Ana: Polyphasic Sleep Planner

Ana is a polyphasic sleep scheduler for people who sleep in more than one block a day. Draw your sleep on a dial, put it in your calendar, and get an alarm when each block ends. DRAW YOUR DAY • Drag around the dial to add a block: a core sleep, a nap, or any custom block with a name and a colour • Start from a template (Everyman, Uberman, Dymaxion, Biphasic and more) or build your own • Not on a 24-hour day? Set any day length from 12 to 48 hours YOUR CALENDAR FOLLOWS YOUR SLEEP • One tap writes your blocks to a calendar Ana creates on your phone, about three months ahead • Change your pattern from a day you choose and the calendar updates to match • Ana only ever touches its own calendar, never your other events • Remove everything Ana added whenever you like, in Settings A WAKE-UP ALARM FOR EACH BLOCK • Ana rings its own alarm when a sleep block ends, even after a restart • Switch the alarm off for any block that does not need one • No snooze on purpose: a snooze on a 20-minute nap is a hazard WILL I BE AWAKE FOR THAT? • Check a future appointment against your pattern, with your get-ready and commute time included PRIVATE BY DESIGN • No account, no sign-in. Your schedule stays on your phone • Ana sends none of your information anywhere. The one exception is Google's ad service, which never sees your schedule • Free, with a banner ad. Prefer quiet? Watch one short ad and the banner hides for 24 hours Share a pattern as a small template file with a friend, or import theirs. Ana is a planning tool, not medical advice. Talk to a health professional before changing how you sleep.
