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.
