1. The product definitely can be used for nighttime sleep as well. Several of our initial testers actually use the mask to sleep at night and it wakes them up later in the morning via its simulated sunrise. (perfect for people who like to sleep and wake up late and don't want the son glaring on them through the blinds).

2. The final product will not be Arduino programmable, but if you'd like a developer/Arduino version in lieu of a production-run mask, drop us a line on the KS page and we can hook you up. Also, if you happen to live in Boston or the Bay Area and sign up to be an Uber early tester, you'll get both Arduino version and the final prodution versions (and all versions in between) of the Napwell.

3. This has been something that a lot of people have requested, and we're considering make a separate velcro-able module for such functionalities.
