One tap removes your account and every log, permanently.
It does one thing: log a nap or a night, and it tells you when the next sleep should start — 2:15 PM, not “soon.” I wrote the wake-window and jet-lag math during 34 days in Italy with our toddler, six time zones from home, because every nap chart I found assumed you never left the house. It held the schedule the whole trip, so I cleaned it up in case your nights look like ours did. Free, no card. If you try it, tell me what breaks.
