Major improvements:
• intelligent snooze
• adjustable wake up phase length anything from 0 minutes (regular alarm clock mode) to 10, 15, 20, 30, 45, 60 and 90 minutes
• Sleep Cycle is now up to 5x more sensitive to your movement this is great news because better sensitivity means better wake ups
• no need to recalibrate Sleep Cycle when changing bed, pillow or mattress anymore
• full support for the iPod touch
• full iPhone 4 retina resolution support
• possibility to use music from your iPod library as alarm sound
• Sleep Cycle no longer mutes music or audiobooks that are playing in the background
• no alarm mode - use Sleep Cycle to graph your sleep, without using the alarm
Also improved:
• added swipe to navigate between graphs
• added vibration settings ("As Backup", "No vibration", "Only vibrate")
• more detailed and smoother sleep graphs
• improved performance
• screen now fades to black on iPod touches when the device is placed with the glass down
• advanced accelerometer calibration Sleep Cycle needs one or two nights to automatically calibrate to your accelerometer
• updated graphics for buttons and other UI elements
• added a regular alarm clock sound in addition to the normal wake up melodies
• if you shut down Sleep Cycle during the night and start it up again it will continue on the same graph
• warning shown on nights that are too short (less than 2.5 hours)
• warning shown on nights that Sleep Cycle has sensed no or very little movement
• small gray line below sleep graph to indicate when the alarm window started
• calculation of average total time is now done in background
• possibility to log out from Facebook (button in advanced settings)
• added a default subject line when sharing graph by email
• removed "dreaming" from graph legend we've done a lot of research around this with help from sleep scientists and determined that Sleep Cycle cannot reliably detect when you are in REM sleep
• fixed bug: fixed problems with non-gregorian calendars (like thai and japanese calendars)
• fixed bug: AM/PM being clipped in statistics view
• fixed bug: navigation arrows in statistics are now always correctly dimmed
• fixed bug: correct day of week displayed in statistics
• fixed bug: accelerometer was too sensitive on some devices producing incorrect sleep graphs this is fixed by calibrating to the accelerometer during the first two nights
• fixed bug: when shutting off the alarm the home-button now works even if the iPhone is covered by a sheet (proximity sensor problem)
• fixed bug: problem when posting to Facebook when user has changed Facebook password
• fixed bug: crash when trying to share graph by email and no email accounts where set up
