Weight, sleep, supplements, water and fasting.
Log a weigh-in from the Weight page or the dashboard widget. The page shows your latest reading, a 7-day average, your 30-day change and weekly rate of change, a chart, and full history you can edit or delete from. If you've set a target weight and date on the Goals page, a projection shows whether your current rate gets you there in time.
Log a night from the Sleep page: pick the date, either a duration or a bedtime and wake time (Bissbilanz works out the duration for you), a quality rating and, optionally, wake-ups and notes. The page charts your trend and lists your history.
Create a supplement on the Supplements page with its schedule (daily, every other day, weekly or specific days) and reminder time, and it shows up as a checklist on the dashboard and its own page — tap to mark it taken for the day. Taking it also logs the nutrients it carries, if you gave it any.
Track water intake from the day properties card on any day's log — it shows progress toward your daily goal, which you can change in Settings. The same card also holds manual activity calories and a free-text note for the day.
Start a fast from the Fasting page with a target duration; it runs as a live timer until you end it, and the finished session is saved to your history with your average this week, your longest fast, and whether you reached your target. If a day has no entries because you fasted rather than forgot to log, mark it a Fasting Day from its day properties so it's counted as an intentional zero-calorie day in statistics and predictions instead of being treated as missing data.
