The sleep graph Xircle Band records splits a night into awake, light, deep and REM stages laid out in the order they actually happened. The first thing worth looking at is not each individual bar, but the overall shape — whether the night was continuous or repeatedly broken into short stretches.
Deep sleep and REM are the two stages most often discussed as significant, but more is not automatically better — the right balance differs from person to person. What is more useful is watching your own trend across several nights: whether these proportions shift alongside changes in routine, like a day of exercise or a stressful one.
Short awake moments during the night are normal and happen to everyone — they are not automatically a sign of a problem. What is actually worth watching is a frequency or length of awake time that has genuinely increased compared with your own usual pattern, not the mere presence of one.
The Xircle app already summarises last night into a simple number on the home screen. For anyone who wants the full detail, the complete graph lives on the sleep history page. See how to connect an Xircle Band on the product page.
