Decent but missing key features – Polyphasic sleep Review

The app is well made and easy to use, but it really needs a custom option. It's nice to have the built in schedules, but it doesn't have the true bi-phasic option (approximately sunset to sunrise waking up for a couple hours in the middle of the night). I would either like that as an option or the ability to create a custom schedule. I disagree with the requests for 12 hour time because it's important to consider a true 24 hour day for sleep schedules. It's also true that the in app purchases are basically required for everything, but it's $1 so not really a big deal.
