With iNap, worry-free naps on metro bus is finally a reality
Update 4/3/2009:
Another thing that can mess up a running iNap is alert from calendar event. If a calendar alert shows up on the lock screen and you slide to unlock the screen, this act will cause iNap to quit, switching to the Calendar app. As long as you do not unlock the screen, iNap remains active. I believe this should be the case as well when you get a text message with preview on.
Purchasing iNap was the best $0.99 i have ever spent. After missing my stop at work this morning, i promptly bought iNap from App Store.
iNap is very easy to use. The first thing i did was to configure a destination. I was able to search for my destinations by their addresses or a landmark like Seattle Center.

After finding my destination, i was able to save it.

On the main iNap screen, i chose my destination.

There are about 10 sounds that i can choose from. I picked the “Fire Alarm” sound, as this was a sound that would have no problem waking me up. It is also possible to choose vibrate only.

As iPhone 2G has no GPS capability, i set the Alert Radius to 1 mile from my destination. Based on my experience with location feature of iPhone 2G, i can probably set the Alert Radius to be smaller.
The last thing i did was to set “Wake me up” to ON.
Either i was extremely tired or very trusting of iNap, almost immediately after i got on the bus, i fell asleep again. At about a mile from Seattle Center, iNap woke me up!
One caveat about using iNap is to turn off preview for text messages. If text message preview is on, it will disable iNap when you get a new text message.
