Getting Enough Sleep?
I haven't needed an alarm to wake up in many years, but if you do, it has a Smart Sleep Cycle Alarm which wakes you up at the optimal time in your sleep cycle within your chosen wake-up time window. You can wake up to a song in your playlist or built-in sounds.
I had some bobbles in thinking I had started the sleep logging but didn't. That's user error. I usually put the phone on the bed near my pillow. The MotionX graphs had much more detail than my Fitbit sleep recording, although both captured about the same amount of deep sleep, bathroom trips, etc.
This app might even save your life if you discover you are not getting much deep sleep due to sleep apnea or another sleep disorder. It can be an indicator that you need to get checked out by a health professional.
The app also has a nice Almanac feature telling you time of sunrise, sunset, moonrise and moonset.
Record Your Total Daily Steps and Get Inactivity Alerts
The all-day steps operates in the background if you have iOS5, although it consumes more power. You can set the inactive shutdown time period to conserve battery life.
The Daily Steps screen shows your total active time, idle time, aerobic steps, percent of your daily goal, steps and calories burned. It's a nice graphical presentation that can be useful in spotting long periods of inactivity.
The drawback over using a traditional pedometer is that you, like me, might not wear your iPhone all day. Yes, it works if your phone is in a pack or purse, but I don't carry one of those all day, either. It's a darn clunky and heavy pedometer for all-day steps.
But as an inactivity alert and back-up all-day pedometer, it works great and, at 99 cents, is practically free compared to the Gruve Activity Monitor which costs 150 times more.
Log Your Walking Workouts
The app doesn't access GPS functions, so you don't get a map of your walk or GPS speed and distance. However, if you want those, you can run a GPS-enabled app at the same time.
You can calibrate your distance measurement. If you want a more accurate distance measurement, use the app on a measured course such as a track or a path that has mile markers. It is very easy to use the calibration function at the end of any workout. I came to trust this much more than the GPS distance recorded on the same walks by other apps. The GPS distance was affected by terrain, while my walking stride varied far less.
I like having the voice readout of my data, which worked well either with or without earphones.
You can share your daily steps, recorded walks, or sleep with posts to Facebook, Twitter, or via email.
