Because there is no honest single number, and pretending otherwise is the main thing wrong with the category.
The only method ever shown to measure an individual's sleep need is watching what they do when nothing forces them awake. In the key study, fifteen men of almost identical age needed anywhere from 7.3 to 9.3 hours — and their usual sleep only loosely predicted it. Body weight, sex and whether you are a morning person do not predict it either.
So Building Bed Debt learns yours instead of quoting an average at you.
It needs about two weeks of nights before it shows a range at all, and it says so until then. The more nights it has, the tighter the range gets — and it tells you how many of your last 90 nights the estimate is based on, rather than presenting a guess as a fact.
Check iOS Settings → Privacy & Security → Health → Building Bed Debt and make sure sleep is switched on. If you use a Garmin device, its own app has to be writing sleep into Apple Health first — Building Bed Debt reads Apple Health, not the watch directly.
When it spots a run of short nights it asks you one question: is something going on this week, and will it pass? Your answer decides what it does next — a week you can do something about and a week you simply have to get through are not treated the same. It does not decide that for you, and it has no streak to break.
Delete the app. Everything is on your device. You can also revoke its Health permission in iOS Settings at any time.

Yes. Everything in the app today is free: logging by hand or from Apple Health, history and ranges, the bad-week controls, notes, both exports, deleting your data and the accessibility features.
Two files. A text export gives totals only, with no per-night detail. A JSON export has one entry for each night.
Everything is stored on your device. You can revoke the app’s Health permission in iOS Settings at any time.
Delete the app. Everything is on your device, so deleting the app removes it. You can also revoke the Health permission separately.
