Got it for a (I think) steal around 400€ for the 45mm GPS.
Actually also got a question. How can I use the sleep function for naps? Because I slept more than that. Anyways this is cool!
i like the pillow app way better than the official sleep app, it tracks your sleep automatically. i have fallen asleep on plenty times after lunch while watching tv and somehow pillow always registered it. i use the free version btw
