I recently got the glow, and am overall satisfied with the purchase! This is a sleek, minimalist, and well working product, and I'm happy with it, but there are some features that I hope will be added in a future software update.
1- More in depth scheduling
Specifically, the ability to have different wake up times for different days. I wake up at 6 on weekdays, but definitely not on weekends. The light coming on isn't useful on those days and I'd like to see the ability to schedule wake-up times per day. In addition, while flipping the lamp to start the dimming sequence is useful, I like to use it as a regular lamp sometimes too, without the dim. Setting the dim to only work in a certain time period (say, the times you go to sleep) would be very useful.
2- Integration
Currently, the app is the only software based way to control the light, and this is a little limiting. I don't know if it would be a software update thing, but I'd like to see integration with things like IFTTT, HomeKit, and Siri. These would be useful in adding the Glow to a nighttime routine.
Overall, this is a great product! It's modern and pretty cool, and the physical controls are interesting and easy to use. But there some work to be done on the software side. I hope that updates come bringing some more features, making the Glow even better than it already is.
