Fasting tools
Track an intermittent-fasting window alongside meals
Use BiteCheck’s fasting timer with meal logging, calorie and macro progress, weight trends, and glanceable daily status.
What you can do
BiteCheck combines an intermittent-fasting timer with calorie, macro, meal, and weight tracking, helping you see timing and nutrition in one daily routine.
See timing and nutrition together
A timer records when a fasting window starts and ends. Combining that timeline with a food diary makes it easier to see what you ate around the window instead of treating the timer as an isolated streak.
Choose common schedules such as 16:8 and 18:6 or set custom timing that fits your routine.
Glanceable progress
The iPhone experience can surface fasting progress through a Live Activity, and Apple Watch support keeps relevant status closer during the day.
Notifications and countdowns make it easier to remember when your chosen window starts and ends.
Choose a routine that supports your wellbeing
Fasting needs are personal. If you are pregnant, under 18, have an eating disorder or history of disordered eating, use glucose-lowering medication, or manage a medical condition, ask a qualified healthcare professional what is appropriate for you.
BiteCheck helps you record your chosen schedule alongside meals and progress.
