of people wake up in the mornings. A frequent contributor to a missed alarm is accidentally setting it for 7:00 PM instead of 7:00 AM. With 24-hour time, it will say 19:00, which should alert you to the fact that it isn't morning :)
  • Power Nap mode allows you to set an alarm which can be instantly set at any time for X number of minutes from the current time. Perfect for power naps (which really work!).
  • If the alarm is set to repeat on specified days, it will remain active unless you turn it off. If it is a one-time alarm it will automatically be turned off after use. Just tap the power button to turn it on and reschedule for the same time the next day.
  • If you tap on the power button for a repeating wake-up alarm you will be given an option to skip the next alarm. This is handy in cases where you wake-up on your own just before the alarm fires and want to skip it, but still have the alarm set for the next day.

Sleep Timers

  • There are three types of sleep timers:
  • Soundscape -- Fall asleep to looping sounds. Includes nature / outdoors, instruments and white noise sounds.
  • iTunes -- Fall asleep to your favorite selections from your iTunes library. Check out Pod Mode -- Plays the first item for a limited time, then moves on. For more details, tap here.
  • External Audio Mode -- This allows you to use other apps to play audio (such as internet radio) and Yocto Clock will fade-out and stop the audio when the sleep timer expires. When you are ready to sleep, exit Yocto Clock, run the other app and start the audio, then return to Yocto Clock and activate the sleep timer. 

Gestures

Yocto Clock has several gestures:

  • 1-Finger Slide up/down -- Adjust clock brightness
  • 2-Finger Slide up/down -- Adjust screen (hardware) brightness. Note that the hardware brightness setting on iOS has a design quirk. If you exit the app with the brightness adjusted, it will remain at that level until the screen is locked / unlocked.
  • Shake Device -- Snooze alarm. This works from the lock screen also!
  • Single Tap Weather Text -- This will toggle between the forecast and current conditions.
  • Double Tap -- activates the flashlight (on/off). If your hardware has an LED flash, it will use this for the flashlight. Otherwise a bright white screen is displayed.
  • Long Press -- Change wallpaper
  • Proximity Sensor (iPhone only) -- This will sleep the display without locking it. This can be very handy. Set your alarm and enable your sleep timer, then turn your iPhone upside down on your nightstand. This will turn off the display, saving battery life, yet the screen will remain unlocked. So if you want to check the time or use the flashlight in the middle of the night, you are ready to go. Same when it goes off -- no need to unlock.

Settings

Yocto Clock has a complete set of options to maximize your enjoyment.

  • Default Melody -- This is not only the default choice when you create a new alarm, but is also used as the sound for the backup alarm if you specify an iTunes playlist for the alarm.
  • Device Auto-Lock -- This specifies the time that the auto-lock timer is disabled. So, if your device is set to auto-lock after 5 minutes and you set Yocto Clock's auto-lock for 5 minutes, then the device will lock 10 minutes after you last use it.
  • Force Built-In Speaker -- When this is ON, the alarm will still play through the speaker even if you have a headset plugged in or are connected to a dock. Due to technical considerations, this mode only works with the built-in melodies, so if you have an iTunes playlist selected and your headset is plugged in, you will still hear an alarm, but it will be the default melody. Not only is this a safety feature, but can be a benefit if you want to fall asleep listening with your headset, but still want to wake up with a loud alarm.
  • Auto-Stop Alarm -- This will prevent the dreaded situation where you leave the house and your alarm goes off while you are not there. Be default, the alarm will continue to go off until your dog and neighbors have gone stir-crazy. This option works with the full-featured alarms as well as the backup alarm.
  • Clock Panel Orientation (iPhone / iPod touch only) -- Provides total control over your preferred orientation (landscape or portrait) for the Clock Panel.
  • Clock Appearance -- Choose any color under the rainbow and select from several fonts for the time display.
  • Wallpaper -- In addition to a selection of built-in wallpaper, you can choose from the photo library on your device. You can select "Change Every" to set an automatic interval when the wallpaper will change. And you can always change it anytime by using the long-press gesture.
  • Weather -- By default, Yocto Clock uses your current location for the weather. You can turn Auto Location OFF to bypass Location Services and choose a custom location. The Auto Cycle setting is used to cycle between the forecast and current conditions. Tap on the weather text to manually cycle.

Miscellaneous

  • It is okay to enable Silent Mode (mute) when using wake-up alarms / sleep timers as long as Yocto Clock is left running as the active foreground app.
  • You can tap the Edit button to manually rearrange the order of wake-up alarms and sleep timers.
  • Use the power button to turn alarms / sleep timers on and off. You can have multiple wake-up alarms active at once. 
  • When you turn on the LED flashlight and your device is running on battery power, a timer is set to automatically shut off the flashlight in 90 seconds. You can always turn it on again if needed.
  • If you want a black background for your clock display, just un-check all wallpaper selections.
  • If you get a message, "Due to your device setup, external audio can't be stopped while the screen is locked.", the easiest solution is to go to Settings > General > Device Auto-Lock (within Yocto Clock) and choose a value longer than your sleep timer.
